Use this medication to the eye(s) as directed by your doctor, usually every 3 or 4 hours.

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 you begin using them again.

To apply the eye ointment, wash your 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 pull down the lower eyelid to make a pouch. Place a 1/2 inch (1.5 centimeters) strip of ointment into the pouch by squeezing the tube gently. Close the eye and roll the eyeball in all directions to spread the medication. Try not to blink and do not rub the 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. Apply as often as directed by your doctor.

If you are using another kind of eye medication (such as drops or ointments), apply the eye drops first and wait at least 5 minutes before applying this eye ointment. Use eye drops before eye ointments to allow the eye drops to enter the eye. If you are using another type of eye ointment, wait at least 10 minutes after using this medication before applying it.

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