abnormal liver function tests can be common when on statins, a review of this should allow your practitioner to alter the dose and or type of drug.
Bewary of consuming grapefruit juice with some types of statins.
Some people and perhaps unwisely, take grapefruit juice to increase the effect of the cheaper statins. A enzyme reaction in intestinal cells is inhibited by grapefruit juice making them more long-lived and having a greater effectiveness with increased potential for toxicity.
An excerpt from wikipedia (yes I know it's not the most robust of evidence resources....blah!)
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 lovastatin, simvastatin and to a lesser degree atorvastatin) and some other medications
[21] (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.
It is interesting that NorwaySchlong noted erection quality improvements though...
