Uses For Iopidine

Apraclonidine 0.5% is used to treat glaucoma when the medications you have been using for glaucoma do not reduce your eye pressure enough.

Apraclonidine 1% is used just before and after certain types of eye surgery (argon laser trabeculoplasty, argon laser iridotomy, and Nd:YAG laser posterior capsulotomy). The medicine is used to control or prevent a rise in pressure within the eye (ocular hypertension) that can occur after this type of surgery.

In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.

Other Medical Problems

The presence of other medical problems may affect the use of this medicine. Make sure you tell your doctor if you have any other medical problems, especially:

  • Depression or
  • Heart or blood vessel disease or
  • High blood pressure—Apraclonidine may make the condition worse
  • Kidney disease or
  • Liver disease—Higher blood levels of apraclonidine may result, which may lead to increased side effects
  • Unusual reaction to a medicine that reduces the pressure within the eye—Apraclonidine is a strong reducer of eye pressure and could also cause this reaction
  • Vasovagal attack (history of)—The signs and symptoms are paleness, nausea, sweating, slow heartbeat, sudden and severe tiredness or weakness, and possibly fainting, usually brought on by emotional stress caused by fear or pain. Apraclonidine may cause this reaction to happen again

Proper Use of Iopidine

If your doctor ordered two different eye drops to be used together, wait at least 10 minutes between the times you apply the medicines. This will help to keep the second medicine from ''washing out'' the first one.

To use the eye drops:

  • First, wash your hands. Tilt the head back and, pressing your finger gently on the skin just beneath the lower eyelid, pull the lower eyelid away from the eye to make a space. Drop the medicine into this space. Let go of the eyelid and gently close the eyes. Do not blink. Keep the eyes closed and apply pressure to the inner corner of the eye with your finger for 1 or 2 minutes to allow the medicine to be absorbed by the eye.
  • If you think you did not get the drop of medicine into your eye properly, use another drop.
  • To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface (including the eye). Also, keep the container tightly closed.

Use this medicine only as directed. Do not use more of it and do not use it more often than your doctor ordered. To do so may increase the chance of too much medicine being absorbed into the body and the chance of side effects.

It is important that your doctor check your progress at regular visits. This is to make sure the medicine is working properly.

Dosing

The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
