To apply for patient assistance with Lipitor, a cholesterol-lowering medication, several documents are typically required. While the exact requirements may vary depending on the specific patient assistance program, the following documents are generally needed:

1. Proof of U.S. residency: This can include a driver's license, state ID, or utility bill.
2. Proof of income: This can include tax returns, pay stubs, or a letter from your employer stating your income. Some programs may require additional documentation, such as proof of unemployment or disability benefits.
3. Insurance information: This includes your insurance card and any relevant explanation of benefits (EOB) forms.
4. Prescription information: This includes the name of the medication, dosage, and prescribing physician.
5. Completed application form: Most patient assistance programs provide an application form that must be completed and signed.

It's important to note that Lipitor, also known as atorvastatin, is manufactured by Pfizer and its patents have expired. Therefore, there are generic versions of the medication available that may be more affordable than the brand-name version. However, patient assistance programs may still be available for the brand-name version.
