Hhfexo 120mg Tablet contains Fexofenadine 120mg, a second-generation antihistamine used primarily for the relief of allergy symptoms. Fexofenadine is a selective peripheral H1-receptor antagonist that effectively reduces the effects of histamine, a natural substance responsible for allergic reactions. This medication is indicated for the treatment of seasonal allergic rhinitis, including symptoms such as sneezing, runny nose, itchy or watery eyes, and nasal congestion. Additionally, Hhfexo 120mg is used to manage chronic idiopathic urticaria, providing relief from itching and the appearance of hives. Unlike first-generation antihistamines, Fexofenadine does not readily cross the blood-brain barrier, minimizing sedative effects and allowing for daytime use without significant drowsiness. The recommended dosage for adults and children over 12 years is one tablet daily, taken with water, preferably on an empty stomach for optimal absorption. Patients with renal impairment should consult a healthcare professional for appropriate dose adjustments. Common side effects may include headache, nausea, and fatigue, though these are generally mild and transient. Hhfexo 120mg should be used under medical supervision, especially in individuals with known hypersensitivity to Fexofenadine or any of its excipients. It is important to inform the physician about any concurrent medications to avoid potential drug interactions.
