"Cholestatic hepatitis, hepatic cirrhosis, rhabdomyolysis and myositis have been reported in patients receiving the drug chronically"
I got the above quote from my wikipedia search on Simvastatin: http://en.wikipedia.org/wiki/Simvastatin
that's all ******** to stop the use of simvastatin because it is too cheap and generic now.sim has shown to cure end stage cirrhosis with portal hypertension and to prevent liver cancer...quite the opposite.
they just used very rare cases of people that never checked alt and got these severe diseases, actually it is not even proven it was sim to do that, but in any case if you fall among the extremely rare cases where there is an alt rise you have to rethink use of sim.the rise of alt is not even proven to be liver damage....see liver specialists and researchers report (the other claims were by ignorants on liver)

June 11, 2007 ? A new review of the safety of statins has concluded that
these drugs are well tolerated, with their main adverse effects ? myopathy
and rhabdomyolysis ? occurring very rarely at standard doses.
"With a few caveats and while awaiting good quality randomized data for the
newer drugs, statins seem to be a remarkably safe group of drugs when used
at their usual doses," the author, Dr Jane Armitage (University of Oxford,
UK), concludes.
The review, published online in The Lancet on June 7, includes all papers
published between 1985 and 2006 on the safety, efficacy, and side effects of
statins. Armitage notes that since statins were first approved in 1987,
their ability to reduce the risks of vascular death, non-fatal MI, stroke,
and the need for arterial revascularization has been shown by several large,
high-quality randomized trials. But she adds that hopes that statins might
protect against fractures, dementia and macular degeneration have not been
supported by evidence from randomized trials.
Myopathy
Armitage says the only well-documented, consistent adverse effects
associated with statins are muscle toxicity, including myopathy and
rhabdomyolysis, and effects on liver enzymes. She states that all statins
occasionally cause myopathy which could progress to rhabdomyolysis but she
estimates that myopathy occurs in fewer than one in 10,000 patients at
standard doses of statins; and while the risk increases with higher statin
doses, it remains very low with atorvastatin 80 mg. Myopathy or
rhabdomyolysis are usually reported in association with concomitant use of
interacting drugs (especially fibrates), the review notes, adding that this
side-effect is most likely to occur within a few months of starting statin
treatment, or of increasing the dose, although some cases have been reported
even after some years of apparently stable statin treatment, usually as the
result of starting an interacting drug.
Armitage points out that muscle pain is common in middle-aged patients (and
often believed to be due to the drug because of product warnings), but is,
nevertheless, unlikely to be due to statin treatment. Measurement of
creatine kinase in such patients can exclude myopathy and allow safe
continuation of treatment, she says. Importantly, any risks of myopathy and
rhabdomyolysis can be kept to a minimum by knowledge of potential drug
interactions and the vulnerability of particular groups of patients, she
adds.
Transaminase Increases
The review reports that a small percentage of patients taking statins
experience an increase in liver enzymes (in particular, alanine and
aspartate transaminases), generally seen in the first 6 months of treatment.
These are asymptomatic, are reversible on stopping the statin treatment or
with dose reduction, and there is no convincing evidence from the statin
trials that increases in either transaminase are associated with liver
damage, Armitage writes. She adds that the effect on transaminases seems to
be dose dependent, and effects on other liver enzymes and bilirubin also
emerge with higher doses, but unlike with myopathy, the effects might be
because of a greater fall in LDL cholesterol. But even at high doses, these
liver enzyme increases have not been associated with hepatitis or liver
failure.
She notes that routine monitoring of liver function after starting statin
treatment is no longer recommended for simvastatin, pravastatin, or
lovastatin up to 40 mg daily, but remains recommended for the other statins
and higher doses. If transaminases are more than three times the upper limit
of normal in an asymptomatic patient with no other liver abnormalities, the
enzymes should be checked within a week and statin treatment stopped
temporarily if alanine transaminase is still at this level. Increases to
between two to three times the upper limit of normal in an asymptomatic
patient necessitate monitoring, but will often resolve while on treatment.
The review also examines the safety of statins in several vulnerable groups.
It says that no adjustment of dosage is needed for the elderly, since people
aged up to 80 years were recruited in the various trials, but that the very
elderly may be at increased risk of myopathy. It also reports that there is
no evidence to suggest people consuming excess alcohol are at greater risk
of side effects from statin use, although many such people were excluded
from statin trials. Warfarin users may need to adjust the amount of the
anticoagulant when statin treatment begins and again when it ends, it adds.
