Ostifen: A Comprehensive Guide to the Essential Antihistamine

Introduction

Ostifen (Pataday) is a topical ophthalmic antihistamine used to treat allergic conjunctivitis, commonly known as pink eye. This condition arises when the thin membrane that covers the white part of the eye (conjunctiva) becomes inflamed due to an allergic reaction to substances like pollen, dust, or pet dander. Ostifen effectively alleviates the uncomfortable symptoms associated with allergic conjunctivitis, providing rapid and prolonged relief.

Key Facts about Ostifen

How Ostifen Works

Ostifen belongs to a group of medications called antihistamines. These drugs work by blocking the effects of histamine, a chemical released by the body's immune system in response to allergens. Histamine causes the blood vessels in the eyes to dilate and fluid to leak out, resulting in redness, itching, and tearing. By blocking histamine, Ostifen reduces inflammation and relieves these bothersome symptoms.
