Gemfibrozil is a medication used to help lower high triglyceride levels in the blood, particularly in adults who are at risk for pancreatitis and haven't had enough success with diet alone. It works by reducing the amount of fat produced by the liver and increasing the levels of good cholesterol in the body. You take it in tablet form, with the usual starting dose being 1,200 mg per day, divided into two doses taken 30 minutes before meals, and this can go up to a maximum of 1,200 mg. A key warning is that it should not be used if you have severe liver or kidney problems, or gallbladder disease. Additionally, you should avoid taking gemfibrozil with simvastatin, as this combination can significantly increase the risk of serious muscle problems.
