Lipitor is a brand name for the drug atorvastatin, which is a type of medication known as a statin. Statins are used to lower cholesterol levels in the blood, which can reduce the risk of heart attack and stroke. While statins are generally considered safe and effective, they can have side effects, including joint pain [2].

According to GoodRx [3], joint pain is a possible side effect of statins, including Lipitor. Joint pain can occur in any joint in the body, but it is most commonly reported in the knees, hips, and shoulders. The joint pain may be mild or severe, and it may come and go or be constant.

Drugwatch [2] also confirms that joint pain is a potential side effect of Lipitor. In some cases, joint pain may be accompanied by muscle pain, weakness, or tenderness. These symptoms may be a sign of a rare but serious condition called rhabdomyolysis, which can cause muscle damage and kidney failure.

While joint pain is a known side effect of Lipitor and other statins, it is important to note that not everyone who takes these medications will experience this side effect. If you are taking Lipitor and experience joint pain or any other symptoms, you should talk to your doctor. They can help determine if the symptoms are related to the medication and recommend appropriate treatment [2].
