How Olopatadine HCl Helps Relieve Eye Allergies
Eye allergies (also called allergic conjunctivitis) are one of the most common eye problems, and they are becoming more common each year as seasonal allergies, in general, get worse. Symptoms of eye allergies include eye itching, redness, tearing, and eyelid swelling. Studies have shown that olopatadine hydrochloride (HCl) offers quick and effective relief of these allergy symptoms.
Originally, olopatadine HCl, an active ingredient used to treat eye allergies, was only available as prescription eye drops. Now, it’s available as over-the-counter eye drops that you can buy at local stores, where other seasonal allergy treatments are sold.
How Does Olopatadine HCl Work?
Olopatadine HCl is an antihistamine that was approved by the U.S. FDA in 1996 to treat eye allergy/allergic conjunctivitis symptoms and is the top doctor-prescribed allergy itch relief ingredient. Typically, when you are allergic to something and come into contact with it—for example, pollen—your immune system reacts and releases natural chemicals in your body called histamines. These chemicals are what cause redness, itching, swelling, etc. An antihistamine, therefore, blocks the histamine and prevents and relieves those allergy symptoms.
Olopatadine HCl works to relieve eye itching and redness caused by pollen, grass, ragweed, and pet dander. In many studies, olopatadine HCl proved to be better at relieving eye itchiness than other remedies and was found to be more comfortable than other topical and oral antihistamine solutions.
