Patient Education

Gemfibrozil


Gemfibrozil is used with diet changes (restriction of cholesterol and fat intake) to reduce the amount of cholesterol and triglycerides (other fatty substances) in the blood in certain people with very high triglycerides who are at risk of pancreatic disease (conditions affecting the pancreas, a gland that produces fluid to break down food and hormones to control blood sugar). Gemfibrozil is also used in people with a combination of low high-density lipoprotein (HDL; 'good cholesterol') levels and high low-density lipoprotein (LDL; 'bad cholesterol') and triglyceride levels to reduce the risk of heart disease. Gemfibrozil is in a class of lipid-regulating medications called fibrates. It works by reducing the production of triglycerides in the liver.
