Lcfex 180 Tablet contains Fexofenadine 180 mg, a second-generation antihistamine used primarily for the relief of allergy symptoms. It is indicated for the treatment of seasonal allergic rhinitis, including symptoms such as sneezing, nasal congestion, runny nose, and itchy or watery eyes. Additionally, Lcfex 180 is effective in managing chronic idiopathic urticaria, providing relief from hives and associated itching. Fexofenadine works by selectively antagonizing peripheral histamine H1-receptors, thereby inhibiting the action of histamine, a key mediator in allergic reactions. Due to its minimal penetration of the blood-brain barrier, Fexofenadine is less likely to cause sedation compared to first-generation antihistamines, making it suitable for patients requiring daytime symptom control without drowsiness. The recommended dose for adults and children over 12 years is one tablet daily, preferably taken with water and on an empty stomach for optimal absorption. Lcfex 180 should be used with caution in patients with renal impairment, and dosage adjustments may be necessary. Common side effects are generally mild and may include headache, dizziness, and nausea. Patients should consult a healthcare professional before use, especially if pregnant, breastfeeding, or taking other medications to avoid potential interactions.
