methimazole liver side effects
- Methimazole can cause liver damage that is typically characterized by cholestasis, but no cases of liver damage resulting in transplantation or death have been described [17 r]. A 60-year-old man with hyperthyroidism developed cholestasis and acute cholecystitis after taking methimazole for 4 days; the cholestasis improved rapidly after withdrawal of antithyroid drug therapy [19 A].
