Why Does Simvastatin Cause Muscle Pain?

While in most cases simvastatin-induced muscle pain itself is nothing but a discomfort,  it may be a symptom of muscle tissue damage and developing such diseases as myopathy and rhabdomyolysis, both of which may cause severe muscle pain and are a real treat to a patient’s life. Rhabdomyolysis is a degenerative muscle tissue condition that may cause liver problems, kidney damage or heart failure leading to death.  The risk of Rhabdomyolysis significantly increases when simvastatin is taken together with other drugs or after overdosing.  Recent studies show that muscle damage occurs because simvastatin activates the gene atrogin-1 gene playing a key role in muscle atrophy and impairment of muscle fiber. In fact, muscle problems are a #1 cause of simvastatin lawsuits.

Although such severe conditions occur in less than 0.1 percent of patients taking simvastatin, you can never be too cautious about any muscle symptoms while on simvastatin.
