Chloramphenicol is an antibiotic useful for the treatment of a number of bacterial infections.[4] This includes use as an eye ointment to treat conjunctivitis.[5] By mouth or by injection into a vein, it is used to treat meningitis, plague, cholera, and typhoid fever.[4] Its use by mouth or by injection is only recommended when safer antibiotics cannot be used.[4] Monitoring both blood levels of the medication and blood cell levels every two days is recommended during treatment.[4]

Common side effects include bone marrow suppression, nausea, and diarrhea.[4] The bone marrow suppression may result in death.[4] To reduce the risk of side effects treatment duration should be as short as possible.[4] People with liver or kidney problems may need lower doses.[4] In young infants, a condition known as gray baby syndrome may occur which results in a swollen stomach and low blood pressure.[4] Its use near the end of pregnancy and during breastfeeding is typically not recommended.[6] Chloramphenicol is a broad-spectrum antibiotic that typically stops bacterial growth by stopping the production of proteins.[4]

Chloramphenicol was discovered after being isolated from Streptomyces venezuelae in 1947.[7] Its chemical structure was identified and it was first synthesized in 1949. It is on the World Health Organization's List of Essential Medicines.[8] It is available as a generic medication.[4]
