How to Use Cosopt:

- Your doctor will tell you how much of Cosopt to use and how often. Do not use more medicine or use it more often than your doctor tells you to.
- Wash your hands with soap and water before and after using Cosopt.
- Lie down or tilt your head back. With your index finger, pull down the lower lid of your eye to form a pocket.
- To use the eye drops: Hold the dropper close to your eye with the other hand. Drop the correct number of drops into the pocket made between your lower lid and eyeball. Gently close your eyes. Place your index finger over the inner corner of your eye for 1 minute. Do not rinse or wipe the dropper or allow it to touch anything, including your eye. Put the cap on the bottle right away. Keep the bottle upright when you are not using it.
- It is very important that you not allow the medicine dropper to touch anything, including your eye. If the dropper touches anything, germs may go into your eye and cause infection.

If a dose of Cosopt is missed:
- If you miss a dose or forget to use your medicine, use it as soon as you can. If it is almost time for your next dose, wait until then to use the medicine and skip the missed dose. Do not use extra medicine to make up for a missed dose.
How to Store and Dispose of Cosopt:
- Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light.
