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. Missing doses or not completing the full course of therapy may decrease the effectiveness of Myambutol and increase the risk that the bacteria will no longer be sensitive to Myambutol and will not be able to be treated by this or other antibiotics in the future.

Your doctor may adjust the dose depending on your response to therapy. Take this medication exactly as prescribed by your doctor.
