It is important to note that the specific eligibility requirements for Lipitor rebates may vary depending on the program or pharmacy, and patients are encouraged to check with the program or pharmacy for the most up-to-date information.

In summary, Lipitor rebates are available to patients with a valid prescription for Lipitor, who are not eligible for government-funded healthcare programs and have a valid email address [1]. The availability and cost of Lipitor may be affected by the patent status of the drug [2].
