Ethambutol is a prescription medication used to treat tuberculosis (TB). Ethambutol belongs to a group
of drugs called antimycobacterial antibiotics. TB is caused by a certain bacteria. Ethambutol works by
stopping the bacteria from forming a cell wall, which kills the bacteria.
This medication comes in tablet form. It is taken once a day with or without food.
Common side effects of Ethambutol include loss of appetite, upset stomach, and numbness or tingling in
hands and feet.
Ethambutol is supplied as a tablet to be taken by mouth, usually once daily. This medication can be
taken with or without food. Try to take Ethambutol at the same time every day to get the most benefit.
Continue taking Ethambutol as directed by your doctor. Stopping the medicine too early may cause the
infection to be more difficult to treat.
If you take aluminum-containing antacids, take this Ethambutol at least 4 hours before the antacid.
Take Ethambutol exactly as prescribed by your doctor. Follow the directions on your prescription label
carefully. The dosage must be individualized. The dosage is based on your age, weight, medical
condition, and response to treatment.
