Summary
Olopatadine is used to treat eye allergy symptoms like itching and redness. It is effective for allergic conjunctivitis, which is inflammation of the eye's outer layer caused by allergens like pollen or pet dander.
Olopatadine works by blocking histamines, which are chemicals in the body that cause allergy symptoms. This action reduces inflammation and provides relief from eye discomfort.
Olopatadine is usually administered as an eye drop. The typical dose for adults and children over 3 years old is one drop in each affected eye once or twice daily, as directed by a doctor.
Common adverse effects of olopatadine include mild eye irritation, burning, or stinging. These effects are usually temporary and resolve on their own.
Avoid using olopatadine if allergic to its ingredients. Do not use while wearing contact lenses; wait at least 10 minutes after application. If eye irritation or swelling occurs, stop use and contact a doctor.
