Proper Use of This Medicine:

Shake the medicine well just before each use.

To use the eye drops (solution):

• Wash your hands with soap and water before and after you use this medicine.
• Tilt the head back. Press your finger gently on the skin just beneath the lower eyelid and 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.
• 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.

You should not use the eye drops if you have contact lenses in your eyes. Remove your contact lenses before you use this medicine. Wait at least 15 minutes after you use the medicine before putting the contact lenses back in.

If your doctor ordered two different eye medicines to be used together, wait several minutes before using the second medicine. This will help prevent the second medicine from “washing out” the first one.
