How does this medication work? What will it do for me?

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

Fenofibrate 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 [LDL]) levels. Reduction of cholesterol levels in the blood has been shown to reduce the risks associated with heart disease, such as heart attack.
