Vascepa is a prescription medication used to reduce triglyceride levels in adults. The active ingredient in Vascepa is icosapent ethyl, which is a type of omega-3 fatty acid. As of September 2021, there are no generic versions of Vascepa available on the market [1].

The most common side effects of Vascepa are joint pain, swelling, and stiffness, as well as pain in the throat, back, and extremities. Other side effects may include flu-like symptoms, headache, and gastrointestinal issues such as diarrhea, nausea, and vomiting [2].

It is important to note that the side effects of generic versions of Vascepa may differ from those of the brand-name medication. However, since there are currently no generic versions of Vascepa available, it is not possible to provide information on the specific side effects of generic versions of this medication.

In August 2021, Amarin lost a patent appeal that would have protected Vascepa from generic competition until 2030. This means that generic versions of Vascepa may become available in the future [3].

In conclusion, the most common side effects of Vascepa include joint pain, swelling, and stiffness, as well as pain in the throat, back, and extremities, flu-like symptoms, headache, and gastrointestinal issues such as diarrhea, nausea, and vomiting. However, there are currently no generic versions of Vascepa available on the market, so it is not possible to provide information on the specific side effects of generic versions of this medication [1][2][3].
