Myambutol is an antibiotic and works by stopping the growth of bacteria. It is used with other medications to treat tuberculosis. This antibiotic treats only bacterial infections. It will not work for viral infections (such as common cold, flu). This drug may also be used with other medications to help treat a certain serious infection (Mycobacterium avium complex-MAC). It may also be used with other medications to prevent the MAC infection from occurring again in people with advanced HIV disease.
Take Myambutol exactly as prescribed by your doctor. Take each dose by mouth with a full glass of water, usually once daily. This medication may sometimes be taken twice weekly. It can be taken with or without food. Taking ethambutol with food may decrease stomach upset. Myambutol is usually combined with one or more other tuberculosis medicines. If you also take antacids that contain aluminum, take this medication at least 4 hours before the antacid.
Before taking Myambutol you should talk with your doctor if you have cataracts, diabetic retinopathy, optic neuritis, liver disease, kidney disease. Avoid alcoholic beverages. Alcohol may increase the risk of liver disease. Do not drive or perform tasks that require alertness.
Do not take Myambutol if you are pregnant or breastfeeding, or allergic to ethambutol.
