Gemfibrozil (gemfibrozil) — Uses, Dosage, Side Effects & Safety

Drug class: Fibrate (Antilipemic agent)

Overview

Gemfibrozil is a medication used to help lower high levels of cholesterol and triglycerides in the blood, especially in people at risk for pancreatitis or those who have not responded adequately to diet and lifestyle changes alone. It is most commonly prescribed for adults with hypertriglyceridemia or mixed dyslipidemia. Gemfibrozil works by decreasing the amount of fat produced by the liver and increasing the removal of triglycerides from the blood. It belongs to the class of drugs called fibrates, which help improve cholesterol balance by lowering triglycerides and, to a lesser extent, raising HDL ("good") cholesterol. Key points for patients: Take gemfibrozil exactly as prescribed, usually twice daily before meals. Regular blood tests are needed to monitor your cholesterol and liver function. Always inform your healthcare provider about all medications you are taking, as gemfibrozil can interact with other drugs.
