Grapefruit and any fibrates: some Fibrates are: Bezafibrate (e.g. Bezalip) Ciprofibrate (e.g. Modalim) Clofibrate Gemfibrozil (e.g. Lopid) Fenofibrate (e.g. TriCor) This is what Wikipedia has to say: Drug interactions Combining any statin with a fibrate, another category of lipid-lowering drugs, increases the risks for rhabdomyolysis to almost 6.0 per 10,000 person-years.[13] Most physicians have now abandoned routine monitoring of liver enzymes and creatine kinase, although they still consider this prudent in those on high-dose statins or in those on statin/fibrate combinations, and mandatory in the case of muscle cramps or of deterioration in renal function. Consumption of grapefruit or grapefruit juice inhibits the metabolism of statins—furanocoumarins in grapefruit juice inhibit the cytochrome P450 enzyme CYP3A4, which is involved in the metabolism of most statins (however it is a major inhibitor of only atorvastatin, lovastatin and simvastatin) and some other medications[16] (it had been thought that flavonoids were responsible). This increases the levels of the statin, increasing the risk of dose-related adverse effects (including myopathy/rhabdomyolysis). Consequently, consumption of grapefruit juice is not recommended in patients undergoing therapy with most statins. An alternative, somewhat risky, approach is that some users take grapefruit juice to enhance the effect of lower (hence cheaper) doses of statins. This is not recommended as a result of the increased risk and potential for statin toxicity.
