Lipitor 40 mg: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions

What Is Lipitor 40 mg?

Lipitor 40 mg is a prescription medicine containing atorvastatin calcium, a statin medication used to lower cholesterol and reduce the risk of cardiovascular disease. It helps decrease levels of low-density lipoprotein (LDL) cholesterol (“bad” cholesterol) and triglycerides while increasing high-density lipoprotein (HDL) cholesterol (“good” cholesterol).

Lipitor is commonly prescribed alongside a heart-healthy diet, regular exercise, and other lifestyle changes to help improve cholesterol levels and protect against serious cardiovascular events such as heart attack and stroke.

Lipitor is available in several tablet strengths, including:

• 10 mg
• 20 mg
• 40 mg
• 80 mg

How Lipitor Works

Lipitor belongs to a group of medicines known as HMG-CoA reductase inhibitors (statins).

It works by:

• Blocking an enzyme involved in cholesterol production in the liver.
• Lowering LDL (“bad”) cholesterol.
• Reducing triglyceride levels.
• Increasing HDL (“good”) cholesterol.
• Helping stabilize fatty plaques in blood vessels.
• Lowering the risk of heart attack, stroke, and other cardiovascular complications.

Because cholesterol production is reduced, the liver also removes more LDL cholesterol from the bloodstream.
