How do I use it?

Wash your hands thoroughly before applying medicine to your eyes. Tilt your head back and look up. Gently pull your lower eyelid down to form a pouch.

If you have the eyedrops, shake the bottle before you use the drops. Look up and squeeze a drop of the medicine into the pouch. Close your eyes for a minute or two and with a fingertip press gently on the inside corner of your eye to keep the medicine from draining out. Do not rub your eyes.

If you have the ointment, hold the tube in your hand for a minute or two to warm the medicine so it will flow easily from the tube. When you open the tube for the first time, squeeze out a little of the medicine and throw it away because it may be dry. Pull your lower eyelid down to form a pouch. Look up, and squeeze a 1/4-inch to 1/2-inch ribbon into the pouch. Close your eyes and roll them in all directions to spread the ointment around. Do not rub your eyes.

To keep from contaminating the medicine, do not let the tip of the container touch your eye or any other surface. After use, put the cap on tightly. Do not use eye medicine that has become discolored.

Your vision will be blurred for a little while after you use the ointment. Avoid driving and activities that require good vision until you can see clearly.

Use this medicine exactly as directed by your healthcare provider. Do not use it more often or longer than directed. Using too much can lead to other infections caused by bacteria that are resistant to this medicine.

If you miss a dose, use it as soon as you remember unless it is almost time for the next scheduled dose. In that case, skip the missed dose and use the next one as directed. Do not use double doses. If you are not sure of what to do if you miss a dose, or if you miss more than one dose, contact your healthcare provider.

What should I watch out for?
