Treatment of TB
TB can be LIFE-THREATENING if you do not get the correct treatment. It can spread to other parts of the body such as the spine, kidney or brain. LATENT TB can also progress to active TB especially in people who have weakened immune system such as cancer, HIV, diabetes, malnutrition or smokers. Treatment of TB requires several (between 3-9) months to ensure complete cure. You may be required to take a combination of the following medications. It is IMPORTANT that you take ALL the medicine you are prescribed and NOT miss or stop taking any of them. This is to prevent the bacteria from becoming resistant to drugs or you getting TB recurrences in the future. The medication consists of the combination of these 4 drugs;
- Isoniazid
- Pyrazinamide
- Ethambutol
- Rifampicin
