Lipitor is a brand name for the drug atorvastatin, which is a statin medication used to lower cholesterol levels in the blood. According to the Mayo Clinic [2], the usual starting dose of atorvastatin is 10-20 mg once daily, and the maximum dose is 80 mg once daily. The dosage may vary depending on individual circumstances, such as age, gender, and other medical conditions.

It is important to note that taking Lipitor may have side effects, as mentioned by the Mayo Clinic [2]. Some common side effects include muscle pain, liver damage, and digestive problems. In rare cases, it may also cause serious side effects such as muscle breakdown, kidney failure, and memory loss. Therefore, it is important to consult with a healthcare provider before taking Lipitor, especially if you have a history of liver problems or are taking other medications that may interact with atorvastatin.

In conclusion, the dosage of Lipitor or atorvastatin may vary depending on individual circumstances and should be determined by a healthcare provider. It is important to be aware of the potential side effects and to consult with a healthcare provider before taking this medication. The cost of atorvastatin and its generic versions may also vary, and GoodRx offers coupons and discounts that can help reduce the cost.
