Aller Nil O Eye Drop belongs to the 'antihistamine' class of drugs, primarily used to treat signs and symptoms of seasonal allergic conjunctivitis. Aller Nil O Eye Drop is also used to treat eye itching or redness caused by pollen, ragweed, grass, animal hair, or dander. Allergic conjunctivitis is an inflammation of the conjunctiva (the clear tissue that covers the white part of the eye and the inside of the eyelids) caused by an allergic reaction.
Aller Nil O Eye Drop contains Olopatadine, which inhibits the release of histamine (chemical messengers released due to an allergic response in the body) from mast cells. Thereby relieves itching, burning, redness, and watering in the eyes caused by allergic conjunctivitis.
