    • How to use Eye Cool

    Do not use if the solution turns brown or becomes cloudy.

    To use:

  • 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 2 or 3 minutes to allow the medicine to be absorbed by the eye.
  • Immediately after using the eye drops, 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). Also, keep the container tightly closed.

    • For patients using the 2.5 or 10% eye drops:

  • It is very important that you 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. This is especially important when this medicine is used in children or in patients with heart disease or high blood pressure, since high doses of this medicine may cause an irregular heartbeat and an increase in blood pressure.
