According to the sources provided, there is a savings program available for Lipitor, but there is no information about a loyalty program.

The Lipitor website [2] offers a savings card for eligible patients that can help them save on their prescription. Patients can save up to $75 on each prescription fill, with a maximum annual savings of $1,500. The savings card is not available to patients who are enrolled in a state or federally funded prescription drug program.

However, there is no mention of a loyalty program on the Lipitor website or on the Drug Patent Watch [1] website, which provides information on the drug's patent status and expiration date.

The Krispy Kreme Rewards program [3] is not related to Lipitor and is not relevant to the question.

In summary, while there is a savings program available for Lipitor, there is no evidence of a loyalty program for the drug.
