Lipitor is a medication used to lower cholesterol levels in the blood. It works by blocking an enzyme that is responsible for producing cholesterol in the liver [1]. While Lipitor is generally safe and effective, there are some potential side effects to be aware of.

One of the most serious side effects of Lipitor is muscle damage. This can lead to a condition called rhabdomyolysis, which can cause kidney damage or failure. Symptoms of muscle damage include weakness, pain, tenderness, or cramping [2].

Other potential side effects of Lipitor include liver damage, which can cause yellowing of the skin or eyes, dark urine, or upper abdominal pain. Lipitor can also cause digestive problems such as nausea, diarrhea, or constipation. Some people may experience headaches, dizziness, or insomnia [3].

It is important to note that not everyone will experience these side effects, and some people may experience no side effects at all. However, if you are taking Lipitor and experience any of these symptoms, it is important to speak with your doctor right away.
