Get Visine Online

Visine (tetrahydrozoline) is used to temporarily relieve redness in the eye caused by minor irritants such as smoke, dust, wind, chlorine from swimming pools, and other environmental exposures. It is not intended to treat underlying eye infections or chronic conditions.

Tetrahydrozoline is an alpha-adrenergic agonist. When applied as eye drops, it constricts the small blood vessels on the surface of the eye, reducing their visible redness within a few minutes of use.

Visine should be used no more than four times per day unless directed otherwise by your physician. Overuse, sometimes called the rebound effect, can actually worsen eye redness over time.

You should remove contact lenses before applying Visine eye drops. Wait at least 15 minutes after using the drops before reinserting your lenses. Some preservatives in eye drops can be absorbed by soft contact lenses.

Visine should be used with caution in people with narrow-angle glaucoma, high blood pressure, heart disease, or thyroid disorders. A physician will review your health history to ensure it is safe for you.

Common side effects include temporary stinging or burning upon application, brief blurred vision, and pupil dilation. Serious side effects are rare but may include increased heart rate or elevated blood pressure if absorbed systemically.
