The sources provided do not indicate any restrictions on the Lipitor discount card. The Lipitor website offers a savings card that can be used for eligible patients to reduce their out-of-pocket expenses on Lipitor prescriptions [2]. GoodRx also confirms that the Lipitor savings card can be used by patients with or without insurance, and it can be used to save up to $75 per prescription [3]. However, it is important to note that the availability of the discount card may vary depending on the location and the pharmacy, and it may not be combined with other offers or discounts. It is also recommended to consult with a healthcare provider or pharmacist for more information on the use of the Lipitor discount card.
