Vascepa, a prescription medication containing icosapent ethyl, is primarily used to reduce high triglyceride levels in the blood. While it is generally well-tolerated, like all medications, it can cause side effects in some individuals. The severity of allergic reactions to Vascepa can vary from mild to severe. Symptoms of an allergic reaction may include rash, itching, swelling, dizziness, and difficulty breathing. If you experience any of these symptoms after taking Vascepa, it is important to seek medical attention immediately. It is crucial to consult with a healthcare provider before starting any new medication to discuss potential side effects and allergic reactions.
