The maximum Lipitor card discount percentage varies, but it can potentially reach up to 50% [1]. The Lipitor patient assistance program, also known as the Lipitor savings card, is designed to help eligible patients lower their out-of-pocket costs for this medication [1].

The Lipitor savings card can be used by patients with commercial insurance, those without insurance, and those in the Medicare Part D coverage gap, also known as the "donut hole" [1]. The card can be used for up to 24 fills per calendar year [1].

It is important to note that the actual discount percentage may vary based on several factors, such as the patient's insurance coverage, the prescribed dosage, and the location [1]. Patients can check the Lipitor website or contact the Lipitor support team to get the most accurate and up-to-date information on the maximum discount percentage they can receive [1].

In summary, the maximum Lipitor card discount percentage can be up to 50%, but it can vary based on several factors. Patients are encouraged to check the Lipitor website or contact the Lipitor support team for the most accurate information [1].
