Proper use of pilocarpine
Use this medicine only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time 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.
To use the eye drops:
- Wash your hands with soap and water before and after using this medicine.
- Tilt your head back and, pressing your finger gently on the skin just beneath the lower eyelid, pull the eyelid away from the eye to make a space. Drop the medicine into this space.
- Let go of the eyelid and gently close the eye. Do not blink. Keep the eye closed 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, repeat the process with 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. Serious damage to the eye and possible loss of vision may result from using contaminated eye medicines.
To use the eye gel:
- 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. Squeeze a thin strip of gel into this space. A 1½-cm (approximately ½-inch) strip of gel is usually enough, unless you have been told by your doctor to use a different amount. Let go of the eyelid and gently close the eyes. Keep the eyes closed for 1 or 2 minutes to allow the medicine to be absorbed by the eye.
- Immediately after using the eye gel, wash your hands to remove any medicine that may be on them.
- To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface (including the eye). After using the eye gel, wipe the tip of the gel tube with a clean tissue and keep the tube tightly closed.
To use the eye insert:
- This medicine usually comes with patient directions. Read them carefully before using this medicine.
- If you think this medicine unit may be damaged, do not use it. If you have any questions about this, check with your health care professional.
