Opti-Clear

Tetrahydrozoline is a vasoconstrictor. It works by narrowing swollen blood vessels in the eyes to reduce eye redness.

Opti-Clear (for the eyes) is used for temporary relief of minor eye redness, swelling, or draining caused by minor irritants.

Opti-Clear may also be used for purposes not listed in this medication guide.

Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Using the medication too long or too often may worsen your symptoms and cause damage to the blood vessels in your eyes.

Wash your hands before using the eye drops.

To apply the eye drops:

• Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye with the tip down. Look up and away from the dropper and squeeze out a drop.
• Close your eye and gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.
• Use only the number of drops recommended.

Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.

Do not use the eye drops if the liquid has changed colors or has particles in it.

Store at room temperature away from moisture and heat. Do not freeze. Keep the bottle tightly closed when not in use.

Opti-Clear is for temporary relief of minor eye redness or discomfort caused by minor irritants.

Since Opti-Clear is used as needed, you might not have a dosing schedule. If you do have a schedule, take the missed dose as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose. Do not use extra medicine to compensate for the missed dose.

An overdose of tetrahydrozoline ophthalmic is not expected to be dangerous. Seek emergency medical help or call the Poison Help line at 1-800-222-1222 if anyone has accidentally swallowed the medication.

Keep Opti-Clear out of the reach of children. Some eye medications can cause serious health issues in a young child who accidentally sucks on or swallows medicine from the eye dropper.

Do not use this medication while wearing contact lenses. Opti-Clear may contain a preservative that can discolor soft contact lenses. Wait at least 15 minutes after using this medicine before putting in your contact lenses.

It is not likely that other drugs you take by mouth or inject will affect tetrahydrozoline ophthalmic used in the eyes. However, many drugs can interact with each other. Inform each of your healthcare providers about all medicines you use, including prescription and over-the-counter medicines, vitamins, and herbal products.
