Uses For Iopidine

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

Apraclonidine 1% eye drops is used just before and after certain types of eye surgery (argon laser trabeculoplasty, argon laser iridotomy, and Nd:YAG laser posterior capsulotomy).

Apraclonidine 0.5% and 1% are available only with your doctor's prescription.

Proper Use of Iopidine

This medicine is available in 2 forms: apraclonidine 0.5% eye drops and apraclonidine 1% eye drops. Ask your doctor or pharmacist if you have any questions.

Apraclonidine 0.5% eye drops:

  • 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.
  • 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.
  • 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.

Apraclonidine 1% eye drops:

  • A doctor or other trained health professional will give you this medicine.
  • You will receive one drop of this medicine in the affected eye 1 hour before surgery, then one drop in the same eye immediately after surgery.
