How Allegra 120mg Tablet Works: Uses, Benefits & Side Effects

Allegra 120mg Tablet can be a major nuisance, causing sneezing, itching, runny nose, and other discomforts. Allegra 120mg is a widely used antihistamine that provides relief from allergic reactions without causing drowsiness. But how does it work, and is it the right choice for you? In this blog, we’ll explore how Allegra 120mg functions, its common uses, benefits, and possible side effects.

How Allegra 120mg Works

Allegra 120mg contains fexofenadine hydrochloride, an antihistamine that blocks histamine receptors (H1 receptors) in the body. Histamine is a natural substance released by the immune system in response to allergens, leading to symptoms like itching, swelling, and congestion. By preventing histamine from binding to its receptors, Allegra helps reduce these allergic symptoms effectively.

Unlike first-generation antihistamines, Allegra does not cross the blood-brain barrier significantly, meaning it does not cause drowsiness, making it a preferred option for many allergy sufferers.
