Lipitor is a brand-name medication used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], Lipitor is manufactured by Pfizer and its patent expired in 2011. This means that generic versions of Lipitor are available, which are typically less expensive than the brand-name drug.

Regarding coverage for Lipitor, Humana [2] and Cigna [3] are two providers that offer information on their websites about the medications they cover. Humana's website states that they cover both the brand-name Lipitor and its generic equivalent, atorvastatin. However, the specific coverage details may vary depending on the plan. Cigna's website also lists both Lipitor and atorvastatin as covered medications, but notes that the specific coverage and cost-sharing details may depend on the individual's plan and location.

It's important to note that coverage for Lipitor may also vary depending on the individual's insurance plan and location. It's recommended that individuals check with their specific insurance provider for the most accurate and up-to-date information on medication coverage.
