About Allegra 180(Fexofenadine 180mg) Tablet
What is Allegra 180(Fexofenadine 180mg) Tablet?
Allegra 180 (Fexofenadine 180mg) Tablet is a second-generation antihistamine used to manage symptoms of seasonal allergies and chronic skin conditions like hives. Unlike older antihistamines, it does not cross the blood-brain barrier significantly, minimizing drowsiness. It works by blocking histamine H1 receptors, reducing allergic responses such as nasal congestion, sneezing, itchy or watery eyes, and skin rashes. Fexofenadine is the active metabolite of terfenadine and offers fast, long-lasting relief for up to 24 hours with a single dose.

▾
Allegra 180mg is classified as a non-drowsy antihistamine. Most people do not experience sedation. However, individual responses vary. It’s generally safe for use while driving or working, but avoid alcohol, which may increase drowsiness risk.
How long does it take for Allegra to work?

Can I take Allegra with other medications?
