Fish oil and statins can be used together. Fish oil is a nutraceutical that may have some benefit in controlling blood lipids, but does not have medicinal value. Patients with elevated blood lipids need regular oral statin therapy on top of diet control to effectively control blood lipid levels. For patients with hyperlipidemia, fish oil can be taken appropriately, and fish oil can also be used in combination with statins at the same time, but the main focus is on the therapeutic effects of statins, and fish oil cannot be relied upon to lower blood lipids. The main role of statin drugs is to limit the synthesis of cholesterol, clinically mainly used in the treatment of hypercholesterolemia, the adverse effects of the drug are nausea, vomiting, abdominal pain, muscle aches and pains, etc. Allergy to drug components, unexplained elevation of liver enzymes, patients with severe hepatic impairment is prohibited. Patients with hyperlipidemia should be treated in a formal manner under the guidance of a physician.
