According to the sources provided, there is no indication that Vascepa (icosapent ethyl) increases the side effects of alcohol. Vascepa is a prescription medication used to lower triglyceride levels in adults with high triglycerides. While Vascepa has a list of potential side effects, including headaches, joint pain, and stomach upset, none of the sources mention any interaction between Vascepa and alcohol that would increase the side effects of either substance. However, it is important to note that excessive alcohol consumption can have negative effects on health and may interact with other medications. It is always best to consult with a healthcare provider regarding any concerns about potential interactions between medications and alcohol.
