Vascepa is a prescription medication that contains only the active ingredient icosapent ethyl, which is a type of omega-3 fatty acid. This medication is used to lower high levels of triglycerides, which are a type of fat found in the blood. Vascepa differs from other medications in its class, such as Lovaza, because it contains only the purified form of icosapent ethyl and does not contain any other omega-3 fatty acids [1][2][3].

Lovaza, on the other hand, contains a combination of omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Lovaza is also used to lower high levels of triglycerides in the blood, but it may also increase levels of low-density lipoprotein (LDL) cholesterol, which is considered the "bad" cholesterol [2][3].

Vascepa has been shown to be effective in reducing triglyceride levels in patients with high triglycerides, with fewer side effects than Lovaza. Additionally, Vascepa has been approved by the FDA to reduce the risk of cardiovascular events, such as heart attack and stroke, in patients with high triglycerides and other cardiovascular risk factors [1][3].

In summary, Vascepa differs from other medications in its class, such as Lovaza, because it contains only the purified form of icosapent ethyl and does not contain any other omega-3 fatty acids. Vascepa has been shown to be effective in reducing triglyceride levels with fewer side effects than Lovaza, and it has also been approved by the FDA to reduce the risk of cardiovascular events in patients with high triglycerides and other cardiovascular risk factors [1][2][3].
