Lipitor is a brand name for the drug atorvastatin, which is used to treat high cholesterol levels. According to the Mayo Clinic [2], stomach discomfort is a common side effect of atorvastatin. This can include symptoms such as nausea, diarrhea, and stomach pain. However, it is important to note that not everyone who takes atorvastatin will experience these side effects, and the severity of symptoms can vary from person to person.

The drugpatentwatch.com [1] website provides information on the patent status of Lipitor but does not provide any information on its side effects. However, the drugwatch.com [3] website lists stomach pain as a potential side effect of Lipitor. This source also notes that other gastrointestinal symptoms, such as constipation and flatulence, may occur.

It is important to speak with a healthcare provider if you are experiencing stomach discomfort after taking Lipitor or any other medication. They can help determine the cause of your symptoms and recommend appropriate treatment options. Additionally, it is important to follow the prescribed dosage and to not stop taking Lipitor without consulting a healthcare provider.
