Acute reactive hepatitis in pregnancy induced by alpha-methyldopa.

Abstract

Alpha-methyldopa is an antihypertensive medication used commonly in pregnancy. Reactive hepatitis is a severe, uncommon reported side effect of this medication. To our knowledge, there has been only one other reported case of alpha-methyldopa-induced hepatitis associated with pregnancy in the United States. A patient at 17 weeks' estimated gestational age was evaluated for elevated maternal serum alpha-fetoprotein, which is used generally as a screening test for birth defects. A thorough history, physical examination, and laboratory evaluation were performed, and alpha-methyldopa-induced maternal hepatitis was diagnosed. The astute clinician should include maternal hepatic dysfunction in the differential diagnosis of an elevated maternal serum alpha-fetoprotein and should consider obtaining aminotransferase levels after initiation of alpha-methyldopa therapy during pregnancy.
