Vascepa is a prescription medication used to treat high levels of triglycerides in the blood. It contains the active ingredient icosapent ethyl, which is a type of omega-3 fatty acid. While Vascepa is generally well-tolerated, there are some common side effects associated with its use.

According to Everyday Health [2], some of the most common side effects of Vascepa include joint pain, swelling in the hands or feet, and a skin rash. Other possible side effects include headache, dizziness, and an upset stomach. Some patients may also experience back pain, muscle pain, or a feeling of weakness.

The Drug Patent Watch [1] also lists some potential side effects of Vascepa, including nausea, diarrhea, and constipation. Patients may also experience flu-like symptoms such as fever, chills, and sore throat. In rare cases, Vascepa may cause an allergic reaction, which can manifest as hives, difficulty breathing, or swelling of the face, lips, tongue, or throat.

It is important to note that not all patients will experience side effects from Vascepa, and the severity of side effects can vary from person to person. If you experience any unusual symptoms while taking Vascepa, it is important to contact your doctor right away.
