Take the Liver Disease Quiz

Acute liver failure

Rarely, drugs cause acute liver failure (fulminant hepatitis). These patients are extremely ill with the symptoms of acute hepatitis and the additional problems of confusion or coma (encephalopathy) and bruising or bleeding (coagulopathy). In fact, 70% to 90% of people with fulminant hepatitis die. In the U. S., acetaminophen (Tylenol) is the most common cause of acute liver failure.

Cholestasis

Cholestasis is a condition in which the secretion and/or flow of bile is reduced. Bilirubin and bile acids normally secreted by the liver into bile and eliminated from the body via the intestine, collect in the body leading to jaundice and itching, respectively. Drugs causing cholestasis typically interfere with the liver cell's secretion of bile without causing hepatitis or liver cell necrosis (death). Patients with drug-induced cholestasis typically have elevated blood levels of bilirubin but have normal or mildly elevated AST and ALT levels. Blood levels of alkaline phosphate (an enzyme made by bile ducts) increase because the cells of the bile ducts also are dysfunctional and leak the enzyme. Aside from itching and jaundice, patients usually are not as sick as patients with acute hepatitis.

Examples of drugs that have been reported to cause cholestasis include erythromycin (E-Mycin, Ilosone), chlorpromazine (Thorazine), sulfamethoxazole and trimethoprim (Bactrim; Septra), amitriptyline (Elavil, Endep), carbamazepine (Tegretol), ampicillin (Omnipen; Polycillin; Principen), ampicillin/clavulanic acid (Augmentin), rifampin (Rifadin), estradiol (Estrace; Climara; Estraderm; Menostar), captopril (Capoten), birth control pills (oral contraceptives), anabolic steroids, naproxen (Naprosyn), amiodarone (Cordarone), haloperidol (Haldol), imipramine (Tofranil), tetracycline (Achromycin), and phenytoin (Dilantin).

Most patients with drug-induced cholestasis will recover fully within weeks after stopping the drug, but in some patients, jaundice, itching, and abnormal liver tests can last months after stopping the drug. An occasional patient can develop chronic liver disease and liver failure. Drug-induced jaundice and cholestasis lasting longer than 3 months is called chronic cholestasis.
