Additional Information

Common side effects include kidney problems, hearing problems, poor balance, and pain at the site of injection. Other side effects include paralysis resulting in the inability to breathe. It is not recommended with streptomycin or other medications that may damage the auditory vestibular nerve. It is not recommended during pregnancy as it may cause kidney or hearing problems in the baby. Capreomycin is commonly grouped with the aminoglycoside family of medications. How it works is unclear.

Capreomycin was discovered from Streptomyces capreolus in 1960. It was removed from the World Health Organization's List of Essential Medicines in 2019.
