This 48-year-old man with possible underlying myopathy was successfully treated with ezetimibe 10 mg/day and rosuvastatin 5 mg every other day for 17 months. Three weeks before presentation, he began drinking pomegranate juice (200 ml twice weekly). He presented urgently with thigh pain and an elevated serum creatine kinase level (138,030 U/L, normal < 200 U/L). In conclusion, because both grapefruit and pomegranate juice are known to inhibit intestinal cytochrome P450 3A4, this report suggests that pomegranate juice may increase the risk of rhabdomyolysis during rosuvastatin treatment, despite the fact that rosuvastatin is not known to be metabolized by hepatic P450 3A4.
