Vascepa is a prescription medication used to treat high levels of triglycerides in the blood. It contains a type of omega-3 fatty acid called eicosapentaenoic acid (EPA) and is approved by the FDA for use in adults with triglyceride levels above 150 mg/dL.

Regarding the duration of Vascepa assistance, it is not entirely clear what is meant by "assistance." If the question is referring to how long the drug remains effective in reducing triglyceride levels, then according to Drugs.com [3], it can take up to 12 weeks of treatment for Vascepa to show significant reductions in triglyceride levels. After that, the medication should continue to be effective as long as it is taken as prescribed.

However, the drug's official website [2] does offer a savings card that can be used to reduce the cost of Vascepa prescriptions for eligible patients.
