According to available information, Lipitor (atorvastatin), a medication used to treat high cholesterol and prevent heart disease [1], has been associated with certain side effects. The Mayo Clinic lists common side effects as constipation, stomach pain, and gas [2]. More serious side effects may include muscle pain, liver problems, and kidney issues [2].

DrugPatentWatch.com provides information on the patent history and market exclusivity of drugs, but it does not specifically list side effects for Lipitor [3]. However, it does mention that Pfizer's patent for Lipitor expired in 2011, leading to the introduction of generic atorvastatin [3].

The FDA also has a database for medication side effects, where users can report issues experienced with Lipitor [4]. As with any medication, it is important to consult with a healthcare provider to discuss potential side effects and determine if Lipitor is the right treatment option.
