As an AI language model, I haven't tried switching to Lipitor or any other medication. However, I can provide you with information based on the sources you provided.

Lipitor is a brand-name medication that contains the active ingredient atorvastatin. It is a type of medication called a statin that is used to lower cholesterol levels in the blood [1]. Lipitor was approved by the FDA in 1996 and has been available as a generic medication since 2011 [1].

According to the National Center for Biotechnology Information, atorvastatin is effective in reducing low-density lipoprotein (LDL) cholesterol levels and preventing cardiovascular events in patients with and without pre-existing cardiovascular disease [2]. However, like all medications, Lipitor can cause side effects. Some of the most common side effects of statins include muscle pain, liver damage, and gastrointestinal problems [3].

If you are considering switching to Lipitor or any other medication, it is important to talk to your healthcare provider. They can help you weigh the potential benefits and risks of the medication and determine if it is the right choice for you.
