Proper Use of Lastacaft
Your eye doctor will tell you how much of this medicine to use and how often. Do not use more medicine or use it more often than your doctor tells you to.
If you are using 2 or more eye drops, wait at least 5 minutes before putting another eye drop in the same eye.
If you are wearing contact lenses, remove them before putting the drops in your eyes. Wait at least 10 minutes after using this medicine before putting your contact lenses back in. Do not wear contact lenses if your eyes are red.
To use the eye drops:
- First, wash your hands. Then turn the closed bottle upside down and shake it one time before putting the medicine in your eye. Remove the cap with the bottle still being held upside down.
- Tilt your 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 eye. Do not blink. Keep the eye closed for 1 or 2 minutes to allow the medicine to cover the eye.
- If you think you did not get the drop of medicine into your eye properly, repeat the directions 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.
