• Use only the number of drops your doctor has prescribed.

• Gently press your finger to the inside corner of the eye (near your nose) for about 1 minute to keep the liquid from draining into your tear duct.

• If you use more than one drop in the same eye, wait about 5 minutes before putting in the next drop.

• Also wait at least 10 minutes before using any other eye drops that your doctor has prescribed.
