To apply the eye drops:
Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye with the tip down. Look up and away from the dropper and squeeze out a drop.
Close your eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.
Wait at least 10 minutes before using any other eye drops your doctor has prescribed.
Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.
Do not use the eye drops if the liquid has changed colors or has particles in it. Call your pharmacist for new medicine.
Store at room temperature away from moisture, heat, and light. Do not freeze. Keep the bottle tightly closed when not in use.
Use this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics.
Call your doctor if your symptoms do not improve after 7 to 10 days of treatment, or if you have a fever with a headache, cough, or skin rash.
