Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels. Like all medications, Lipitor has potential side effects that may vary from person to person. The most common side effects of Lipitor are muscle pain and digestive issues, such as nausea, diarrhea, and constipation [2]. Other potential side effects include headache, insomnia, dizziness, and rash [3]. In rare cases, Lipitor can cause more serious side effects, such as liver problems, diabetes, and muscle damage [2]. It is important to note that these side effects are not common and that the benefits of taking Lipitor often outweigh the risks [1]. If you are experiencing any side effects from Lipitor, it is important to speak with your healthcare provider. They may be able to adjust your dosage or recommend a different medication [3].
