Contraindications



  • Known hypersensitivity to fexofenadine or any ingredient in the formulation.1 77 88



Warnings/Precautions


Sensitivity Reactions


Rash, urticaria, pruritus, and hypersensitivity reactions (e.g., angioedema, chest tightness, dyspnea, flushing, anaphylaxis) reported rarely.1 77 88


General Precautions


Fixed-combination Preparations

When used in fixed combination with pseudoephedrine, consider the cautions, precautions, and contraindications associated with pseudoephedrine.77 88


Specific Populations


Pregnancy

Category C.1 77 88


Lactation

Not known if fexofenadine is distributed into milk; however, pseudoephedrine (a component of the fixed-combination preparations) distributes into milk.77 88 Use with caution in nursing women.1 77 88 Discontinue nursing or fixed-combination preparation.77 88


Pediatric Use

Conventional tablets or capsules: Safety and efficacy not established in children <6 years of age.1 2


Extended-release fexofenadine hydrochloride/pseudoephedrine hydrochloride preparations: Safety and efficacy not established in children <12 years of age; use not recommended in this age group.77 88 Doses of fexofenadine hydrochloride and pseudoephedrine hydrochloride in these preparations exceed those recommended for children <12 years of age.77 88


Risk of overdosage and toxicity (including death) in children <2 years of age receiving OTC preparations containing antihistamines, cough suppressants, expectorants, and nasal decongestants alone or in combination for relief of symptoms of upper respiratory tract infection.89 90 Limited evidence of efficacy for these preparations in this age group; appropriate dosages not established.89 Therefore, FDA recommended not to use such preparations in children <2 years of age; safety and efficacy in older children currently under evaluation. Because children 2–3 years of age also are at increased risk of overdosage and toxicity, some manufacturers of oral nonprescription cough and cold preparations recently agreed to voluntarily revise the product labeling to state that such preparations should not be used in children <4 years of age. During the transition period, some preparations on pharmacy shelves will have the new recommendation (“do not use in children <4 years of age”), while others will have the previous recommendation (“do not use in children <2 years of age”). FDA recommends that parents and caregivers adhere to dosage instructions and warnings on the product labeling that accompanies the preparation and consult a clinician about any concerns. Clinicians should ask caregivers about use of OTC cough/cold preparations to avoid overdosage.


Geriatric Use

Insufficient experience in patients ≥65 years of age in clinical trials, but other clinical experience has not identified overall differences in response relative to younger patients.1 77 88


Risk of severe adverse reactions may be increased in patients with impaired renal function since fexofenadine is substantially excreted by the kidney.1 Select dosage carefully due to greater frequency of decreased renal function;1 77 renal function monitoring may be useful.1 77 88


Renal Impairment

Dosage reduction necessary.1 77 (See Renal Impairment under Dosage and Administration.)


Avoid use of fixed-combination preparation containing 180 mg of fexofenadine hydrochloride and 240 mg of pseudoephedrine hydrochloride (Allegra-D 24 Hour) in patients with renal impairment; possible risk of pseudoephedrine accumulation.88


Common Adverse Effects


Children 6–11 years of age receiving conventional tablets: Headache, upper respiratory tract infection, coughing, accidental injury, fever, pain, otitis media.1


Adults and children ≥12 years of age receiving conventional capsules or tablets: Viral infection (e.g., cold, flu), nausea, dysmenorrhea, sinusitis, dizziness, drowsiness, dyspepsia, fatigue, headache, upper respiratory tract infection, back pain.1


Fixed-combination fexofenadine hydrochloride (60 mg)/pseudoephedrine hydrochloride (120 mg): Headache, insomnia, nausea, dry mouth, dyspepsia, throat irritation, dizziness, agitation, back pain, palpitation, nervousness, anxiety, upper respiratory tract infection, abdominal pain.77


Interactions for Fexofenadine Hydrochloride


Minimally metabolized by CYP microsomal enzymes.1


When using fixed-combination preparations containing pseudoephedrine hydrochloride, consider the drug interactions associated with pseudoephedrine.77 88

In patients with mild to severe renal impairment (Clcr of 11–80 mL/minute) and in those on hemodialysis (Clcr ≤ 10 mL/minute), peak plasma fexofenadine concentrations were increased by 87–111 and 82%, respectively, compared with those in healthy adults.1 77 88


In geriatric patients ≥65 years of age, peak plasma fexofenadine concentrations were 99% greater than in younger adults.1 2 36 77 79 88


Distribution


Extent


Distribution into human body tissues and fluid not fully elucidated;2 distributes into the small and large intestines, stomach, pancreas, liver, and kidney in animals.2 Distributed more extensively into plasma than blood or saliva.2 Does not appear to cross the blood-brain barrier.1 2 77 79 81 88


Not known whether fexofenadine crosses the placenta or distributes into milk.2


Plasma Protein Binding


60–70% (mainly albumin and α1-acid glycoprotein).1 2 77 88


Elimination


Metabolism


About 0.5–1.5% of a dose is metabolized in the liver by CYP enzymes, while about 3.5% is metabolized by a second metabolic pathway.70


Elimination Route


Excreted in feces (80%) and urine (11–12%).1 2 77 79 81 88


Half-life


14.4–14.6 hours.1 2 77 88


Special Populations


In patients with mild to severe renal impairment (Clcr of 11–80 mL/minute) and in those on hemodialysis (Clcr ≤10 mL/minute), half-life was 59–72 and 31% longer, respectively, compared with that in healthy adults.1 77 88


Stability


Storage


Oral


Capsules and Tablets

  • Specific, selective, histamine H1-receptor antagonist.1 2 3 18 19 20 22 80




  • Lacks cardiotoxic potential of terfenadine15 16 17 36 66 67 80 since it does not block the potassium channel involved in repolarization of cardiac cells (i.e., blockade of the delayed rectifier potassium current IK).1 8 16 36 66 67 80




  • No appreciable anticholinergic,1 2 77 80 88 antidopaminergic,2 or α- or β-adrenergic blocking1 77 88 effects at usual antihistaminic doses in pharmacologic studies.




  • In clinical studies, incidence of CNS effects (e.g., sedation, EEG disturbances, impaired psychomotor performance) associated with fexofenadine is similar to that with placebo and less than that with first generation antihistamines (e.g., chlorpheniramine, clemastine, diphenhydramine, triprolidine).1 70



Advice to Patients



  • Importance of taking only as prescribed; do not exceed prescribed dosage.77 88




  • Importance of consulting a clinician if nervousness, dizziness, or sleeplessness occurs with fixed-combination preparations containing pseudoephedrine hydrochloride.77 88




  • Importance of swallowing fixed-combination tablets whole; do not break, crush, or chew.77 88 Inform patients that inert ingredients of Allegra-D 12 Hour tablets occasionally may be eliminated in feces in a form resembling the original tablet.77




  • Advise patients to avoid concomitant use of fixed-combination preparations with other OTC antihistamines and/or decongestants.77 88




  • Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs and dietary or herbal supplements, as well as any concomitant illnesses.1 77 88




  • Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.1




  • Importance of informing patients of other important precautionary information.1 77 88 (See Cautions.)
