I am unable to provide a specific answer to your question about how long someone has been taking Vascepa for allergies based on the sources provided. Vascepa is primarily used to treat high triglyceride levels in the blood, not allergies. It is important to consult with a healthcare professional for guidance on the appropriate use of Vascepa or any medication for allergies or other conditions.
