Vascepa is a prescription drug used to lower triglyceride levels in adults. The drug is manufactured by Amarin Pharma and was approved by the FDA in 2012 [2]. Vascepa is still under patent protection until 2030 [1]. A generic version of Vascepa was approved by the FDA in 2020, but it is not yet available on the market [3]. It is recommended to consult with a healthcare provider or pharmacist for more information on the availability and expiration of the Vascepa coupon.
