Lovaza vs. Vascepa - what's the difference between them?
- Both Lovaza and Vascepa are prescription oral medications used in addition to diet to help lower high triglyceride levels that can be dangerous for your heart.
- However, Vascepa is also approved to be used with a statin in certain high risk groups with high triglycerides to lower the risk of outcomes like a heart attack or stroke.
- Lovaza is not approved to be used with a statin for this purpose and it is not known if Lovaza prevents you from having a heart attack or stroke.
