Pyrazinamide is an antibiotic medication primarily used to treat tuberculosis (TB). It works by inhibiting the growth of the bacteria that cause TB, making it an essential part of combination therapy for this infectious disease. Pyrazinamide is usually administered alongside other TB medications to enhance effectiveness and prevent resistance. This drug is typically taken orally and is well-absorbed in the body. Common side effects may include liver toxicity, joint pain, and gastrointestinal issues. Regular monitoring of liver function is recommended during treatment to ensure safety and effectiveness.
