RESUMO
A large percentage of the US population is either receiving or should be considered for statin therapy. Whether through primary or secondary prevention for atherosclerotic disease, statins remain one of the mainstay options available to physicians. Myalgias are the most commonly reported side effects, though largely self-limited and subjective in nature. Here, we report a case of drug-related myonecrosis following long-term use of atorvastatin. Prompt recognition of the condition and initiation of treatment is paramount to control the disease's progression. While high-dose steroids are first line, quick escalation to methotrexate, IVIG or rituximab should be considered in refractory cases. This decision is guided by monitoring of serum markers such as CK and transaminases. The goal is quick normalisation of these enzymes, signalling cessation of underlying muscle necrosis. Patients may never regain full function and treatment can last months to years.
