To use this medicine:

• Tilt your head back slightly and pull down your lower eyelid to create a small pocket.

• Eye drops: 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.

• Use only the number of drops your doctor has prescribed. If you use more than one drop, wait about 5 minutes between drops.

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

• Eye ointment: Hold the ointment tube with the tip pointing toward this pocket. Look up and away from the tip. Squeeze out a ribbon of ointment into the lower eyelid pocket without touching the tip of the tube to your eye. Blink your eye gently and then keep it closed for 1 or 2 minutes.

• Use a tissue to wipe excess ointment from your eyelashes.

• After opening your eyes, you may have blurred vision for a short time. Avoid driving or doing anything that requires you to be able to see clearly.

Do not touch the tip of the eye dropper or ointment tube. Do not place the tip directly on your eye. A contaminated dropper or tube 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 and heat. Do not freeze. Keep the bottle or tube tightly closed when not in use.
