Lipitor is a brand name for the drug atorvastatin, which is a statin medication used to lower cholesterol levels in the body. Fish oil is a dietary supplement that contains omega-3 fatty acids, which are known to have heart-healthy benefits.

There is no known interaction between taking Lipitor and fish oil together, and it is generally considered safe to do so. In fact, some studies have shown that taking fish oil supplements in addition to statin medications like Lipitor may provide additional cardiovascular benefits [2].

However, it is important to note that taking a statin medication like Lipitor may reduce the levels of certain fatty acids in the body, including omega-3 fatty acids [3]. This does not mean that taking fish oil supplements is ineffective or harmful, but it may mean that higher doses of fish oil are needed to achieve the desired health benefits.

Overall, it is safe to take Lipitor and fish oil together, but it is important to talk to a healthcare provider before starting any new medications or supplements. They can provide personalized recommendations based on an individual's health history and current medications.
