TB can usually be cured and more than twenty drugs have been developed for treating TB. But most of the drugs were developed many years ago. The #treatment usually consists of a combination of TB drugs that must be taken for at least six months. But the treatment will only be successful if the drugs are taken exactly as required for the entire length of time.

The drugs are used in different combinations in different #circumstances. For example, the five “first line” drugs are given to people who have never had #treatment before. If people have had treatment before they may need to take second line #drugs.

Some of the drugs have very severe side effects and are very difficult to take for such a long #period of time. This is why there is an urgent need for new TB drugs to be developed. In addition many #people are now resistant to one or more of the drugs.
