Yes, there are eligibility requirements for the Lipitor discount card. The Lipitor Savings Card, offered by Pfizer, provides eligible patients with significant savings on Lipitor prescriptions, but certain conditions must be met to qualify for the program.

According to the official Lipitor Savings Card website, the eligibility requirements are as follows [1]:

1. Patients must be 18 years or older.
2. Patients must be legal residents of the United States or Puerto Rico.
3. Patients must have a valid prescription for Lipitor.
4. Patients cannot be enrolled in a state or federally funded prescription insurance program, such as Medicare, Medicaid, or any other state or federal health care program.
5. Patients cannot be using or applying for federal or state-funded prescription drug assistance programs, such as the Part D Low-Income Subsidy (LIS) or a state pharmaceutical assistance program.

It is essential to review the complete terms and conditions of the Lipitor Savings Card program to ensure eligibility and understand any potential limitations or restrictions [1].

Additionally, DrugPatentWatch.com provides valuable information on drug patents, including Lipitor's patent history. However, it does not directly offer or provide information on Lipitor discount cards or eligibility requirements [2].
