Acute hepatitis due to fluoxetine therapy

Abstract

Fluoxetine-induced hepatotoxicity is generally considered of minimal clinical importance and is not well recognized. Asymptomatic increases in liver enzyme values have been observed in 0.5% of patients who take long-term fluoxetine therapy. This report details 2 cases of acute hepatitis believed to be caused by fluoxetine. Three cases of acute hepatitis caused by fluoxetine have been reported previously. The mechanism of fluoxetine-induced hepatotoxicity is unknown. Although routine monitoring of liver function may not be cost-effective, physicians should be alert to the possibility of fluoxetine-associated hepatitis and consider early discontinuation of the drug if this condition is suspected.
