Let your doctor know immediately. pyrazinamide can cause liver problems; make sure you are having your liver function checked.

    Pyrazinamide may produce a temporary decrease in ketosteroids and an increase in protein-bound iodine. Interactions Drug: Increase in liver toxicity (including fatal hepatoxicity in when treating latent TB) with rifampin. Pharmacokinetics Absorption: Readily absorbed from GI tract. Peak: 2 h. Distribution: Crosses blood–brain barrier.   Rationale: Relatively little is known about the hepatotoxicity of pyrazinamide.. Objectives: We compared continuation-phase regimens incorporating pyrazinamide, isoniazid, and/or rifampin with those containing isoniazid and rifampin to evaluate the hepatotoxicity of pyrazinamide.. Methods: Cohort and nested case-control analyses were conducted on a cohort of 3, patients with active Cited by:

Salmonella mutagenicity tests: III. Results from the testing of chemicals. Environ Mutagen. ; 9 (Suppl 9): : Maximal Daily Dose in Children and Adults. A bioassay of the tuberculostatic drug pyrazinamide for possible carcinogenicity was conducted by administering the test chemical in feed to Fischer rats and B6C3F1 mice.

Groups of 35 rats and 35 mice of each sex were administered pyrazinamide at one of two doses, either 5, or 10, ppm, for 78 weeks, and then observed for an additional. Pyrazinamide tablets form the bulkiest part of the standard tuberculosis treatment regimen.
