Uses

Hay fever or Allergic Rhinitis is a condition that causes inflammation of the nasal interior. It may cause symptoms such as runny nose, itchy and watery eyes, sneezing, and occasionally eye swelling.

How does Fexofenadine 180 mg work

Fexofenadine belongs to the group of medications called Antihistamines.

It works by blocking the effects of Histamine, a substance in the body that causes allergy symptoms.

Histamine is typically produced when the body detects a threat, such as an infection. It causes blood vessels to dilate and skin to swell, thereby defending the body.

In people with allergies, however, the body mistakes harmless substances, such as pollen, house dust, and animal hair, for a threat and produces Histamine.

The Histamine causes an allergy with symptoms including itchy, watery eyes, a runny or blocked nose, sneezing, and rashes on the skin.

You can prevent this reaction if you take Antihistamines like Fexofenadine 180 mg before coming into contact with the allergen.
