Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels in the blood. According to the Mayo Clinic [2], the most common side effects of Lipitor include muscle pain and damage, liver damage, digestive problems, and rash or flushing. However, these side effects are rare, and most people who take Lipitor do not experience any serious side effects. Additionally, Drugwatch [3] notes that Lipitor can also cause memory loss, confusion, and type 2 diabetes, although these side effects are even rarer. It is important to note that these side effects can vary from person to person and may not affect everyone who takes the medication. If you experience any side effects while taking Lipitor, it is important to speak with your doctor. They may be able to adjust your dosage or recommend a different medication to treat your high cholesterol levels.
