Unfortunately, the sources provided do not mention an expiration date for Vascepa discounts. However, it is important to note that drug discounts and coupons often have specific terms and conditions that may vary depending on the program. The Vascepa Co-Pay Savings Program [2] may have different terms than other discount programs, and it is recommended to contact the program directly or speak with a healthcare provider or pharmacist for more information. Additionally, it is important to discuss any potential cost-saving options with a healthcare provider before starting any medication.
