Lipitor, also known as atorvastatin, is a medication that is used to lower cholesterol levels in the body [1]. According to the Mayo Clinic [2], some of the common side effects of Lipitor include muscle aches and pains, diarrhea, constipation, and nausea. However, these side effects are usually mild and go away on their own.

In rare cases, Lipitor can cause serious side effects such as liver damage, muscle breakdown, and an increased risk of diabetes [2]. If you experience any of these symptoms, it is important to contact your healthcare provider immediately.

Medical News Today [3] also notes that Lipitor can interact with other medications, so it is important to inform your healthcare provider of all the medications you are taking before starting Lipitor.

It is important to note that not everyone who takes Lipitor will experience side effects, and the benefits of the medication often outweigh the risks [2]. However, if you have any concerns about taking Lipitor or experience any side effects, it is important to speak with your healthcare provider.
