Severe and sometimes fatal hepatitis associated with isoniazid therapy may occur or develop after months of treatment. The risk is age related with a greater occurrence reported in patients who are 35 years or older. The risk of hepatitis is also increased in patients who consume alcohol daily, in women, and in minorities. Monthly monitoring and interviewing of patients should take place. Baseline laboratory values should be obtained in patients over 35 years of age and in patients with a history of liver illness or heavy alcohol consumption. Elevated liver function tests per se are not a contraindication to the use of isoniazid unless they indicate worsening or acute liver disease. Strict monitoring of these patients, however, is crucial. Patients should be fully informed regarding the risk of hepatotoxicity associated with isoniazid, educated about the prodromal symptoms of hepatitis such as anorexia, nausea, vomiting, fatigue, weakness, or malaise and instructed to contact their physician immediately if they develop signs or symptoms. Isoniazid should be discontinued at once if these symptoms occur or signs indicative of liver damage are detected; continued use of isoniazid in such cases has been reported to cause a more severe form of liver damage.

Rifampicin is an approved anti-mycobacterial drug that is a standard component of combination regimens for treating tuberculosis. Rifampicin is a generic non-brandname product; it is known as rifampin in the USA. It is manufactured by Merrell under the tradename Rifadin, and by Ciba Geigy under the tradename Rimactane. A number of tablets that contain rifampicin in combination with other anti-tuberculosis drugs are also on the market. TB treatment regimens that contain rifampicin are generally more effective than non-rifampicin-containing regimens. However, drug interactions between rifampicin and many anti-HIV drugs mean that rifampicin is not always used for HIV-infected people with TB. Guidelines published in early 2000 recommend the use of rifabutin instead of rifampicin for the treatment of TB in people taking antiretroviral therapy. Product Information. Rifadin rifampin.

Rifampin may infrequently cause hematopoietic abnormalities such as thrombocytopenia, leukopenia, decreased hemoglobin, and acute hemolytic anemia. Hemolysis has been described as part of an immune-mediated reaction which generally occurs after gaps in therapy. Thrombocytopenia is observed most frequently in patients receiving high-dose intermittent therapy or after a lapse in therapy, but very rarely during daily administration. It is reversible if rifampin is discontinued as soon as purpura appears. Patients with preexisting bone marrow depression or blood dyscrasias should be monitored closely during rifampin therapy for further decreases in blood counts.
