Prescription-strength fish oil recommended for those at risk of strokes and heart attacks

The Food and Drug Administration is recommending broader use of the prescription-strength fish oil Vascepa for those at risk of heart attacks and strokes. Right now the drug is being used for a narrow group of people with high levels of triglycerides, but the drug maker Amarin is looking to expand use of the fish oil for patients with lower fat levels who still are at risk of heart problems. We talk to cardiologist Dr. Brian Hardaway of the Mayo Clinic about the drug.
