Allegra Usage

Introduction
Allegra is a powerful, nauseating antihistamine that brings relief to the symptoms associated with seasonal allergic rhinitis in adults and children 6 years of age and older. Take Allegra-D on an empty stomach with water or you can also take regular Allegra with or without food. The symptoms that are treated effectively include sneezing, rhinorrhea, itchy nose/palate/throat, itchy/watery/red eyes. Allegra also comes handy in treatment of uncomplicated skin manifestations of chronic idiopathic urticaria in adults and children 6 years of age and older. It significantly reduces pruritus and the number of wheals. Allegra works by blocking the effect of histamine i.e. chemical in the body that causes the allergy symptoms. In case if you miss a dose take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Do not take two doses at once. Allegra needs to be kept at room temperature as well as protected from moisture.

Missed Dose
Do not double-up the allegra dose to make up for the missed one. If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take only your next regularly scheduled dose.

Overdosage
An excessive dose of any medicine can have serious consequences. Consult to a doctor whenever an overdose is suspected. However, symptoms of Allegra overdose may include dizziness, drowsiness, and dryness of mouth have been reported. Single doses of fexofenadine hydrochloride up to 800 mg, and doses up to 690 mg twice daily for 1 month or 240 mg once daily for 1 year were administered without the development of clinically significant adverse events as compared to placebo. In the event of overdose, consider standard measures to remove any unabsorbed drug. Symptomatic and supportive treatment is recommended. Hemodialysis did not effectively remove fexofenadine hydrochloride from blood following terfenadine administration.

No deaths occurred at oral doses of fexofenadine hydrochloride up to 5000 mg/kg in mice (110 times the maximum recommended daily oral dose in adults and 200 times the maximum recommended daily oral dose in children based on mg/m2) and up to 5000 mg/kg in rats (230 times the maximum recommended daily oral dose in adults and 400 times the maximum recommended daily oral dose in children based on mg/m2). Additionally, no clinical signs of toxicity or gross pathological findings were observed. In dogs, no evidence of toxicity was observed at oral doses up to 2000 mg/kg (300 times the maximum recommended daily oral dose in adults and 530 times the maximum recommended daily oral dose in children based on mg/m2.
