Cycloserine, sold under the brand name Seromycin, is a GABA transaminase inhibitor and an antibiotic, used to treat tuberculosis.[1][2] Specifically it is used, along with other antituberculosis medications, for active drug resistant tuberculosis.[2] It is given by mouth.[2]
Common side effects include allergic reactions, seizures, sleepiness, unsteadiness, and numbness.[2] It is not recommended in people who have kidney failure, epilepsy, depression, or are alcoholics.[2] It is unclear if use during pregnancy is safe for the baby.[2] Cycloserine is similar in structure to the amino acid D-alanine and works by interfering with the formation of the bacteria's cell wall.[2]
Cycloserine was discovered in 1954 from a type of Streptomyces.[3] It is on the World Health Organization's List of Essential Medicines.[4]
