Oculast Eye Drops 5ml

Azelastine is an antihistamine; it helps relieve allergic itchiness by blocking the release of a chemical called histamine, which is produced by the body as part of an allergic reaction. Allergic conjunctivitis causes red, watery, itchy eyes. It is caused by exposure to irritants such as plant pollens, pet fur, cosmetics or house dust mite. Seasonal allergic conjunctivitis occurs at certain times in a year, a common cause being an allergy to pollen in the hay fever season. Perennial allergic conjunctivitis persists throughout the year. This is commonly due to an allergy to house dust mite or animal hair.
