Table of contents:

Myambutol (generically known as ethambutol) is an antibiotic that is used to treat tuberculosis (TB) and other bacterial infections. It is sometimes prescribed in combination with other antibiotics to treat TB and may be used for other purposes as well.

Ethambutol belongs to the group of drugs called antimycobacterial antibiotics. It works by inhibiting RNA synthesis and bacterial replication, which stops TB bacteria from making the building blocks they need to multiply and survive.

Myambutol is used to treat tuberculosis (TB) and is usually given together with at least one other tuberculosis medicine. It should not be used as the sole antituberculous drug, but rather in conjunction with other TB medications.

Use and Dosage

Myambutol comes as a tablet medication that is taken orally with or without food as directed by your doctor, usually once daily. In some cases, the tablet may be taken twice weekly. Follow your doctor's instructions precisely, and the dosage will depend on several factors such as age, weight, medical condition, and response to treatment.

If you take antacids that contain aluminum, you should take Myambutol at least four hours before taking the antacid to avoid any negative interactions.

To ensure the best results, take this medication at even intervals throughout the day. You can keep track of your dosage by taking the medication at the same time(s) every day.

Continue taking Myambutol (and any other TB medication you've been prescribed) until the full prescribed amount is finished, even if your symptoms disappear. Stopping the medication too early or skipping doses may allow the bacteria to continue to grow, which can lead to a return of the infection and can make it more challenging to treat (resistant).
