As of November 2020, there is no generic version of Vascepa available on the market [2][3]. The drug is still under patent protection, which will expire in 2030 [1]. Despite attempts by several companies to challenge the patent, they have been unsuccessful in their efforts [2]. Therefore, Amarin Corporation, the manufacturer of Vascepa, is currently the only company that can produce and sell this medication [2]. It is important to note that even when the patent expires, it may take some time for a generic version of Vascepa to become available, as the FDA must first approve the generic drug before it can be sold to the public [3].
