Tetrahydrozoline causes constriction (narrowing) of blood vessels in the eyes. It also decreases itching and irritation of the eyes. Zinc is used as an astringent to gently clear proteins and mucus from the outer surface of the eye. The combination of tetrahydrozoline and zinc ophthalmic (for the eyes) is used to relieve eye redness, burning, irritation, and itching caused by airborne irritants such as pollen, dust, and ragweed. Tetrahydrozoline and zinc ophthalmic may also be used for other purposes not listed in this medication guide.
