Lipitor is the commercial name for atorvastatin, a medicine generally prescribed to lower blood cholesterol and triglyceride levels. Lipitor reduces the amount of LDL ‘bad’ cholesterol and increases the amount of HDL ‘good’ cholesterol in the body. Thus, it basically functions to minimize heart-related complications and manage existing heart conditions.

Apart from this basic function, Lipitor may also be given to people with type 2 diabetes, hypertension, history of smoking, or other conditions that increase the risk of developing heart disease.


Lipitor belongs to a class of drugs called statins. These are widely prescribed in the US, and Lipitor is among the top-selling drugs of all time – above 29 million individuals in the US have been prescribed the drug. Pfizer manufactures Lipitor, after receiving approval by the Food And Drug Administration (FDA) in 1996.

Risk Of Diabetes

Clinical studies show using Lipitor represents an increased risk for developing type 2 diabetes. In 2014, Pfizer had to face lawsuits by women who claimed that the drug gave them type 2 diabetes. The company denied liability stating that this must have been due to the women having other risk factors for the disease, such as hypertension. Nevertheless, FDA called to include in the label of the drug warnings about elevating blood sugar levels.

A study based on over 470,000 patients recently treated with statins revealed that Lipitor did indeed present a risk for diabetes. However, this risk is only prevalent in certain groups, such as the elderly, females and Asians.

Risk Of Myopthay And Kidney Failure

When taking Lipitor, there is a possible risk of developing myopathy – a disease where muscle fibers fail to function normally. If you experience tenderness, pain or weakness in muscles, along with fever, report to your doctor immediately.

In rare cases, Lipitor might cause skeletal muscles to break down, resulting in kidney failure. If you experience unexplained muscle weakness, fatigue and dark-colored urine, contact your doctor right away.

Pregnancy And Lipitor Effects

Statins generally put the fetus at risk and should be avoided during pregnancy. Women of childbearing age using Lipitor should use some method of birth control to avoid a pregnancy. Also, women who are breastfeeding should avoid the drug, since it can pass via breast milk to the infant.
