The duration of the Vascepa discount is not explicitly mentioned in the provided sources. However, we can gather some information from the sources to provide a comprehensive answer.

Vascepa is a prescription medication that contains the active ingredient icosapent ethyl. It is primarily used to reduce triglyceride levels in adults with severe hypertriglyceridemia [3]. According to the sources, Vascepa is a brand-name drug that was granted FDA approval in 2012 [1].

The first source, DrugPatentWatch, provides information about the patent status of drugs. It indicates that the patent for Vascepa is set to expire in April 2030 [1]. However, it is important to note that the expiration of a drug patent does not necessarily mean an immediate end to any associated discounts or pricing changes.

The second source, the official website of Vascepa, does not specifically mention the duration of any discount programs. However, it provides information about a savings card program called Vascepa Co-Pay Savings Program. This program is designed to help eligible patients save on their out-of-pocket costs for Vascepa prescriptions. Patients can enroll in this program and receive a discount on their prescription costs [2]. The website does not specify the duration of this program, so it is recommended to contact the manufacturer or consult with a healthcare professional for the most up-to-date information on the duration of the Vascepa Co-Pay Savings Program.

The third source, Drugs.com, provides a comparison between Vascepa and another medication called Lovaza. It mentions that Lovaza is the first FDA-approved prescription omega-3 fatty acid product, and its patent expired in 2013 [3]. Although this information is not directly related to the duration of the Vascepa discount, it highlights that the expiration of a drug patent does not necessarily result in an immediate end to discounts or changes in pricing.

In conclusion, while the provided sources do not explicitly state the duration of the Vascepa discount, it is important to note that the patent for Vascepa is set to expire in April 2030 [1]. Additionally, the official website of Vascepa mentions a savings card program, but the duration of this program is not specified [2]. To obtain the most accurate and up-to-date information regarding the duration of the Vascepa discount, it is recommended to contact the manufacturer or consult with a healthcare professional.
