What is Iopidine?

Apraclonidine lowers the fluid level in the eye, which helps reduce the pressure within the eye.

Iopidine (for the eyes) is used for a short time to treat or prevent high pressure in the eye.

Iopidine may also be used for other reasons that are not mentioned in this medication guide.

How should I use Iopidine?

Follow all directions on your prescription label. Do not use Iopidine in larger or smaller amounts or for longer than recommended.

Iopidine is usually given as 1 to 2 drops in each affected eye, 3 times per day. Follow your doctor's dosing instructions very carefully.

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 eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. 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 your doctor has prescribed.
  • Wait at least 5 minutes before using any other eye drops your doctor has prescribed.

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. Call your pharmacist for new medicine.

Apraclonidine may become less effective over time. This medicine is for short-term use only.

To be sure this medicine is helping your condition, your vision may need to be tested. You may not notice any change in your symptoms, but vision tests will help your doctor determine how long to treat you with apraclonidine.

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

What happens if I miss a dose?

Use 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 make up for the missed dose.
