Opcon-A Naphazoline (decongestant)/ Pheniramine(antihistamine) ophthalmic solution is a combination product containing two active ingredients. Naphazoline (naf-AZ-oh-leen) is used to relieve redness due to minor eye irritations, such as those caused by colds, dust, wind, smog, pollen, swimming, or wearing contact lenses. Remove contact lenses before using. Pheniramine (fen-EER-a-meen) is an antihistaminic ophthalmic solution that is used in the eye to treat symptoms caused by allergies. It works by acting on certain cells in the eye, called mast cells, to prevent them from releasing substances that cause the allergic reaction. Use this medicine only as directed. Do not use more of it, do not use it more often, and do not use it for more than 72 hours, unless otherwise directed by your doctor. To do so may make your eye redness and irritation worse; this may also increase the chance of side effects.
