Brand name(s)

This medication is used to treat bacterial infections (such as blepharitis, conjunctivitis) of the eye. It contains 2 antibiotics. Polymyxin B works by killing the bacteria. Trimethoprim works by stopping the growth of the bacteria.

This medication treats only bacterial eye infections. It will not work for other types of eye infections. Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.

Use this medication in the affected eye(s) as directed by your doctor, usually every 3 hours.

To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface. Use in the eyes only. Do not swallow or inject.

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

Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place one drop into the pouch as directed by your doctor. Look downward, gently close your eyes, and place one finger at the corner of your eye (near the nose). Apply gentle pressure for 1 to 2 minutes before opening your eyes. This will prevent the medication from draining out. Try not to blink or rub your eye. Repeat these steps if your dose is for more than one drop. If directed to use this medication in both eyes, repeat these steps for your other eye. Do not rinse the dropper. Replace the dropper cap after each use.

Dosage is based on your medical condition and response to treatment. Your doctor may direct you to use this medication more often at first, then use it less often as the infection improves. Follow your doctor's directions carefully.

Tell your doctor if you are using other eye products (such as drops, ointments, artificial tears). Some ingredients in these products may interact with this medication and prevent it from working. Ask your doctor or pharmacist if you can use these eye products while using this medication and how long to wait before applying the other products. Use eye drops before eye ointments to allow the 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. To help you remember, use it at the same times each day. 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.

Temporary eye stinging/burning/redness/itchiness or temporary blurred vision may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Use of this medication for prolonged or repeated periods may result in other types of eye infections, including fungal infections. Contact your doctor if you notice new eye symptoms (such as pain, swelling, thick discharge or pus).
