Do I have to take TB medicine?

  • Active TB
    Medicines must be taken to get better and to stop the spread of TB to others.
  • Inactive TB
    Taking medicine is not mandatory, but it is usually a good idea because it can lower the risk of you getting sick with active TB in the future. Certain long term medical conditions make the chances of you getting sick with active TB much higher. This makes taking medicine to prevent active TB even more important.
