Vascepa is a prescription medication that contains the active ingredient icosapent ethyl, which is used to treat high levels of triglycerides in the blood. The recommended dose of Vascepa is two capsules (1 gram) twice daily with food [3]. The duration of treatment with Vascepa depends on the patient's medical condition and response to the medication. It is essential to continue taking Vascepa as prescribed by a healthcare provider, even if symptoms improve.

According to Drug Patent Watch [1], Vascepa's patent will expire in 2030, and there are no generic versions of the medication available in the market. This means that the availability of Vascepa may not be affected by patent expiration, and patients can continue taking the medication as prescribed.

Healthline [2] mentions that patients should not stop taking Vascepa without consulting their healthcare provider. Stopping the medication suddenly can increase the risk of heart attack, stroke, and other complications. Patients should inform their healthcare provider if they experience any side effects or have concerns about taking Vascepa.

In summary, the recommended dose of Vascepa is two capsules (1 gram) twice daily with food, and the duration of treatment depends on the patient's medical condition and response to the medication. Patients should not stop taking Vascepa suddenly without consulting their healthcare provider. The availability of Vascepa may not be affected by patent expiration.
