Myambutol (ethambutol) is an antibiotic used to treat tuberculosis (TB). It is used in combination with other drugs to treat tuberculosis caused by Mycobacterium tuberculosis. It works by stopping the growth of the bacteria that cause TB. Myambutol is available in tablets and as an oral suspension.
Common Use
Myambutol is used to treat active tuberculosis. It is usually used in combination with other drugs. It should be taken with food or milk to reduce stomach upset. It is important to take the entire course of medication even if you feel better.
