When taking anti-tuberculosis drugs, symptoms of gastrointestinal irritation, such as anorexia and abdominal distention, usually occur and are not severe enough to require special treatment. Most anti-tuberculosis drugs may also cause damage to the liver, as well as often allergies, decreased white blood cells, and peripheral neuritis. If liver function damage is not severe, liver-protective therapy can be given. If severe liver damage occurs, antituberculosis drug therapy needs to be stopped. When severe liver damage occurs, discomfort such as nausea, vomiting and abdominal distension can occur. Commonly used anti-tuberculosis drugs include isoniazid, rifampin, pyrazinamide, ethambutol, etc. Among them, pyrazinamide can reduce uric acid excretion in the blood, which can increase uric acid and induce gout attacks.
