As an AI language model, I do not consult with doctors or prescribe medication. However, I can provide information on Lipitor based on the sources you provided.

Lipitor is a medication that is used to lower cholesterol levels in the blood, which can reduce the risk of heart attack, stroke, and other cardiovascular diseases. It works by blocking an enzyme in the liver that is responsible for producing cholesterol [2]. Lipitor is available in tablet form and is typically taken once a day, with or without food [2].

Like all medications, Lipitor can cause side effects. Some common side effects include muscle pain, diarrhea, and joint pain [2]. More serious side effects, such as liver problems and muscle damage, are less common but can occur [3]. Patients taking Lipitor should be aware of these potential side effects and should consult with their doctor if they experience any symptoms.

It is important to note that Lipitor is a prescription medication and should only be taken under the supervision of a healthcare provider. Patients should discuss their medical history and any other medications they are taking with their doctor before starting Lipitor [2].
