HepaGam B



hepatitis b immune globulin (human)

Dosage Form: injection, solution
FULL PRESCRIBING INFORMATION

Indications and Usage for HepaGam B



Prevention of Hepatitis B recurrence following Liver Transplantation


HepaGam B®, Hepatitis B Immune Globulin Intravenous (Human), is indicated for the prevention of hepatitis B recurrence following liver transplantation, in HbsAg-positive liver transplant patients.


HepaGam B should be administered intravenously for this indication.



Postexposure Prophylaxis


HepaGam B is indicated for the treatment of acute exposure to blood containing HbsAg, perinatal exposure of infants born to HbsAg-positive mothers, sexual exposure to HbsAgpositive


persons and household exposure to persons with acute HBV infection in the following settings:


Following either parenteral exposure (needlestick, bite, sharps), direct mucous membrane contact (accidental splash), or oral ingestion (pipetting accident), involving HbsAg-positive materials such as blood, plasma or serum1,2.


Perinatal Exposure of Infants Born to HbsAg-positive Mothers


Infants born to mothers positive for HbsAg with or without HbeAg1.


Sexual Exposure to HbsAg-positive Persons


Sexual partners of HbsAg-positive persons1,2.


Household Exposure to Persons with Acute HBV Infection


Infants less than 12 months old whose mother or primary caregiver is positive for HbsAg. Other household contacts with an identifiable blood exposure to the index patient.


HepaGam B is indicated for intramuscular use only for these post-exposure prophylaxis indications.



HepaGam B Dosage and Administration


Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration; if these are seen, vials should not be used. During preparation, do not shake vials; avoid foaming.


Any vial of HepaGam B that has been entered should be used promptly. Do not reuse or save for future use. This product contains no preservative; therefore, partially used vials should be discarded immediately.



Prevention of Hepatitis B recurrence following liver transplantation


For the prevention of hepatitis B recurrence following liver transplantation in HBsAg positive liver transplant patients, HepaGam B is administered intravenously according to a set dosing regimen designed to attain serum levels of antibodies to hepatitis B surface antigen (anti-HBs) greater than 500 IU/L3.


Based upon the HepaGam B clinical trial, patients should receive 20,000 IU/dose [see Clinical Trials in Liver Transplant Patients (14.1)]. The volume of each 20,000 IU dose should be calculated from the measured potency of the particular lot of HepaGam B as stamped on the vial label.


The first dose should be administered concurrently with the grafting of the transplanted liver (the anhepatic phase) with subsequent dosing as recommended in Table 1.












Table 1 - HepaGam B Dosing Regimen

Anhepatic Phase



Week 1 Post-Operative



Weeks 2-12


Post-Operative



Month 4 onwards


First doseDaily from Day 1-7Every two weeks from Day 14Monthly

* Each dose should contain 20,000 IU calculated from the measured potency as stamped on the vial label [see Dosage Forms and Strengths (3)].


HepaGam B dose adjustments may be required in patients who fail to reach anti-HBs levels of 500 IU/L within the first week post-liver transplantation4. Patients who have surgical bleeding or abdominal fluid drainage (> 500 mL) or patients who undergo plasmapheresis are particularly susceptible to extensive loss of circulated anti-HBs. In these cases, the dosing regimen should be increased to a half-dose (10,000 IU calculated from the measured potency as stamped on the vial label) intravenously every 6 hours until the target anti-HBs is reached.


Hepatitis B Immune Globulin (HBIG) products are most effective in patients with no or low levels of HBV replication at the time of transplantation5.


Regular monitoring of serum HBsAg and levels of anti-HBs antibody should be performed pre-infusion to track treatment response and allow for treatment adjustment.


HepaGam B should be prepared for intravenous administration under aseptic conditions. HepaGam B should be administered through a separate intravenous line using an intravenous administration set via infusion pump.


The rate of administration should be set at 2 mL per minute.


The rate of infusion should be decreased to 1 mL per minute or slower if the patient develops discomfort, infusion-related adverse events or there is concern about the speed of infusion.



Postexposure Prophlyaxis


For postexposure prophylaxis indications, HepaGam B must be administered intramuscularly only as directed below.


It is important to use a separate vial, sterile syringe, and needle for each individual patient, to prevent transmission of infectious agents from one person to another.


HepaGam B may be administered at the same time (but at a different site), or up to one month preceding hepatitis B vaccination without impairing the active immune response to Hepatitis B Vaccine1,2.


Acute Exposure to Blood Containing HBsAg


Table 2 summarizes prophylaxis for percutaneous (needlestick, bite, sharps), ocular, or mucous membrane exposure to blood according to the source of exposure and vaccination status of the exposed person. For greatest effectiveness, passive prophylaxis with HepaGam B should be given as soon as possible after exposure, as its value after seven days following exposure is unclear1,2. An injection of 0.06 mL/kg of body weight should be administered intramuscularly as soon as possible after exposure, and within 24 hours if possible. Consult the Hepatitis B Vaccine package insert for dosage information regarding the vaccine.


For persons who refuse Hepatitis B Vaccine or are known non-responders to vaccine, a second dose of HepaGam B should be given one month after the first dose2.

Prophylaxis of Infants Born to Mothers who are Positive for HBsAg with or without HBeAg


Table 3 contains the recommended schedule of Hepatitis B prophylaxis for infants born to mothers that are either known to be positive for HBsAg or have not been screened. Infants born to mothers known to be HBsAg-positive should receive 0.5 mL HepaGam B after physiologic stabilization of the infant and preferably within 12 hours of birth. The Hepatitis B Vaccine series should be initiated simultaneously, if not contraindicated, with the first dose of the vaccine given concurrently with the HepaGam B, but at a different site. Subsequent doses of the vaccine should be administered in accordance with the recommendations of the manufacturer. Women admitted for delivery, who were not screened for HBsAg during the prenatal period, should be tested. While test results are pending, the newborn infant should receive Hepatitis B Vaccine within 12 hours of birth (see manufacturers’ recommendations for dose). If the mother is later found to be HBsAg-positive, the infant should receive 0.5 mL HepaGam B as soon as possible and within seven days of birth; however, the efficacy of HepaGam B administered after 48 hours of age is not known6. Testing for HBsAg and anti-HBs is recommended at 12-15 months of age. If HBsAg is not detectable and anti-HBs is present, the child has been protected1.

Sexual Exposure to HBsAg-positive Persons


All susceptible persons whose sexual partners have acute hepatitis B infection should receive a single dose of HepaGam B (0.06 mL/kg) and should begin the Hepatitis B Vaccine series, if not contraindicated, within 14 days of the last sexual contact or if sexual contact with the infected person will continue. Administering the vaccine with HepaGam B may improve the efficacy of post exposure treatment. The vaccine has the added advantage of conferring long-lasting protection1,2.


Household Exposure to Persons with Acute HBV Infection


Prophylaxis of an infant less than 12 months of age with 0.5 mL HepaGam B and Hepatitis B Vaccine is indicated if the mother or primary caregiver has acute HBV infection. Prophylaxis of other household contacts of persons with acute HBV infection is not indicated unless they had an identifiable blood exposure to the index patient, such as by sharing toothbrushes or razors. Such exposures should be treated like sexual exposures. If the index patient becomes an HBV carrier, all household contacts should receive Hepatitis B Vaccine1,2.



Dosage Forms and Strengths


HepaGam B, Hepatitis B Immune Globulin Intravenous (Human), is a sterile solution of purified gamma globulin (5% or 50 mg/mL) containing anti-HBs. Each vial contains greater than 312 IU/mL of anti-HBs and is supplied in a carton containing a 1.0 mL single use vial or a carton containing a 5.0 mL single use vial. The measured potency of each lot is stamped on the vial label.


To ensure that the label claim of >312 IU/mL is maintained over the product shelf life, a higher potency of 550 IU/mL is targeted at the time of manufacture. As with other specific immune globulin products, this higher target potency is a manufacturing requirement to account for variability in the potency assay and changes in potency over time. The potency assay has a relative standard deviation (RSD) of approximately 10%. Based on statistical assessment of manufactured lots with a target potency of 550 IU/mL, the actual potency test result may vary from approximately 400 to 700 IU/mL (3x RSD). The measured potency is provided on the container label. Due to the inherent variability of the potency assay, dosing for the prevention of hepatitis B recurrence following liver transplantation should be calculated from the measured potency of the particular lot of HepaGam B as stamped on the vial label [see Dosage and Administration (2.1)].



Contraindications


Individuals known to have anaphylactic or severe systematic reactions associated with the parenteral administration of human globulin preparations should not receive HepaGam B, Hepatitis B Immune Globulin Intravenous (Human), or any other human immune globulin. HepaGam B contains less than 40 micrograms/mL of IgA. Individuals who are deficient in IgA may have the potential to develop IgA antibodies and have an anaphylactoid reaction. The physician must weigh the potential benefit of treatment with HepaGam B against the potential for hypersensitivity reactions.


For postexposure prophylaxis indications, HepaGam B must be administered intramuscularly only. In patients who have severe thrombocytopenia or any coagulation disorder that would contraindicate intramuscular injections, HepaGam B should be given only if the expected benefits outweigh the potential risks.



Warnings and Precautions



General


HepaGam B is made from human plasma. Products made from human plasma may contain infectious agents, such as viruses and theoretically, the Creutzfeldt-Jakob disease agent. The risk that such products can transmit an infectious agent has been reduced by screening plasma donors for prior exposure to certain viruses, by testing for the presence of certain current virus infections, and by inactivating and/or removing certain viruses. The HepaGam B manufacturing process includes a solvent/detergent treatment step (using tri-n-butyl phosphate and Triton X-100) that is effective in inactivating known enveloped viruses such as HBV, HCV, and HIV. HepaGam B is filtered using a Planova 20N Virus Filter that is effective in reducing the levels of some enveloped and non-enveloped viruses. These two processes are designed to increase product safety. Despite these measures, such products can still potentially transmit disease. There is also the possibility that unknown infectious agents may be present in such products. ALL infections thought by a physician to have been transmitted by this product should be reported by the physician or other healthcare provider to Cangene Corporation at 1-800-768-2304. The physician should discuss the risks and benefits of this product with the patient.



Anaphylactic Precautions


Although allergic reactions have not been reported following HepaGam B administration [see Adverse Reactions (6.2)], the product should be administered only in a setting where appropriate equipment and personnel trained in the management of acute anaphylaxis are available. If hypotension or anaphylaxis occurs, the administration of HepaGam B should be discontinued immediately and supportive care given as needed.



Interference with Blood Glucose Testing


The maltose contained in HepaGam B can interfere with some types of blood glucose monitoring systems, i.e., those based on the glucose dehydrogenase pyrroloquinequinone (GDH-PQQ) method. This can result in falsely elevated glucose readings and, consequently, in the inappropriate administration of insulin, resulting in life-threatening hypoglycemia. Cases of true hypoglycemia may go untreated if the hypoglycemic state is masked by falsely elevated results.



Monitoring: Serum anti-HBs Antibody Levels


Liver transplant patients should be monitored regularly for serum anti-HBs antibody levels using a quantitative assay [see Dosage and Administration (2.1)].



Infusion Reactions


Certain adverse drug reactions may be related to the rate of infusion. The recommended infusion rate given under Dosage and Administration (2.1) must be closely followed. Patients must be closely monitored and carefully observed for any symptoms throughout the infusion period and immediately following an infusion.



Coagulation Disorders


For postexposure prophylaxis indications, HepaGam B must be administered intramuscularly only. In patients who have severe thrombocytopenia or any coagulation disorder that would contraindicate intramuscular injections, HepaGam B should be given only if the expected benefits outweigh the potential risks.



Adverse Reactions



Overall Adverse Reaction Profile


The most common expected adverse drug reactions for intravenous immune globulins like HepaGam B are chills, fever, headaches, vomiting, allergic reactions, nausea, arthralgia and moderate low back pain7,8. In a clinical trial in liver transplant patients, 2 adverse drug reactions of tremor and hypotension were reported in 2 of 14 patients who received intravenous infusions of HepaGam B8. In studies with healthy volunteers, only 1 adverse drug reaction of nausea was reported in the 70 adult subjects who received an intramuscular administration of HepaGam B8.


Although no anaphylactic reactions have been reported following HepaGam B administration, anaphylactic reactions have been reported following the administration of other immune globulin products on rare occasions [see Warnings and Precautions (5.2)].



Adverse Reactions in Clinical Trials


Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.


Hepatitis B-Related Liver Transplantation


In an ongoing clinical trial, only 2 adverse drug reactions occurred following the 313 (<1%) HepaGam B infusions in 14 liver transplant patients. A listing of all adverse events (including those assessed as unrelated to study drug) occurring in >10% of patients are summarized in Table 4 below. These adverse events were reported in an interim analysis from a one-year Phase 3 clinical trial examining HepaGam B for the prevention of hepatitis B recurrence following liver transplantation. This study utilized the recommended dosing regimen outlined in Table 1 [see Dosage and Administration (2.1)]. The 2 attributed adverse drug reactions of tremor and hypotension were reported in 2 patients. All reactions were associated with a single HepaGam B infusion during the first week post-transplant. All reactions resolved on the same day and did not recur with subsequent HepaGam B infusions.

Healthy Volunteer Studies


Seventy healthy male and female volunteers received a single dose of HepaGam B intramuscularly in clinical trials8. Seventeen (17) subjects reported 30 adverse events following administration of HepaGam B. The most frequently reported adverse events included 4 subjects (6%) who experienced headache, 7 subjects (10%) who had cold symptoms or flu and 2 subjects (3%) who experienced lightheadedness/fainted. The majority of events were reported as mild and were not related to study drug. One adverse event, an episode of nausea, was considered to be drug related. There were no serious adverse events reported. A similar number of subjects in the comparator groups reported adverse events.



Postmarketing Experience


As of April 2007, there have been no postmarketing adverse events reported for HepaGam B administered IM



Drug Interactions



Live Attenuated Virus Vaccines


Immune globulin administration may impair the efficacy of live attenuated virus vaccines such as measles, rubella, mumps and varicella1,2,7. Vaccination with live virus vaccines should be deferred until approximately three months after administration of HepaGam B, Hepatitis B Immune Globulin Intravenous (Human). Persons who received HepaGam B less than 14 days after live virus vaccination should be revaccinated 3 months after the administration of the immune globulin, unless serologic test results indicate that antibodies were produced1,2.


There are no available data on drug interactions of HepaGam B with other medications.



Drug-Laboratory Interactions: Serological Testing


Antibodies present in HepaGam B may interfere with some serological tests. After administration of immune globulins like HepaGam B, a transitory increase of passively transferred antibodies in the patient’s blood may result in misleading positive results in serological testing (e.g. Coombs' test).



Drug-Laboratory Interactions: Blood Glucose Testing


HepaGam B contains maltose which can interfere with certain types of blood glucose monitoring systems. [See Warnings and Precautions (5.3).] Only testing systems that are glucose-specific should be used in patients receiving HepaGam B. This interference can result in falsely elevated glucose readings that can lead to untreated hypoglycemia or to inappropriate insulin administration, resulting in life-threatening hypoglycemia.


The product information of the blood glucose testing system, including that of the test strips, should be carefully reviewed to determine if the system is appropriate for use with maltose-containing parenteral products. If any uncertainty exists, contact the manufacturer of the testing system to determine if the system is appropriate for use with maltose-containing parenteral products.



USE IN SPECIFIC POPULATIONS



Pregnancy Category C


Animal reproduction studies have not been conducted with HepaGam B. It is also not known whether HepaGam B can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. HepaGam B should be given to a pregnant woman only if clearly indicated.



Nursing Mothers


It is not known whether HepaGam B is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when HepaGam B is administered to a nursing mother.



Overdosage


Consequences of an overdose are not known. Although no data are available, clinical experience reported with other intravenously administered human immune globulin preparations suggests that doses above 1 g immune globulin/kg body weight are tolerated. For intramuscular administration of HepaGam B, the only manifestations of overdose would be pain and tenderness at the injection site.



HepaGam B Description


HepaGam B, Hepatitis B Immune Globulin Intravenous (Human), is a solvent/detergent-treated sterile solution of purified gamma globulin containing anti-HBs. It is prepared from plasma donated by healthy, screened donors with high titers of anti-HBs that is purified by an anion-exchange column chromatography manufacturing method9,10. HepaGam B is formulated as a 5% (50 mg/mL) protein solution with 10% maltose and 0.03% polysorbate 80 at pH 5.6. It is available in 1 mL and 5 mL single dose vials. The product appears as a clear to opalescent liquid. It contains no preservatives and is intended for single use. HepaGam B may be administered intravenously or intramuscularly dependent upon indication [see Indications and Usage (1.)]. The source plasma used in the manufacture of this product was tested by FDA licensed Nucleic Acid testing (NAT) for HIV-1 and HCV and found to be negative. An investigational NAT for HBV was performed on all Source Plasma used, and found to be negative; however, the significance of a negative result has not been established. Plasma also has been tested by inprocess NAT for hepatitis A virus (HAV) and parvovirus B19 (B19) via minipool testing and the limit for B19 in the manufacturing pool is set not to exceed 104 IU of B19 DNA per mL.


The manufacturing process contains two steps implemented specifically for virus clearance. The solvent and detergent step (using tri-n-butyl phosphate and Triton X-100) is effective in the inactivation of enveloped viruses, such as hepatitis B, hepatitis C and HIV11. Virus filtration, using a Planova 20N virus filter, is effective for the removal of viruses based on their size, including some non-enveloped viruses12. These two viral clearance steps are designed to increase product safety by reducing the risk of transmission of enveloped and non-enveloped viruses. In addition to these two specific steps, the process step of anion-exchange chromatography was identified as contributing to the overall viral clearance capacity for small non-enveloped viruses.


The inactivation and reduction of known enveloped and non–enveloped model viruses were validated in laboratory studies as summarized in Table 5. The viruses employed for spiking studies were selected to represent those viruses that are potential contaminants in the product, and to represent a wide range of physiochemical properties in order to challenge the manufacturing process’s ability for viral clearance in general.

HepaGam B - Clinical Pharmacology



Mechanism of Action


HBIGIV products provide passive immunization for individuals exposed to the hepatitis B virus, by binding to the surface antigen and reducing the rate of hepatitis B infection13-16.


Hepatitis B virus reinfection following liver transplantation is the consequence of exposure of the new liver graft to hepatitis B virus. Reinfection may occur immediately at the time of liver reperfusion due to circulating virus or later from virus retained in extrahepatic sites.


The mechanism whereby hepatitis B Immune globulin (HBIG) protects the transplanted liver against HBV reinfection is not well understood. HBIG may protect naive hepatocytes against infection through blockage of a putative HBV receptor17. Alternatively, HBIG may neutralize circulating virions through immune precipitation and immune complex formation or may trigger an antibody-dependent cell-mediated cytotoxicity response resulting in target cell lysis17, 18. In addition, HBIG has been reported to bind to hepatocytes and interact with HBsAg within cells19. Regardless of the mechanism, there is evidence of a dose-dependent response to HBIG treatment5,8.



Postexposure Prophylaxis


Clinical studies conducted prior to 1983 with hepatitis B immune globulins similar to HepaGam B demonstrated the advantage of simultaneous administration of hepatitis B vaccine and Hepatitis B Immune Globulin (Human), by the i.m. route. The Centers for Disease Control and Prevention Advisory Committee on Immunization Practices (ACIP) advises that the combination prophylaxis be provided following certain instances of hepatitis B exposure.1,2 Recommendations on post-exposure prophylaxis are based on available efficacy data, primarily from studies in neonates1,2. Cases of hepatitis B are rarely seen following exposure to HBV in persons with pre-existing anti-HBs antibodies.


Infants born to HBsAg-positive mothers are at risk of being infected with HBV and becoming chronic carriers1.  The risk is especially great if the mother is also HBeAg-positive1. For an infant with perinatal exposure to an HBsAg-positive and HBeAg-positive mother, a regimen combining one dose of Hepatitis B Immune Globulin (Human) at birth with the hepatitis B vaccine series started soon after birth has been shown to be 85-98% effective in preventing development of the HBV carrier state1,2. Regimens involving either multiple doses of Hepatitis B Immune Globulin (Human) alone or the vaccine series alone have a 70-75% efficacy, while a single dose of Hepatitis B Immune Globulin (Human) alone has 50% efficacy1,2.


Since infants have close  contact with primary caregivers and have a higher risk of becoming HBV carriers after acute HBV infection, prophylaxis of an infant less than 12 months of age with Hepatitis B Immune Globulin (Human) and Hepatitis B Vaccine is indicated if the mother or primary caregiver has acute HBV infection1.


Sexual partners of HBsAg-positive persons are at increased risk of acquiring HBV infection. A single dose of Hepatitis B immune Globulin (Human) is 75% effective if administered within two weeks of the last sexual exposure to a person with acute hepatitis B1,2.


HBV infection is a well-recognized risk to health-care personnel (HCP). The risk of HBV infection is primarily related to the degree of contact with blood in the work place and also to the hepatitis B e antigen (HBeAg) status of the source person. In studies of HCP who sustained injuries from needles contaminated with blood containing HBV, the risk of developing clinical hepatitis if the blood was hepatitis B surface antigen (HBsAg) and HBeAg-positive was 22%-31%; the risk of developing serologic evidence of HBV infection was 37%-62%. In comparison, the risk of developing clinical hepatitis from needles contaminated with HBsAg-positive, HBeAg-negative blood is 1%-6%, and the risk of developing serological evidence of HBV infection is 23%-37%20. The current recommendations of the Advisory Committee on Immunization Practices1,2, recommends postexposure prophylaxis with hepatitis B immune globulin and/or hepatitis B vaccine series for any susceptible, unvaccinated person who sustains an occupational blood or body fluid exposure.


The pharmacokinetic profile of HepaGam B has been evaluated in two clinical trials [see Clinical Studies (14.2)]. The comparative bioavailability of HepaGam B and another commercially available hepatitis B immunoglobulin product indicates that HepaGam B has similar efficacy.



Nonclinical Toxicology


Nonclinical pharmacology studies have not been performed with Hepatitis B Immune Globulin Intravenous (Human) as there is broad experience in humans with intravenous and intramuscular administration of immune globulin products. Since the product is of human origin, immunogenicity is expected when administered to animals.


Toxicology studies have not been performed with Hepatitis B Immune Globulin Intravenous (Human) because the product has been formulated with ingredients that are know to be non-toxic at the levels at which they are present in the final product.



Clinical Studies



Clinical Trials in Liver Transplant Patients


A clinical trial examining the effectiveness of HepaGam B in the prevention of hepatitis B recurrence following liver transplantation is currently ongoing. The study is a multi-center, open-labeled, superiority study involving HBsAg-positive/HBeAg-negative liver transplant patients. The study included two arms, an active treatment group of patients enrolled to receive the described dosing regimen of HepaGam B starting during transplant and continuing over the course of a year, and a retrospective untreated control group of historical patients with data gathered by chart review.


An interim report of this study evaluated the data from 30 liver transplant patients, 16 HepaGam B patients who have completed the study and 14 retrospective untreated control patients. The patients in both groups were HBsAg-positive/HBeAg-negative liver transplant patients who met similar entry criteria, had similar medical history and had similar status at transplant based on MELD and/or ChildPugh-Turcotte scores.


In the active treatment group, HepaGam B doses of 35 mL started during transplant according to the regimen identified in Table 1 [see Dosing and Administration (2.1)]. As a result of the targeted potency of 550 IU/mL at the time of manufacture [see Dosage Forms and Strengths (3.)], the 35 mL doses of HepaGam B used in this study actually contained between 17,000 and 23,000 IU anti-HBs. These 35 mL doses consistently yielded anti-HBs trough levels > 500 IU/L (99% of all anti-HBs levels were > 500 IU/L; see Figure 1).


Figure 1: Frequency Histogram of Trough anti-HBs Levels more than 30 days after Transplant



Values below the target trough were only observed in the 2 patients with HBV recurrence who had anti-HBs levels <150 IU/L at the time of seroconversion.


For the efficacy endpoint of the proportion of patients with HBV recurrence (HBsAg positive and/or HBeAg positive after 4 weeks post-OLT), a significant treatment effect was observed. As summarized in Table 6, HBV recurrence was seen in 2/15 or 13% of HepaGam B patients compared to 12/14 or 86% of retrospective untreated control patients (see Table 6). One of the 16 HepaGam B patients died 2 weeks post-transplant was excluded from all efficacy analyses, but was included for safety analyses. The death was not HBV or study drug related.

Generic Name: phentermine (FEN ter meen)

Brand Names: Adipex-P, Oby-Cap, T-Diet, Zantryl


What is Zantryl (phentermine)?

Phentermine is a stimulant that is similar to an amphetamine. Phentermine is an appetite suppressant that affects the central nervous system.


Phentermine is used together with diet and exercise to treat obesity (overweight) in people with risk factors such as high blood pressure, high cholesterol, or diabetes.


Phentermine may also be used for purposes not listed in this medication guide.


What is the most important information I should know about Zantryl (phentermine)?


Do not use phentermine if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) in the last 14 days. A dangerous drug interaction could occur, leading to serious side effects. Taking phentermine together with other diet medications such as fenfluramine (Phen-Fen) or dexfenfluramine (Redux) can cause a rare fatal lung disorder called pulmonary hypertension. Do not take phentermine with any other diet medications without your doctor's advice. Phentermine may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert. Drinking alcohol can increase certain side effects of phentermine.

Phentermine is only part of a complete program of treatment that may also include diet, exercise, and weight control. Follow your diet, medication, and exercise routines very closely.


Phentermine may be habit-forming and should be used only by the person it was prescribed for. Never share phentermine with another person, especially someone with a history of drug abuse or addiction. Keep track of the amount of medicine used from each new bottle. Phentermine is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription. Do not stop using phentermine suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to avoid withdrawal symptoms when you stop using phentermine.

What should I discuss with my healthcare provider before taking Zantryl (phentermine)?

A dangerous drug interaction could occur, leading to serious side effects.

Taking phentermine together with other diet medications such as fenfluramine (Phen-Fen) or dexfenfluramine (Redux) can cause a rare fatal lung disorder called pulmonary hypertension. Do not take phentermine with any other diet medications without your doctor's advice.

Uses For halcinonide


Halcinonide topical is used to help relieve redness, itching, swelling, or other discomfort caused by skin conditions. halcinonide is a corticosteroid (cortisone-like medicine or steroid).


halcinonide is available only with your doctor's prescription.


Before Using halcinonide


In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For halcinonide, the following should be considered:


Allergies


Tell your doctor if you have ever had any unusual or allergic reaction to halcinonide or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.


Pediatric


Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of halcinonide topical in the pediatric population. However, because of halcinonide's toxicity, it should be used with caution. Children may absorb large amounts through the skin, which can cause serious side effects. If your child is using halcinonide, follow your doctor's instructions very carefully.


Geriatric


Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of halcinonide topical in the elderly.


Interactions with Medicines


Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.


Interactions with Food/Tobacco/Alcohol


Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.


Other Medical Problems


The presence of other medical problems may affect the use of halcinonide. Make sure you tell your doctor if you have any other medical problems, especially:


  • Cushing's syndrome (adrenal gland disorder) or

  • Diabetes or

  • Hyperglycemia (high blood sugar) or

  • Intracranial hypertension (increased pressure in the head)—Use with caution. May make these conditions worse.

  • Infection of the skin at or near the place of application or

  • Large sores, broken skin, or severe skin injury at the place of application—The chance of side effects may be increased.

Proper Use of halcinonide


It is very important that you use halcinonide only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered. To do so may cause unwanted side effects or skin irritation.


halcinonide is for use on the skin only. Do not get it in your eyes, nose, mouth, or vagina. Do not use it on skin areas that have cuts, scrapes, or burns. If it does get on these areas, rinse it off right away with water.


halcinonide should only be used for skin conditions that your doctor is treating. Check with your doctor before using it for other conditions, especially if you think that a skin infection may be present. halcinonide should not be used to treat certain kinds of skin infections or conditions, such as severe burns.


To use:


  • Wash your hands with soap and water before and after using halcinonide.

  • Apply a thin layer of halcinonide to the affected area of the skin. Rub it in gently.

  • Do not bandage or otherwise wrap the skin being treated unless directed to do so by your doctor.

  • If the medicine is applied to the diaper area of an infant, do not use tight-fitting diapers or plastic pants unless directed to do so by your doctor.

  • If your doctor ordered an occlusive dressing or airtight covering to be applied over the medicine, make sure you know how to apply it. Occlusive dressings increase the amount of medicine absorbed through your skin, so use them only as directed. If you have any questions about this, check with your doctor.

Dosing


The dose of halcinonide will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of halcinonide. If your dose is different, do not change it unless your doctor tells you to do so.


The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.


  • For topical dosage forms (cream and ointment):
    • For redness, itching, and swelling of the skin:
      • Adults—Apply to the affected area of the skin two to three times per day.

      • Children—Apply to the affected area of the skin two to three times per day.



Missed Dose


If you miss a dose of halcinonide, apply it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule.


Storage


Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.


Keep out of the reach of children.


Do not keep outdated medicine or medicine no longer needed.


Ask your healthcare professional how you should dispose of any medicine you do not use.


Precautions While Using halcinonide


It is very important that your doctor check the progress of you or your child at regular visits for any unwanted effects that may be caused by halcinonide.


If your or your child's symptoms do not improve within a few days, or if they become worse, check with your doctor.


Using too much of halcinonide or using it for a long time may increase your risk of having adrenal gland problems. The risk is greater for children and patients who use large amounts for a long time. Talk to your doctor right away if you or your child have more than one of these symptoms while you are using halcinonide: blurred vision; dizziness or fainting; a fast, irregular, or pounding heartbeat; increased thirst or urination; irritability; or unusual tiredness or weakness.


Stop using halcinonide and check with your doctor right away if you or your child have a skin rash, burning, stinging, swelling, or irritation on the skin.


Do not use cosmetics or other skin care products on the treated areas.


halcinonide Side Effects


Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.


Check with your doctor immediately if any of the following side effects occur:


Incidence not known
  • Blistering, burning, crusting, dryness, or flaking of the skin

  • irritation

  • itching, scaling, severe redness, soreness, or swelling of the skin

Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:

What is Hurricaine (benzocaine topical)?

Benzocaine is a local anesthetic (numbing medication). It works by blocking nerve signals in your body.


Benzocaine topical is used to reduce pain or discomfort caused by minor skin irritations, sore throat, sunburn, teething pain, vaginal or rectal irritation, ingrown toenails, hemorrhoids, and many other sources of minor pain on a surface of the body. Benzocaine is also used to numb the skin or surfaces inside the mouth, nose, throat, vagina, or rectum to lessen the pain of inserting a medical instrument such as a tube or speculum.


There are many brands and forms of benzocaine topical available and not all brands are listed on this leaflet.


Benzocaine topical may also be used for purposes not listed in this medication guide.


What is the most important information I should know about Hurricaine (benzocaine topical)?


There are many brands and forms of benzocaine topical available and not all brands are listed on this leaflet.


Benzocaine topical used in the mouth or throat may cause a life-threatening condition in which the amount of oxygen in your blood stream becomes dangerously low. This condition is called methemoglobinemia (met-HEEM-oh glo-bin-EE-mee-a) and it may occur after only one use of benzocaine or after several uses.

Signs and symptoms of methemoglobinemia may occur within minutes or up to 2 hours after using benzocaine topical in the mouth or throat. GET EMERGENCY MEDICAL HELP IF YOU HAVE ANY OF THESE SYMPTOMS: headache, tired feeling, confusion, fast heart rate, and feeling light-headed or short of breath, with a pale, blue, or gray appearance of your skin, lips, or fingernails.


Do not use benzocaine topical if you have ever had methemoglobinemia in the past. Do not use this medicine on a child younger than 2 years old without medical advice. An overdose of numbing medications can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. This is more likely to occur when using a numbing medicine without the advice of a medical doctor (such as during a cosmetic procedure like laser hair removal). Overdose symptoms may include uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).

Use the smallest amount of this medication needed to numb the skin or relieve pain. Do not use large amounts of benzocaine topical, or cover treated skin areas with a bandage or plastic wrap without medical advice. Be aware that many cosmetic procedures are performed without a medical doctor present.


Your body may absorb more of this medication if you use too much, if you apply it over large skin areas, or if you apply heat, bandages, or plastic wrap to treated skin areas. Skin that is cut or irritated may also absorb more topical medication than healthy skin.

Before using benzocaine topical, tell your doctor if you have any type of inherited enzyme deficiency, heart disease, a breathing disorder such as asthma, bronchitis, or emphysema, or if you smoke.


If you are treating a sore throat, call your doctor if the pain is severe or lasts longer than 2 days, especially if you also develop a fever, headache, skin rash, swelling, nausea, vomiting, cough, or breathing problems.


What should I discuss with my health care provider before using Hurricaine (benzocaine topical)?


Do not use benzocaine topical if you have ever had methemoglobinemia in the past. An overdose of numbing medications can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. This is more likely to occur when using a numbing medicine without the advice of a medical doctor (such as during a cosmetic procedure like laser hair removal). Overdose symptoms may include uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).

Ask a doctor or pharmacist if it is safe for you to take this medicine if you have:



  • asthma, bronchitis, emphysema, or other breathing disorder;




  • heart disease;




  • a personal or family history of methemoglobinemia, or any genetic (inherited) enzyme deficiency; or




  • if you smoke.

How should I use Hurricaine (benzocaine topical)?


Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.


Your body may absorb more of this medication if you use too much, if you apply it over large skin areas, or if you apply heat, bandages, or plastic wrap to treated skin areas. Skin that is cut or irritated may also absorb more topical medication than healthy skin.

Use the smallest amount of medicine needed to numb the skin or relieve pain. Do not use large amounts of benzocaine topical, or cover treated skin areas with a bandage or plastic wrap without medical advice. Be aware that many cosmetic procedures are performed without a medical doctor present.


This medication comes with instructions for safe and effective application. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.


To treat minor skin conditions, apply a thin layer of benzocaine topical to the affected area up to 4 times per day. If using the spray, hold the container 6 to 12 inches away from the skin. Do not spray this medication onto your face. Spray it instead on your hands and then rub it onto the face, avoiding contact with your eyes.


To treat hemorrhoids, clean the area with soap and water before applying benzocaine topical. Apply the medication up to 6 times per day. If you are using the rectal suppository, try to empty your bowel and bladder before inserting the suppository. Remove the outer wrapper from the suppository before inserting it. Avoid handling the suppository too long or it will melt in your hands.


Do not use benzocaine topical to treat large skin areas or deep puncture wounds. Avoid using the medicine on skin that is raw or blistered, such as a severe burn or abrasion.

Call your doctor if your symptoms do not improve or if they get worse within the first 7 days of using benzocaine topical. Also call your doctor if your symptoms had cleared up but then came back.


If you are treating a sore throat, call your doctor if the pain is severe or lasts longer than 2 days, especially if you also develop a fever, headache, skin rash, swelling, nausea, vomiting, cough, or breathing problems.


Store at room temperature away from moisture and heat. Do not freeze.

What happens if I miss a dose?


Since benzocaine topical is used as needed, you may not be on a dosing schedule. If you are using the medication regularly, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.


What happens if I overdose?


Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of benzocaine topical applied to the skin can cause life-threatening side effects such as uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).

What should I avoid while taking Hurricaine (benzocaine topical)?


Avoid eating within 1 hour after using benzocaine topical on your gums or inside your mouth.


Benzocaine topical is for use only on the surface of your body, or just inside the mouth, vagina, or rectum. Avoid getting this medication in your eyes. Avoid swallowing the gel, liquid, or ointment while applying it to your gums or the inside of your mouth. The throat spray or oral lozenge may be swallowed gradually during use.

Do not apply other medications to the same affected areas you treat with benzocaine topical, unless your doctor has told you otherwise.
