Does Lipitor cause muscle pain?
Direct Answer
Muscle symptoms (myalgia) are the most commonly reported side effect of Lipitor (atorvastatin), affecting roughly 5-10% of patients in clinical practice. Statins reduce CoQ10 production as a byproduct of blocking cholesterol synthesis, which may contribute to muscle complaints. The SLCO1B1 gene variant significantly increases myopathy risk at high doses. However, "nocebo effect" studies suggest some muscle pain attributed to statins is not actually caused by them — blinded trials show much lower rates than open-label use. Serious muscle breakdown (rhabdomyolysis) is very rare, estimated at 1-3 per 100,000 patient-years.
