Based on the information available, it is difficult to provide a definitive answer regarding the indefinite use of the Lipitor discount card. The availability of such discounts is often subject to change and can depend on various factors, including the patent status of the drug.

Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels. According to DrugPatentWatch.com [1], the patent for Lipitor expired in November 2011 in the United States. After a patent expires, generic versions of the drug become available, which can increase competition and potentially lower costs for consumers.

However, the existence of a discount card and its terms of use, such as whether it can be used indefinitely, are typically determined by the manufacturer, pharmacy, or the program offering the discount. Therefore, it is recommended to check the specific terms and conditions associated with the Lipitor discount card from the relevant source.

In summary, while the patent for Lipitor has expired, allowing for the possibility of lower costs due to generic competition, the use of a Lipitor discount card indefinitely depends on the specific terms and conditions set by the program offering the discount.
