fexofenadiin

Fexofenadine is a second-generation antihistamine used to treat allergy symptoms. It is the active metabolite of terfenadine, a drug that was withdrawn from the market due to cardiac side effects. Fexofenadine works by blocking the action of histamine, a chemical released by the body during an allergic reaction. This blockage reduces symptoms such as sneezing, runny nose, itchy or watery eyes, and itching of the nose or throat.

Fexofenadine is available over-the-counter and by prescription in various formulations, including tablets, capsules, and liquid suspensions. It is commonly used to manage seasonal allergic rhinitis, also known as hay fever, and chronic idiopathic urticaria, a type of hives. It is generally considered to have a favorable safety profile, with a low incidence of drowsiness compared to first-generation antihistamines.

Common side effects of fexofenadine are typically mild and may include headache, nausea, and dizziness. It is important to take fexofenadine as directed by a healthcare professional or the product label. It is generally not recommended for use in children under the age of 6 without medical advice. Fexofenadine is not known to interact significantly with alcohol. It is important to consult a doctor or pharmacist if you have any pre-existing medical conditions or are taking other medications.
