This combination is commonly used for:
• Active tuberculosis: Treats active TB infection by targeting the bacteria through multiple mechanisms.
• Treatment of pulmonary and extrapulmonary tuberculosis: Used as part of combination therapy for susceptible tuberculosis infections.
• Drug-resistant infection prevention: Combining multiple agents helps reduce the risk of the bacteria developing resistance to treatment.

Side effects of Ethambutol + Isoniazid + Rifampicin

  • Nausea and vomiting

  • Loss of appetite

  • Unusual tiredness or weakness

  • Dark urine

  • Yellowing of skin or eyes

How Ethambutol + Isoniazid + Rifampicin works

  • Ethambutol + Isoniazid + Rifampicin combines three antitubercular agents that attack the bacteria through different mechanisms.
  • Ethambutol inhibits the formation of the bacterial cell wall by interfering with arabinogalactan synthesis, hindering bacterial growth and multiplication.
  • Isoniazid prevents the bacteria from forming their protective cell wall by inhibiting mycolic acid synthesis.
  • Rifampicin blocks bacterial RNA polymerase, preventing RNA synthesis and bacterial multiplication.
    Together, these three medicines attack the tuberculosis bacteria at different points, making treatment more effective and reducing the chances of the bacteria developing resistance.
