Ethambutol 800mg

Ethambutol 800mg — Uses and Benefits

Ethambutol 800mg is used in the treatment of tuberculosis (TB), a bacterial infection that mainly affects the lungs but can also affect other parts of the body.

WHAT THIS MEDICINE IS USED FOR

• Treatment of active pulmonary and extrapulmonary tuberculosis
• Used in combination with other anti-TB drugs like isoniazid, rifampicin, and pyrazinamide
• Helps prevent TB bacteria from developing resistance to other drugs in the regimen

HOW IT WORKS

• Ethambutol stops TB bacteria from multiplying by interfering with the formation of their cell wall
• It does not kill the bacteria directly but stops their growth, allowing the immune system and other drugs to clear the infection
• It is effective only against actively growing bacteria

WHAT IT IS NOT USED FOR

• Not used alone to treat TB; always given in combination with other anti-TB medicines
• Not effective against viral or fungal infections
• Not used for latent (inactive) TB unless specifically advised by a doctor
• Not a painkiller or fever medicine
