 Can TB disease be cured?

YES! Antibiotics have cured thousands of people with TB disease in Canada. The most common drugs used to fight TB are the following:

  • Isoniazid (INH)

Your doctor will determine the best antibiotics for you. Antibiotics must be taken for at least 6 months to kill all the TB bacteria. Taking more than one antibiotic at a time prevents drug-resistant TB.
