Optihist Eye Drop is used to treat allergic diseases of the eye.
It relieves redness and swelling of the eye and provides temporary relief from burning and discomfort.
Work mechanism:
Optihist Eye Drop is a combination of four medicines: Chlorpheniramine Maleate, Naphazoline, Zinc Sulphate Monohydrate and Boric Acid. Chlorpheniramine is an antiallergic which blocks the action of certain chemical messengers responsible for red, itchy, teary eyes. Naphazoline is a decongestant which narrows the blood vessels of the eye to relieve inflammation (redness and swelling). Zinc sulphate monohydrate and boric acid are antiseptics which treat bacterial infection in the eyes and relieve irritation.
