Fenofibrate belongs to the class of medications known as fibrates. It is used in addition to diet and exercise to treat people with abnormal cholesterol levels.

Fenofibrate (micronized) reduces bad cholesterol (low-density lipoproteins [LDL] and very low-density lipoproteins [VLDL]) and triglycerides in your blood. It also increases good cholesterol (high-density lipoprotein [HDL]) levels. Bringing cholesterol levels in the blood into the desired range has been shown to reduce the risks associated with heart disease, such as heart attack.
