MOKTEL DROP is a prescription eye drop that contains an antihistamine and a decongestant. It is used to relieve symptoms of allergic conjunctivitis, such as redness, itching, and watering of the eyes. The antihistamine works by blocking the action of histamine, a substance in the body that causes allergic symptoms. The decongestant works by constricting blood vessels in the eye, reducing redness and swelling. MOKTEL DROP should be used as directed by a healthcare provider and may cause temporary stinging or burning in the eyes.
