Q-Tor Special Precautions

Atorvastatin should be used with caution in patients who consumes substantial quantities of alcohol and/or have a history of liver disease. Active liver disease or unexplained persistent transaminase elevations are contraindications to the use of Atorvastatin.
Skeletal Muscle: Rhabdomyolysis with or without renal impairment has been reported with the use of HMG-CoA reductase inhibitors.
Myalgia has been reported in patients treated with Atorvastatin. Myopathy, defined as muscle aching or muscle weakness in conjunction with increases in creatinine phosphokinase (CPK) values greater than 10 times the upper limit of normal, should be considered in any patient with diffuse myalgias, muscle tenderness or weakness, and/or marked elevation of CPK. As with other HMG-CoA reductase inhibitors, the risk of myopathy during treatment with Atorvastatin is increased with concurrent administration of immunosuppressive drugs, including cyclosporine, fibric acid derivatives, nicotinic acid, azole antifungals or erythromycin.
Effects on ability to drive and use machines: Atorvastatin has negligible influence on the ability to drive and use machines.
