Chloramphenicol is a broad-spectrum antibiotic used to treat serious bacterial infections and certain eye infections.
It is commonly used for:
• Bacterial conjunctivitis: Treats bacterial eye infections causing redness, discharge, and irritation.
• Typhoid fever: Used to treat infections caused by Salmonella typhi in certain settings.
• Meningitis: Used for bacterial infection of the membranes surrounding the brain and spinal cord when other antibiotics are unsuitable.
• Serious systemic infections: Reserved for severe infections where other antibiotics have failed or cannot be used.
• Ear infections: Available as drops to treat bacterial infections of the outer ear.

Chloramphenicol works by stopping bacteria from producing the proteins they need to grow and multiply.
It binds to a part of the bacterial ribosome, the structure responsible for building proteins, and blocks this process.
Without the ability to produce new proteins, bacteria cannot grow or repair themselves, which allows the infection to be brought under control. Because of its potential for serious side effects, chloramphenicol is generally reserved for infections that cannot be treated with safer alternatives, or used topically for eye and ear infections.
