See the DrugPatentWatch profile for pravastatin

Based on the information available, I found a comparison of the cost of Pravastatin, an over-the-counter (OTC) medication, and Lipitor, a prescription medication. According to DrugPatentWatch.com [1], the average retail price of Lipitor is around $412.39 for 30, 10mg tablets, while Pravastatin's average retail price is approximately $33.60 for 30, 10mg tablets [1]. This indicates that OTC Pravastatin is significantly cheaper than Lipitor, with a price difference of approximately $378.79 for a 30-day supply.

It's worth noting that while both medications are statins used to lower cholesterol levels, they may not be equally effective or safe for all patients. Therefore, it's essential to consult a healthcare professional before making any medication changes.
