tetrahydrozoline ophthalmic (eye)
TETRAHYDROZOLINE - OPHTHALMIC
(TEH-truh-hi-DROZE-oh-leen)
COMMON BRAND NAME(S): Opti-Clear, Visine
USES: Tetrahydrozoline is a decongestant used to relieve redness in the eyes caused by minor eye irritations (such as smog, swimming, dust, or smoke). It belongs to a class of drugs known as sympathomimetic amines. It works by temporarily narrowing the blood vessels in the eye.Some brands of tetrahydrozoline eye drops may contain lubricants. Lubricants help protect the eyes from more irritation and dryness.
HOW TO USE: Follow all directions on the product package, or use as directed by your doctor. If you have any questions, ask your doctor or pharmacist.To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface. Remove contact lenses before applying the eye drops. Wait at least 10 minutes after using this medication before inserting contact lenses.Before using, check this product visually. Do not use if the liquid has changed color or is cloudy. Discard the medication away from children and pets.Use this medication in the affected eye(s) up to 4 times a day as needed or as directed by your doctor.Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over the eye and place 1 drop into the pouch. Look downward and gently close your eyes for 1 to 2 minutes. Place one finger at the corner of the eye near the nose and apply gentle pressure. This will prevent the medication from draining away from the eye. Try not to blink and do not rub the eye. Repeat these steps if your dose is for more than 1 drop and for the other eye if so directed.Do not rinse the dropper. Replace the dropper cap tightly after each use. If you are using another kind of eye medication (such as drops or ointments), wait at least 5 minutes before applying other medications. Use eye drops before eye ointments to allow the eye drops to enter the eye.Overuse of this type of medication may result in increased eye redness (rebound effect when drug wears off). If this occurs, tell your doctor.
