What is epinastine ophthalmic?

Epinastine is an antihistamine that helps lessen the effects of a natural chemical called histamine in the body. Histamine can cause symptoms like sneezing, itching, watery eyes, and a runny nose.

Epinastine ophthalmic (for the eyes) is used to prevent itching of the eyes due to allergies.

Epinastine ophthalmic should not be used to treat eye irritation or discomfort from wearing contact lenses.

Epinastine ophthalmic may also be used for other reasons not mentioned in this medication guide.

How should I use epinastine ophthalmic?

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

This medication is usually used only for a short time until allergy season ends.

Epinastine ophthalmic is usually used twice per day. Follow your doctor's instructions.

Wash your hands before using eye medication.

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 as you squeeze out a drop, then close your eye.
  • Use only the number of drops your doctor has prescribed.
  • Gently press your finger to the inside corner of the eye (near your nose) for about 1 minute to keep the liquid from draining into your tear duct.
  • If you use more than one drop in the same eye, wait about 5 minutes before putting in the next drop.
  • Also wait at least 10 minutes before using any other eye drops that your doctor has prescribed.

Do not allow the tip of the dropper to touch any surface, including your eyes or hands. If the dropper becomes contaminated, it could cause an infection in your eye, which can lead to vision loss or serious damage to the eye.

Do not use the eye drops if the liquid has changed colors or has particles in it. Call your doctor for a new prescription.

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