Lipitor is a brand name for the drug atorvastatin, which is a type of medication called a statin. Statins are used to lower cholesterol levels in the blood [2]. According to the Mayo Clinic, one of the side effects of statins is weight gain [3]. However, weight loss is not typically associated with Lipitor or other statins [2][3].

In fact, some studies have suggested that statins may actually cause weight gain in some people [2]. This could be due to the fact that statins can cause muscle pain and weakness, which may lead to decreased physical activity and weight gain [2].

It is important to note that weight gain or loss is not a primary indication for the use of Lipitor or other statins [2]. These medications are primarily used to lower cholesterol levels and reduce the risk of heart disease and stroke [2][3].

In summary, while weight gain is a possible side effect of Lipitor and other statins, weight loss is not typically associated with these medications. It is important to discuss any concerns about weight changes with a healthcare provider [2][3].
