fexofenadina

Fexofenadine is a second-generation antihistamine used to treat allergic rhinitis (hay fever) and chronic idiopathic urticaria (hives). It is a selective H1-receptor antagonist, meaning it blocks the action of histamine, a chemical released by the body during an allergic reaction. Unlike older antihistamines, fexofenadine is less likely to cause drowsiness because it does not readily cross the blood-brain barrier.

Fexofenadine is available over-the-counter and by prescription in various forms, including oral tablets, capsules, and liquid suspensions. It is typically taken once or twice daily. Common side effects are generally mild and can include headache, dizziness, and nausea. It is important to consult a healthcare professional before taking fexofenadine, especially if you have kidney or liver disease, or if you are pregnant or breastfeeding. Fexofenadine may interact with certain medications, such as antacids containing aluminum or magnesium, which can reduce its absorption. It is important to follow the dosage instructions on the product packaging or as prescribed by a doctor.
