Use this medication in the affected eye(s) as directed by your doctor, usually 3 times a day for the first 2 days and then 2 times a day for the next 5 days.

Do not wear contact lenses while you are using this medicine. Sterilize contact lenses according to manufacturer's directions and check with your doctor before using them.

To apply eye ointments, wash hands first. To avoid contamination, do not touch the tube tip or let it touch your eye or any other surface. Tilt your head back, look upward, and gently pull down the lower eyelid to make a pouch. Place a one-half inch (1.5-centimeters) strip of ointment into the pouch. Gently close the eye and roll the eyeball in all directions to spread the medication. Try not to blink or rub your eye. Repeat these steps for your other eye if so directed.

Wipe the tip of the ointment tube with a clean tissue to remove excess medication before recapping it.

If you are using another kind of eye medication (such as drops or other ointments), wait at least 5 minutes before applying other medications. Use eye drops before eye ointments to allow the eye drops to enter the eye.

Wait several minutes for your vision to clear before driving or operating machinery.

Use this medication regularly in order to get the most benefit from it. Continue to use this medication for the full time prescribed, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection.

Tell your doctor if your condition lasts or gets worse.
