Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. According to Drug Patent Watch [1], Lipitor is a brand name drug that has been on the market since 1996 and is one of the most commonly prescribed statins in the United States. While statins are generally effective in reducing cholesterol levels, they can also cause side effects in some people.

According to the Mayo Clinic [2], some of the common side effects of statins, including Lipitor, are muscle pain and damage, liver damage, digestive problems, and increased blood sugar levels. However, the risk of these side effects is generally low and can be managed with regular monitoring and dose adjustments.

In terms of which statin has the least amount of side effects, BuzzRX [3] suggests that there is no clear winner. The article notes that different people may react differently to different statins, and that the best option for an individual will depend on their specific health needs and risk factors. However, the article does note that some studies have suggested that Lipitor may be less likely to cause muscle pain and damage than other statins.

Overall, while Lipitor can cause side effects in some people, the risk of these side effects is generally low and can be managed with regular monitoring and dose adjustments. While there is no clear winner in terms of which statin has the least amount of side effects, some studies suggest that Lipitor may be less likely to cause muscle pain and damage than other statins. It is important for individuals to discuss their specific health needs and risk factors with their healthcare provider to determine the best option for them.
