According to the sources provided, it is unclear whether Vascepa auto refills can be canceled at any time. The Drug Patent Watch website  provides information about the patent status of Vascepa but does not mention anything about the auto refill policy. The Vascepa website  offers information about the Vascepa Savings Card, which can help patients save on their Vascepa prescriptions, but it does not provide details about the auto refill policy or whether it can be canceled at any time. The GoodRx website  provides information about the cost of Vascepa and offers discounts, but it also does not mention anything about the auto refill policy. Therefore, it is recommended to contact the pharmacy or healthcare provider that manages the Vascepa prescription to inquire about the auto refill policy and how to cancel it if necessary.
