Pyrazinamide is a drug that is given during the intensive treatment phase in combination with other medications. During the intensive treatment phase a large number of drugs is given simultaneously in order to control the tuberculosis infection as quickly and as effectively as possible. You will receive a dose that is adjusted to your body weight. Pyrazinamide is not usually given throughout the whole duration of therapy, but this be required in cases of drug resistant tuberculosis. Please ask your physician how long you will receive Pyrazinamide for. This drug can affect your liver and regular blood tests are required to monitor your liver function. To protect your liver, you should abstain from alcohol during the treatment period. Other side effects include nausea and vomiting, aching joints and muscles, or facial blushing. Occasionally, your blood results may change – such as the level of uric acid in your blood- but usually this does not have an adverse effect on your health. Please inform your doctor about any side effects that you observe. Your doctor may be able to adjust your treatment regimen accordingly.
