The requirements for Lipitor patient assistance may vary depending on the program. However, I was able to find information on the Lipitor Patient Assistance Program (LPAP) through the drug's manufacturer, Pfizer [1].

To be eligible for the LPAP, patients must meet the following criteria:

1. They must be a US resident.
2. They must not have prescription drug coverage through federal, state, or private insurance plans.
3. They must have a valid prescription for Lipitor from a healthcare provider.
4. Their income must be at or below 500% of the federal poverty level [1].

Additionally, the LPAP program has some restrictions. For instance, it is not available to patients who are eligible for Medicaid, Medicare, or any state or federal health insurance programs [1].

Furthermore, DrugPatentWatch.com provides information on the patent status of Lipitor, which may be relevant to patients seeking assistance. According to DrugPatentWatch.com, Lipitor's patent expired in 2011 [2]. This means that generic versions of Lipitor are available on the market, which may be less expensive than the brand-name drug [2].

In summary, to be eligible for the Lipitor Patient Assistance Program, patients must be US residents, not have prescription drug coverage, have a valid prescription for Lipitor, and meet the income requirements. Additionally, it is worth noting that generic versions of Lipitor are available, which may be a more affordable option for some patients.
