Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the body. It belongs to a class of drugs called statins. According to Drug Patent Watch [1], the most common side effects of Lipitor include muscle pain, weakness, and liver problems. However, there are several substitutes for Lipitor that can also lower cholesterol levels, with different side effect profiles.

One alternative to Lipitor is ezetimibe, which works by blocking the absorption of cholesterol in the intestines. According to the British Heart Foundation [2], the most common side effects of ezetimibe are diarrhea, abdominal pain, and muscle pain. Another option is bile acid sequestrants, such as cholestyramine and colestipol, which work by binding to bile acids in the intestines and preventing their reabsorption. The British Heart Foundation [2] notes that the most common side effects of bile acid sequestrants are constipation, bloating, and gas.

Another alternative to Lipitor is a PCSK9 inhibitor, such as evolocumab and alirocumab. These medications work by blocking a protein that prevents the liver from removing LDL cholesterol from the blood. According to GoodRx [3], the most common side effects of PCSK9 inhibitors include injection site reactions, flu-like symptoms, and allergic reactions.

It is important to note that all medications have potential side effects, and the benefits and risks should be discussed with a healthcare provider. In addition, lifestyle changes such as a healthy diet and regular exercise can also help lower cholesterol levels and may be recommended in conjunction with medication.
