General Information

The over-the-counter version of AK-Con-A (naphazoline ophthalmic) has been approved as a vasoconstrictor/antihistamine product for opthalmic use. Naphazoline ophthalmic causes decongestion in the eye by constricting blood vessels in the eye. It also enlarges the pupil, and it reduces the amount of fluid in the eye in two ways: It reduces the production of fluid inside the eye, and it increases the amount of fluid that drains from the eye. It is used to relieve redness, burning, irritation, and dryness of the eye caused by wind, sun, and other minor irritants.
