Gemfibrozil Interactions with Dietary Supplements
Coenzyme
Q10
In a randomized study of 21 men with combined hyperlipidemia, ten to twelve weeks of
gemfibrozil therapy reduced coenzyme Q10 blood levels to the levels seen in healthy
men.1 The clinical significance of this finding is unknown.
Vitamin
E
In a randomized study of 21 men with combined hyperlipidemia, ten to twelve weeks of
gemfibrozil therapy reduced alpha- and gamma-tocopherol blood levels to the levels seen in
healthy men.2 The clinical significance of this finding is unknown and may reflect
a normal physiological response to a reduction in serum cholesterol levels.
Vitamin B3
(Niacin)
Niacin (not niacinamide) and gemfibrozil have successfully raised HDL (good) cholesterol
levels, both alone and in combination.3
Gemfibrozil Interactions with Herbs
Red yeast
rice (Monascus purpureus)
Monascus purpureus, a form of red yeast, is fermented with rice to produce a dietary
supplement, Cholestin®, that contains low levels of lovastatin, a drug otherwise available only by
prescription. taken with the prescription drug lovastatin has been reported to
cause rhabdomyolysis, a potentially life-threatening muscle disease.4 People taking
gemfibrozil should avoid lovastatin-containing products, including Cholestin®, until more
is known. The levels of lovastatin in Cholestin® are significantly lower than those given
of the drug as a single agent. Cholestin® also contains numerous other compounds that may
alter the interaction of lovastatin and gemfibrozil.
Gemfibrozil Interactions with Foods and Other Compounds
Food
should be taken 30 minutes before meals.5

may cause dizziness or blurred vision.6 Alcohol may intensify these
effects, increasing the risk for accidental injury. People taking gemfibrozil should avoid
