Fenofibrate is used to lower elevated
cholesterol and triglyceride levels when
diet, exercise, and weight loss programs are ineffective. It is in a family of medications
known as cholesterol-lowering drugs.

Interactions with Dietary Supplements
Vitamin C and Vitamin E
Several studies have shown that fenofibrate enhances the toxic effect of ultraviolet (UV)
radiation from the sun, which might result in side effects such as skin rashes. One controlled
study showed that taking 2 grams of vitamin C and 1,000 IU of vitamin E prior to ultraviolet
exposure dramatically blocked UV-fenofibrate damage to red blood cells.1 though
further controlled studies are needed, people taking fenofibrate should probably supplement
with vitamins C and E until more information is available.
Folic acid, Vitamin B6, and Vitamin
B12
Increased blood levels of homocysteine are
associated with increased risk of atherosclerosis
and heart disease. One study revealed that
fenofibrate dramatically increases blood homocysteine levels, though blood levels of vitamins
were not reduced.2 Further research is needed to determine whether supplemental
folic acid, vitamin B6, and vitamin B12 might lower fenofibrate-induced elevations in
homocysteine blood levels.
Interactions with Foods and Other Compounds
Food
Taking fenofibrate together with food dramatically increases the absorption of the
drug.3 Therefore fenofibrate should be taken with a meal.
