Quick overview

Combutol Tablet contains Ethambutol, an antitubercular medicine used to treat tuberculosis (TB), a bacterial infection that mainly affects the lungs but can spread to other organs like the kidneys, spine, and brain. It is usually taken along with other TB medicines as part of a full treatment plan. Combutol works by blocking the bacteria from building their protective cell wall, helping stop the infection from growing and spreading.

What is Combutol Tablet

Combutol is a prescription antibiotic medicine used to treat tuberculosis (TB), a bacterial infection that mainly affects the lungs but can spread to other organs like the kidneys, spine, and brain. It contains the active ingredient Ethambutol and is usually taken along with other TB medicines.

Combutol Tablet uses

  • Treats active tuberculosis (TB), including infection of the lungs and other organs like the kidneys and spine
  • Helps stop the growth and spread of TB-causing bacteria
  • Used together with other anti-TB medicines to make treatment more effective and lower the chance of drug resistance

Benefits of Combutol Tablet

  • Can be easily combined with other anti-TB drugs to improve overall treatment effectiveness
  • Helps reduce the risk of the bacteria becoming resistant to treatment
  • Reliable, affordable, and simple to take, which is important where TB is a common health problem

How Combutol Tablet works

Ethambutol gets into the TB bacteria and blocks them from building their cell wall. This weakens the bacteria's protective outer layer so they cannot grow, multiply, or spread, which helps the immune system clear the infection.

Combutol Tablet dosage

Take this medicine by mouth, usually once a day, at the same time each day. You may take it with or without food, based on your doctor's advice. Swallow the tablet whole with water; do not break or chew it. If you take aluminum-containing antacids, take this medicine at least 4 hours before the antacid.

This medicine is usually given together with other TB medicines as part of a full treatment plan. Take the full course exactly as your doctor prescribes, even if you start feeling better, to prevent the infection from coming back or becoming drug-resistant. This medicine is not recommended for children under 13 years of age.
