Fexofenadine is used to relieve allergy symptoms associated with seasonal allergic rhinitis like runny nose, sneezing and itchy eyes. It is also used to treat chronic urticaria, which includes symptoms like hives and itching.
Fexofenadine works by blocking the effects of histamine, a substance in the body that causes allergy symptoms. By preventing histamine from binding to its receptors, it reduces symptoms like sneezing, runny nose and itchy eyes.
For adults and children 12 years and older, the usual dose is 180 mg once daily or 60 mg twice daily. For children aged 2 to under 12 years, the dose is 5 mL of the suspension every 12 hours. Always follow your doctor's advice for the correct dosage.
Common side effects of Fexofenadine include headache, dizziness, diarrhea, and fatigue. Serious side effects, though rare, include difficulty breathing, swelling and severe allergic reactions.
