Yes, you can switch from brand name Lipitor to generic Lipitor, also known as atorvastatin. The active ingredient, atorvastatin, is the same in both brand name and generic versions [1].

The U.S. Food and Drug Administration (FDA) requires that generic drugs have the same quality, strength, purity, and stability as brand-name drugs [2]. This means that generic Lipitor works in the same way and provides the same clinical benefit as Lipitor [1].

However, it's important to note that there may be differences in the inactive ingredients, such as binders and fillers, between brand name and generic versions [3]. These differences may cause minor variations in the drug's taste, color, or shape [3]. If you have any concerns about switching to a generic medication, it's best to discuss it with your healthcare provider or pharmacist [1].

According to DrugPatentWatch.com, Lipitor's patent expired in November 2011 [4]. This means that other manufacturers were able to produce and market generic versions of Lipitor after this date.

In summary, you can switch from brand name Lipitor to generic Lipitor. Both versions contain the same active ingredient and are required to have the same quality, strength, purity, and stability. However, there may be differences in inactive ingredients. It's always best to discuss any concerns with your healthcare provider or pharmacist.
