Atorvastatin, commonly known as Lipitor, is a medication used to lower cholesterol levels in the blood [1]. Like any medication, atorvastatin may cause side effects, but not everyone experiences them. Common side effects of atorvastatin include muscle pain, diarrhea, constipation, nausea, and stomach pain [2]. However, these side effects are usually mild and go away on their own after a short time.

When taken at lower doses, atorvastatin may have fewer side effects. According to the National Health Service (NHS), most people do not experience side effects when taking atorvastatin [3]. However, it is important to note that some people may still experience side effects, even at lower doses. The Mayo Clinic advises patients to talk to their doctor if they experience any side effects while taking atorvastatin, even if they are mild [2].

In conclusion, atorvastatin may cause side effects, but they are usually mild and go away on their own. When taken at lower doses, the risk of side effects may be reduced. However, it is important to talk to a doctor if any side effects are experienced while taking atorvastatin, even if they are mild.
