Uses

What is Epinastine used for?

Epinastine is commonly used to prevent itching of the eyes caused by allergies (allergic conjunctivitis).

How should I take Epinastine?

This medication is used in both eyes, usually twice daily; or as directed by your doctor. Use should continue during times when you may be exposed to the agents (e.g., allergens, pollens) that can cause allergic conjunctivitis, even if your eyes are not irritated or itchy.

If you wear contact lenses, remove them before applying this medication. Wait at least 10 minutes after using the drops before wearing your lenses again.

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.

Tilt your head back, look upward and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and instill the prescribed number of drops. Look downward and gently close your eye for 1 to 2 minutes. Place one finger at the inside corner of the eye and apply gentle pressure to prevent the medication from draining out. Try not to blink and do not rub your eye.

Do not rinse the dropper. Replace the dropper cap after each use.

If you are using another kind of eye medication (e.g., drops or ointments), wait at least 10 minutes before applying other medications. Use eye drops before eye ointments to allow the eye drops to enter the eye.
