Ethambutol is used to treat and prevent tuberculosis, a bacterial infection that primarily affects the lungs.
Ethambutol works by preventing the growth of TB bacteria. It targets and eliminates these bacteria, thus preventing their spread to other parts of the body or to other people.
Ethambutol is typically administered orally once daily. The recommended adult dosage is 15 mg/kg daily for those without prior tuberculosis treatment and 25 mg/kg daily for those with prior treatment. After 60 days at 25 mg/kg, the dose is reduced to 15 mg/kg.
Common side effects of Ethambutol include vision changes, nausea, or joint pain. Rare but serious effects include optic neuritis (vision damage).
Avoid Ethambutol if you're allergic to it, have severe kidney disease, or pre-existing vision problems. Also, it's not recommended for children under 13. Always inform your doctor about your medical conditions.
