Atorvastatin, commonly known as Lipitor, is a medication used to lower cholesterol levels in the blood. According to the Mayo Clinic, the common side effects of atorvastatin include diarrhea, joint pain, and urinary tract infections [2]. However, it is important to note that not all people experience side effects and some may experience different side effects. The severity of the side effects may also vary from person to person.

Regarding the new Lipitor dosage, the sources do not provide specific information about a new dosage. However, it is important to consult with a healthcare provider about any changes in medication dosage. They can provide information about potential side effects and monitor for any adverse reactions.

It is also important to note that while atorvastatin is generally well-tolerated, it may interact with other medications. According to GoodRx, atorvastatin may interact with medications such as clarithromycin, cyclosporine, and gemfibrozil, among others [3]. It is important to inform healthcare providers about all medications being taken to avoid potential interactions.

In conclusion, while atorvastatin may cause side effects, the severity and type of side effects may vary from person to person. It is important to consult with a healthcare provider about any changes in medication dosage and potential interactions with other medications.
