According to the Lipitor prescribing information and patent expiration status available on DrugPatentWatch.com, at the time of Lipitar's original release, Pfizer, the manufacturer, offered patient assistance programs and rebates to eligible patients taking Lipitor [1]. These programs may have included rewards or discounts for refills, but details on those specific offerings are not readily available.

However, it appears that there might have been certain restrictions or limitations on redeeming these rewards. For instance, the rebates and discounts were only available for 'eligible patients' who were prescribed Lipitor for an FDA-approved indication and met specific income requirements [2].

Additionally, patients may have been required to enroll in Pfizer's patient assistance program to receive these rewards, and some restrictions might have applied to the redemption of rewards, such as limitations on the number of refills or the amount of reward per refill [3].

Please note that these programs and rewards may have been altered or discontinued since their original announcement.

For the most up-to-date and accurate information regarding any current restrictions on redeeming rewards, patients should contact their healthcare provider or the Pfizer patient assistance program directly.
