Why is Gemfibrozil prescribed?

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. Gemfibrozil is in a class of lipid-regulating medications called fibrates. It works by reducing the production of triglycerides in the liver.

Buildup of cholesterol and fats along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to your heart, brain, and other parts of your body. Lowering your blood level of cholesterol and fats may help to decrease your chances of getting heart disease, angina (chest pain), strokes, and heart attacks. In addition to taking a cholesterol-lowering medication, making certain changes in your daily habits can also lower your cholesterol blood levels. You should eat a diet that is low in saturated fat and cholesterol (see SPECIAL DIETARY), exercise 30 minutes on most, if not all days, and lose weight if you are overweight.

How should Gemfibrozil be used?

Gemfibrozil may come as a tablet to take by mouth. It is usually taken twice a day, 30 minutes before the morning and evening meals. Take gemfibrozil at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor to explain any part you do not understand. Take gemfibrozil exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Gemfibrozil controls high cholesterol and triglycerides but does not cure them. Continue to take gemfibrozil even if you feel well. Do not stop taking gemfibrozil without talking to your doctor.

Other uses for Gemfibrozil

Gemfibrozil may be prescribed for other uses; ask your doctor for more information.
