GENERIC NAME: POLYMYXIN B/TRIMETHOPRIM - OPHTHALMIC (paw-lee-MIX-in B SUL-fate/try-METH-oh-prim)

BRAND NAME(S): Polytrim

Medication Uses | How To Use | Side Effects | Precautions | Drug Interactions | Overdose | Notes | Missed Dose | Storage

USES: This combination medication is used to treat certain bacterial infections of the eye(s) (e.g., conjunctivitis).

HOW TO USE: Place this medication in the affected eye(s) usually every 3 hours; or use as directed by your doctor. The number of drops (dosage) depends on your medical condition and response to therapy. 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. For best results, this medication must be used as directed. Continue using it for the full time prescribed. Stopping this medication too early may allow bacteria to continue to grow which may result in a relapse of the infection. If you are wearing contact lenses, remove them before using eye drops. Then tilt your head back, gaze upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over the eye and instill the prescribed number of drops. Look downward and gently close your eye for 1 to 2 minutes. Place one finger at the corner of the eye near the nose and apply gentle pressure. This will prevent the medication from draining away from the eye. Try not to blink and do not rub the eye. Do not rinse the dropper. Replace the dropper cap after each use. If you are using another kind of eye medication (e.g., drops or ointments), wait at least five minutes before applying any other medications. Use eye drops before eye ointments, to allow the eye drops to enter the eye.

SIDE EFFECTS: Eye redness, burning, stinging, or itchiness may occur. If any of these effects persist or worsen, notify your doctor promptly. Tell your doctor immediately if any of these serious side effects occurs: swelling in or around the eye, rash around the eyes. An allergic reaction to this product is unlikely, but seek immediate medical attention if it occurs. Symptoms of an allergic reaction include: dizziness, trouble breathing. Use of this medication for prolonged or repeated periods may result in a secondary infection (e.g., other bacteria or fungal infections). Contact your doctor if your notice any new symptoms or your condition worsens. If you notice other effects not listed above, contact your doctor or pharmacist.

What is the structure of the eye?

The eyes are complex sensory organs. About 85% of the total sensory input to our brains originates from our sense of sight, while the other 15% comes from the other four senses of hearing, smell, touch, and taste. The eyes are designed to optimize vision under conditions of varying light. Their location, on the outside of the face, makes them susceptible to trauma, environmental chemicals and particles, and infectious agents. The eyelids and the position of the eye within the bony orbital cavity are the major protective mechanism for the eye.

The eye itself has the shape of a sphere measuring about 1 inch in diameter. It consists of a clear, transparent dome at the front (the cornea) that is surrounded by the white of the eyeball (the sclera). The iris of the eye is the circular, colored portion within the eye, and behind the cornea, and the pupil is the central opening within the iris. Behind the iris and pupil is the e...
