With treatment, TB can usually be cured. Most people will need a course of antibiotics, usually for six months. Several different antibiotics are used. This is because some forms of TB are resistant to certain antibiotics. If you are infected with a drug-resistant form of TB, treatment with six or more different medications may be needed. If you are in close contact with someone who has TB, tests may be carried out to see if you are also infected. These can include a chest X-ray, blood tests, and a skin test called the Mantoux test.
