Hello, I can understand your concern regarding the Atorvastatin. Itching may be due allergic reaction to Atorvastatin. The most common side effects of cholesterol lowering medication Atorvastatin includes muscle aches, fatigue, tenderness or weakness, stomach upset, and liver dysfunction. Although less common however, flushing of the skin and itching can also occur in some patients. I advise you to consult your treating doctor to prescribe an alternate effective but a safer cholesterol lowering medication. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Mohammed Taher Ali
