A study published in the Journal of Clinical Pharmacology found that fish oil, particularly its high levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), can affect the metabolism of various drugs, including statins like Lipitor [1].
Research conducted by the University of Washington, School of Pharmacy, revealed that EPA and DHA can inhibit the activity of CYP3A4, an enzyme responsible for metabolizing Lipitor [2]. This inhibition can increase the levels of Lipitor in the bloodstream, potentially leading to increased risk of side effects, such as muscle damage and liver toxicity.
According to the FDA-approved label for Lipitor, grapefruit and grapefruit juice can also inhibit CYP3A4, leading to increased levels of the drug in the body [3]. Similar to grapefruit, fish oil may also interact with Lipitor through this mechanism.
However, more research is needed to fully understand the extent of this interaction and its clinical implications. It is essential for individuals taking Lipitor to consult their healthcare providers before adding fish oil supplements to their regimen.
