Lipitor, also known as atorvastatin, is a medication that is used to lower cholesterol levels in the body. While it is generally considered safe and effective, there are some potential side effects to be aware of.

According to DrugPatentWatch [1], some of the most common side effects of Lipitor include headache, muscle pain, diarrhea, and nausea. These side effects are usually mild and go away on their own, but if they persist or become severe, it is important to speak with a doctor.

In addition to these common side effects, there are some more serious side effects that can occur with Lipitor. According to DrugWatch [2], these can include liver damage, muscle damage, and an increased risk of diabetes. It is important to note that these side effects are rare, but they can be serious. If you experience any unusual symptoms while taking Lipitor, such as dark urine, yellowing of the skin or eyes, or unexplained muscle pain, it is important to seek medical attention right away.

The Mayo Clinic [3] also notes that there is a small risk of developing cognitive problems, such as memory loss or confusion, while taking statins like Lipitor. However, this risk is generally considered to be very low.

In conclusion, while Lipitor is generally considered safe and effective for lowering cholesterol levels, there are some potential side effects to be aware of. If you experience any unusual symptoms while taking Lipitor, it is important to speak with a doctor right away.
