Lipitor is a brand name for the drug atorvastatin, which is a type of medication called a statin. Statins are used to lower cholesterol levels in the blood, which can help reduce the risk of heart disease and stroke [2].

If you are currently taking medication, it is important to speak with your doctor before starting Lipitor or any other new medication. This is because some medications can interact with each other and cause harmful side effects.

According to DrugPatentWatch [1], the patent for Lipitor expired in 2011, which means that generic versions of the drug are now available. This may make the medication more affordable for some people.

The Mayo Clinic [2] notes that statins like Lipitor are generally well-tolerated, but they can cause side effects in some people. Common side effects include muscle pain and weakness, digestive problems, and an increased risk of developing type 2 diabetes. Rare but serious side effects can include liver damage and muscle breakdown.

The Centers for Disease Control and Prevention [3] recommends that people with high cholesterol levels make lifestyle changes, such as eating a healthy diet and getting regular exercise, in addition to taking medication if prescribed by a doctor.

In summary, Lipitor is a medication used to lower cholesterol levels in the blood. It is important to speak with a doctor before starting Lipitor or any other new medication, as some medications can interact with each other. Lipitor can cause side effects in some people, and lifestyle changes are also important for managing high cholesterol levels.
