Answer: Doctors will still use other drugs that are known to treat tuberculosis, even if they are less effective than the common drugs.
Tuberculosis (TB) is a disease caused by bacteria that are spread through the air from one person to another. TB affects not just the lungs, but other parts of the body (the brain, the kidneys, or the spine). In most cases, TB is treatable and curable; however, sometimes drug-resistant tuberculosis occurs when the drug can no longer kill the TB bacteria. In such case, doctors will use other drugs that are known to treat TB, even if they are less effective than the commonly available drugs.
