Based on the information provided, I cannot definitively confirm whether Lipitor is covered by Walmart's Prescription Savings Program. However, I can provide some context that may help answer your question.

Walmart's Prescription Savings Program, also known as the $4 Generic Prescription Program, covers a list of generic drugs, including four categories: diabetic supplies, hypertension, mental health, and preventive care [1]. This program aims to make certain medications more affordable for customers [1].

Lipitor is a brand-name drug used to treat high cholesterol, and its active ingredient is atorvastatin [2]. According to the information available, Walmart's program does not explicitly list Lipitor or its generic equivalent, atorvastatin, among the covered drugs [1]. However, it is essential to note that Walmart's program primarily focuses on specific generic drugs [1].

It is advisable to double-check Lipitor's coverage with Walmart's pharmacy or customer service directly, as the program's details and covered medications can change over time [1]. Additionally, alternative options for cost savings on Lipitor may include using discount cards or coupons from websites like GoodRx [3].

In summary, while Lipitor is not explicitly listed as a covered drug in Walmart's Prescription Savings Program, it is always best to confirm coverage directly with Walmart or explore alternative cost-saving options [2][3].
