What is ETHAMBUTOL HCL?
(ETHAMBUTOL HCL) Ethambutol is used with other medications to treat tuberculosis (TB). Ethambutol is an antibiotic and works by stopping the growth of bacteria. This antibiotic treats only bacterial infections. It will not work for viral infections (such as common cold, flu). Using any antibiotic when it is not needed can cause it to not work for future infections.
How should I use ETHAMBUTOL HCL?
Take this medication by mouth with or without food as directed by your doctor, usually once daily. This medication may sometimes be taken twice weekly. Take this medication exactly as directed by your doctor. The dosage is based on your age, weight, medical condition, and response to treatment. If you also take antacids that contain aluminum, take this medication at least 4 hours before the antacid. For the best effect, take this antibiotic at evenly spaced times. To help you remember, take this medication at the same time(s) every day. Continue to take this medication (and other TB medications) until the full prescribed amount is finished, even if symptoms disappear. Stopping the medication too early or skipping doses may allow the bacteria to continue to grow, which may result in a return of the infection and cause the infection to be more difficult to treat (resistant). Tell your doctor if your condition lasts or gets worse.
