Antihistamine eye drops are a popular over-the-counter (OTC) and prescription remedy for treating allergic conjunctivitis and other forms of eye irritation caused by allergens. This guide will explain what antihistamine eye drops are, how they work, top brands, potential side effects, and when to see a doctor.
What Are Antihistamine Eye Drops?
Antihistamine eye drops are over-the-counter or prescription solutions that help relieve itchy, red, and watery eyes caused by allergens like pollen, dust mites, pet dander, and mold spores. They work by blocking histamines that trigger eye inflammation.
How Do Antihistamine Eye Drops Work?
When allergens contact the eyes, histamines are released, leading to redness, itchiness, and tearing. Antihistamine eye drops contain active ingredients like ketotifen or olopatadine that block histamine receptors in the eyes, relieving symptoms within minutes.
