Rifampin has been shown to produce hepatotoxicity in patients with preexisting liver dysfunction and in patients with normal liver function who are also taking other hepatotoxic agents. Some cases have been fatal. Patients with impaired liver function should only be given isoniazid-rifampin in cases of necessity and then with caution and under strict medical supervision. Careful monitoring of liver function especially SGPT and SGOT should be done prior to and then every 2 to 4 weeks throughout treatment in patients with liver dysfunction.

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.

During this process, rifampin undergoes progressive deacetylation so that nearly all the drug in the bile is in this form in about 6 hours. This metabolite has antibacterial activity. Intestinal reabsorption is reduced by deacetylation, and elimination is facilitated. Up to 30% of a dose is excreted in the urine, with about half of this being unchanged drug. alendronate price at cvs pharmacy

Large trials of statins have shown no difference in the frequency or degree of ALT increases between treatment and placebo groups. Out-of-range values, which do occur with statin use, eventually return to normal even if the same statin is continued. The occurrence of acute liver failure thought to be caused by statins is well below what is now understood as the background rate of idiopathic acute liver failure in the general population. No consistent liver- biopsy picture from possible statin-related drug injury has emerged, and there are no reports of chronic carriers of drug-induced liver damage from statins. Thus, an increased ALT in this situation is not a disease. Davis CE Jr, Carpenter JL, Ognibene AJ, McAllister CK "Rifampicin-induced acute renal failure. GlaxoSmithKline. Avandia rosiglitazone maleate tablets prescribing information. Research Triangle Park, NC; 2007 Jun. DALIRESP if such events occur.
