Hello, you need to follow your doctor's prescription strictly and you can't stop taking medicine until you're told to. Treating TB takes much longer than treating other infections, patients need to take antibiotics for six to nine months. Latest research proposed 4 months drug treatment, which you can discuss with your doctor. But please do not stop medicine without discussing with your doctor, it's risky.

If you have latent tuberculosis, you may need to take only one or two types of TB drug. Active tuberculosis, particularly if it's a drug-resistant strain, will require several drugs at once. The most common medications used to treat tuberculosis include:

  • Isoniazid
  • Rifampin (Rifadin, Rimactane)
  • Ethambutol (Myambutol)
  • Pyrazinamide

If you have drug-resistant TB, a combination of antibiotics called fluoroquinolones and injectable medications, such as amikacin or capreomycin (Capastat), are generally used for 20 to 30 months. Some types of TB are developing resistance to these medications as well.

Some drugs may be used as add-on therapy to the current drug-resistant combination treatment, including:

  • Bedaquiline (Sirturo)
  • Linezolid (Zyvox)
The TB treatment usually lasts for 6-9 months. This is for an entire recovery and prevent any relapse. If the treatment isn't thorough, when TB comes back again it can be drug-resistant.

Why is Extensively drug-resistant -XDR TB so serious?

Because XDR TB is resistant to the most powerful first-line and second-line drugs, patients are left with treatment options that are much less effective and often have worse treatment outcomes. XDR TB is of special concern for persons with HIV infection or other conditions that can weaken the immune system. These persons are more likely to develop TB disease once they are infected, and also have a higher risk of death once they develop TB disease.
