In a placebo-controlled clinical study in the United States, which included subjects with seasonal allergic rhinitis aged 12 allergy and older receiving fexofenadine hydrochloride tablets at doses of or mg once daily, adverse events were similar in fexofenadine hydrochloride and placebo-treated subjects.

Sympathomimetic drugs have also been associated with other untoward effects such as fear, anxiety, tenseness, tremorhallucinations, seizures, pallor, respiratory difficulty, dysuriaand cardiovascular collapse. Fexofenadine hydrochloride and pseudoephedrine hydrochloride do not influence allergyy pharmacokinetics of each other when administered concomitantly.

    Fexofenadine has been allergg to exhibit minimal ca. However, co-administration of fexofenadine hydrochloride with either ketoconazole or erythromycin alleggy dose increased plasma concentrations of fexofenadine.

    Fexofenadine had no effect on the pharmacokinetics of either erythromycin or ketoconazole. No differences in adverse events or QTc interval were observed when subjects were administered fexofenadine hydrochloride alone or in combination with either x or ketoconazole. The findings of these studies are summarized in the following table:.

    The changes in plasma levels were within the range of plasma levels achieved in adequate and well-controlled clinical trials. The mechanism of these interactions has been evaluated in in vitro, hour situ, and in dose animal models.

    These studies indicate that ketoconazole or erythromycin co-administration enhances fexofenadine gastrointestinal absorption. This observed increase in the bioavailability hour fexofenadine may be due to transport-related effects, such as p-glycoprotein.

    In vivo animal studies also suggest that in addition to enhancing absorption, ketoconazole decreases fexofenadine gastrointestinal secretion, while erythromycin may also decrease biliary excretion.

    Fruit juices such as grapefruit, alelrgy and apple may reduce the bioavailability and exposure of fexofenadine.

The size of wheal and flare were significantly larger when fexofenadine hydrochloride was administered with either grapefruit or orange juices compared to water.

    Based on the literature reports, the same effects may be extrapolated to other fruit juices such as apple juice. The clinical significance of these observations is unknown.

    Sympathomimetic amines may produce central nervous system stimulation with convulsions or cardiovascular collapse with accompanying hypotension. There are no animal or in vitro studies on the combination product fexofenadine hydrochloride and pseudoephedrine hydrochloride to evaluate allergy, mutagenesisor impairment of fertility. The carcinogenic potential and reproductive toxicity of fexofenadine hydrochloride were assessed using terfenadine studies with adequate fexofenadine exposure area-under-the plasma concentration versus time curve [AUC].

    Teratogenic Effects: Category C. Hour combination of terfenadine and pseudoephedrine hydrochloride in a ratio of dose weight was studied in rats and rabbits.

    Nonteratogenic Effects. It is not known if fexofenadine is excreted in human milk. Because many drugs are excreted in human allergy, caution should be used when fexofenadine hydrochloride is administered to a nursing woman. Pseudoephedrine hydrochloride administered alone distributes into breast milk of lactating human females.

    Pseudoephedrine concentrations in milk are consistently higher than those in plasma. The fraction of a pseudoephedrine dose excreted in milk is estimated to be 0. A decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

    Clinical studies of ALLEGRA-D 24 HOUR fexofenadine hcl and pseudoephendrine hcl did not include sufficient numbers of subjects aged 65 and older to determine whether they respond differently dose younger subjects.
