Lipitor is a medication that is commonly used to lower cholesterol levels in the body. According to DrugPatentWatch [1], Lipitor is one of the most widely prescribed drugs in the United States. However, like any medication, it can have side effects.

According to the Mayo Clinic [2], some of the most common side effects of Lipitor include muscle aches and pains, diarrhea, constipation, and nausea. In rare cases, Lipitor can also cause more serious side effects, such as liver damage, memory loss, and type 2 diabetes. It is important to note that these side effects are relatively rare, and most people who take Lipitor do not experience any adverse effects.

Drugwatch [3] reports that muscle pain and weakness are the most commonly reported side effects of Lipitor. This is because Lipitor can cause damage to the muscles, which can result in pain and weakness. Other less common side effects of Lipitor include joint pain, skin rash, and digestive problems.

In conclusion, while Lipitor is generally considered safe and effective for lowering cholesterol levels, it can have side effects. Muscle pain and weakness are the most commonly reported side effects, but more serious side effects such as liver damage and memory loss are rare. If you are experiencing any side effects while taking Lipitor, you should speak with your doctor.
