According to the sources provided, Lipitor (atorvastatin) is generally cheaper than Crestor (rosuvastatin). The website GoodRx [2] shows that the average retail price for a 30-day supply of Lipitor is around $10, while Crestor is around $260. However, it is important to note that prices can vary depending on the pharmacy, location, and insurance coverage.

Additionally, the website Drug Patent Watch [1] indicates that Lipitor has been available as a generic drug since 2011, which has likely contributed to its lower cost. Crestor, on the other hand, did not have a generic version available until May 2016.

The website SingleCare [3] also notes that while both drugs are statins used to lower cholesterol levels, they have some differences in terms of effectiveness and potential side effects. Patients should consult with their healthcare provider to determine which medication is most appropriate for their individual needs.

In summary, based on the sources provided, Lipitor is generally cheaper than Crestor, but prices can vary depending on various factors. It is important for patients to consult with their healthcare provider and consider all factors when choosing a medication.
