How It Works

These drugs lower triglycerides and raise HDL ("good") cholesterol. They may have little effect on LDL ("bad") cholesterol levels.

Gemfibrozil may be used to reduce the risk of heart attack in people with coronary artery disease (CAD) who have low HDL and high triglycerides.

How Well It Works

Gemfibrozil may lower the risk of heart attack in people who have CAD and low HDL levels.2

  • Usually the benefits of the medicine are more important than any minor side effects.
  • Side effects may go away after you take the medicine for a while.

Taking medicine

There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
