PRESCRIBED FOR: Vytorin is used for reducing total cholesterol, LDL cholesterol and triglycerides, and increasing HDL cholesterol.
SIDE EFFECTS: The most common side effects of Vytorin are:
Hypersensitivity reactions also have been reported. The most serious potential side effects are liver damage and muscle inflammation or breakdown. The simvastatin component of Vytorin is a statin. Therefore it shares side effects, such as liver and muscle damage associated with statins. Serious liver damage caused by statins is rare. More often, statins cause abnormalities of liver tests, and, therefore, periodic measurement of liver tests in the blood is recommended for all statins. Abnormal tests usually return to normal even if a statin is continued, but if the abnormal test value is greater than three times the upper limit of normal, the statin usually is stopped. Liver tests should be measured before Vytorin is started and periodically thereafter or if there is a medical concern about liver damage.
Inflammation of the muscles caused by statins can lead to a serious breakdown of muscle cells called rhabdomyolysis. Rhabdomyolysis causes the release of muscle protein (myoglobin) into the blood. Myoglobin can cause kidney failure and even death. When used alone, statins cause rhabdomyolysis in less than one percent of patients. To prevent the development of rhabdomyolysis, patients taking Vytorin should contact their health care professional immediately if they develop unexplained muscle pain, weakness, or muscle tenderness.
Statins have been associated with increases in HbA1c and fasting serum glucose levels that are seen in diabetes. There are also post-marketing reports of memory loss, forgetfulness, amnesia, confusion, and memory impairment. Symptoms may start 1 day to years after starting treatment and resolve within a median of 3 weeks after stopping the statin.
