Vascepa, a prescription medication containing the active ingredient icosapent ethyl, is commonly used to lower triglyceride levels in adults. While it is generally well-tolerated, there are some potential side effects associated with its use. According to information from Drug Patent Watch and Vascepa's official website, common side effects of Vascepa may include joint pain, swelling, and stiffness, as well as pain in extremities. Additionally, Vascepa may lead to an increase in liver enzymes, which can be monitored through regular blood tests. It is important to note that not all individuals will experience these side effects, and some may have no side effects at all.

For a more comprehensive list of potential side effects and to understand how Vascepa may interact with other medications or medical conditions, it is advisable to consult a healthcare provider. They can provide personalized guidance based on an individual's specific health profile.
