Polymyxin B+chloramphenicol
About Polymyxin B+chloramphenicol
Chloramphenicol+polymyxin B belongs to a combination of medicines called 'antibiotics,' primarily used to treat bacterial infections of the eye. Bacterial eye infection occurs when harmful bacteria enter any part of the eyeball or surrounding tissues, including the cornea (front surface of the eye) and the lining of the outer eye and inner eyelids (conjunctiva).
Chloramphenicol+polymyxin B is a combination of two antibiotics, namely: Polymyxin B and Chloramphenicol. Polymyxin B is bactericidal, killing bacteria by preventing the formation of bacterial cell walls, which are essential for their survival. Chloramphenicol is bacteriostatic, which prevents bacterial growth by inhibiting the production of essential proteins necessary for bacterial growth and multiplication. Chloramphenicol+polymyxin B prevents the spread of eye infections caused by a wide range of gram-negative bacteria.
Use Chloramphenicol+polymyxin B as prescribed by your doctor. This medicine is intended for use in the eyes only. Do not swallow or inject Chloramphenicol+polymyxin B. You are advised to use this medicine for as long as your doctor has prescribed it based on your medical condition. In some cases, you may experience redness, itching, irritation, burning/stinging sensations in the eyes, blurred vision, sensitivity to light, eyelid swelling, itching, or crusting as side effects. Most of these side effects of Chloramphenicol+polymyxin B do not require medical attention and typically resolve on their own over time. However, if any of these side effects worsen or persist, please consult your doctor.
If you are allergic to Chloramphenicol+polymyxin B or any other medicines, please inform your doctor. Chloramphenicol+polymyxin B should be used with caution in children. Consult your doctor if you are pregnant or breastfeeding before using Chloramphenicol+polymyxin B. You are recommended not to use contact lenses during the course of Chloramphenicol+polymyxin B as it may worsen the infection. If you experience any new eye problems, an eye infection, or notice any allergic reactions such as itching, redness of the eye, or a skin rash, please consult your doctor immediately. You are advised to maintain a 10-minute time gap between using Chloramphenicol+polymyxin B and other eye drops. Please do not contact the container tip to the eye, eyelids, or surrounding areas, as it may contaminate Chloramphenicol+polymyxin B and cause eye infections.
Uses of Polymyxin B+chloramphenicol
• Bacterial Conjunctivitis: Chloramphenicol+polymyxin B is commonly used to treat conjunctivitis (pink eye) caused by bacterial infections.

Medicinal Benefits
Chloramphenicol+polymyxin B is a combination of two antibiotics: Polymyxin B and Chloramphenicol. It is used to treat bacterial infections of the eye, like conjunctivitis. Polymyxin B is bactericidal (kills bacteria) in nature, inhibiting bacterial cell wall formation required for their survival. Thus, it prevents the entry of unwanted substances into the cells and stops the leakage of cell contents. Chloramphenicol is bacteriostatic (prevents bacterial growth) in nature, with excellent eye penetration, and exhibits broad-spectrum coverage against various bacteria that cause eye infections by inhibiting the protein synthesis process required for bacterial survival.
Directions for Use
- Chloramphenicol+polymyxin B is for ophthalmic (for eye) use only.
- It is recommended to instil 1-2 drops of Chloramphenicol+polymyxin B, 2-3 times daily, or as advised by your doctor.

Bacterial eye infections: Bacterial eye infections occur when harmful bacteria enter any part of the eyeball or surrounding tissues, including the cornea (front surface of the eye) and the lining of the outer eye and inner eyelids (conjunctiva). The common symptoms of eye infections are red eyes, pain, discharge, watery eyes, dry eyes, light sensitivity, swollen eyes, itching, and blurred vision. Conjunctivitis (pink eye) is the infection/inflammation of the conjunctiva (white part of the eye) and the inner eyelid. Keratitis is the inflammation of the cornea. It is a common issue among individuals who wear contact lenses.
FAQs
Chloramphenicol+polymyxin B is used to treat bacterial infections of the eye (optic).
Chloramphenicol+polymyxin B contains Polymyxin B and Chloramphenicol. Polymyxin B works by inhibiting the formation of bacterial cell walls, which are necessary for survival because they prevent unwanted substances from entering the cells and stop the leakage of cell contents. Chloramphenicol inhibits the production of essential proteins required for bacterial growth and multiplication. Bacteria are thus destroyed. They work together to relieve itching, pain, and discomfort in the eye caused by infection.
