Why is this medication prescribed?   Return to top

Neomycin, polymyxin, and bacitracin combination is used to treat eye and eyelid infections. Neomycin, polymyxin, and bacitracin are in a class of medications called antibiotics. Neomycin, polymyxin, and bacitracin combination works by stopping the growth of bacteria infecting a surface of the eye.

How should this medicine be used?   Return to top

Neomycin, polymyxin, and bacitracin combination comes as an ophthalmic ointment to apply inside the lower lid of an infected eye. The ointment is usually applied to the eye every 3-4 hours for 7-10 days, as directed by your doctor. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use neomycin, polymyxin, and bacitracin ophthalmic ointment exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Your eye or eyelid infection should begin getting better during the first few days of treatment with neomycin, polymyxin, and bacitracin combination. If your symptoms do not go away or get worse, call your doctor.

Continue to use neomycin, polymyxin, and bacitracin combination as directed, even if your symptoms improve. Do not stop using neomycin, polymyxin, and bacitracin combination without talking to your doctor. If you stop using this medication too soon or skip doses, your infection may not be completely cured and bacteria may become resistant to antibiotics.

This medication is for use in the eye only. Do not let neomycin, polymyxin, and bacitracin combination get into your nose or mouth, and do not swallow it.

Never share your tube of ophthalmic ointment, even with someone who was also prescribed this medication. If more than one person uses the same tube, infection may spread.

To use the eye ointment, follow these steps:

• Wash your hands well with soap and water.
• Use a mirror or have someone else apply the ointment.
• The ointment must be kept clean. Do not touch the tip of the tube against your eye, eyelid, fingers, or anything else.
• Lie down and gaze upward or tilt your head back while standing.
• Hold the tube between your thumb and index finger of the hand you usually use to hold a pencil. Place the tube as near to your eyelid as possible without touching it.
• Brace the remaining fingers of your hand against your cheek or nose.
• With the index finger of your other hand, pull the lower lid of your eye down to form a pocket.
• Place the prescribed amount of ointment into the pocket made by your lower lid and eye.
• Replace and tighten the cap right away.
• Gently close your eyes and keep them closed for 1-2 minutes to allow the medication in the ointment to be absorbed.
• Wipe off any excess ointment from outside or below your eye with a clean tissue. Wipe off any excess ointment from the outside of the tube with a clean tissue. Wash your hands again to remove any ointment.
