🔬 What Is Atorvastatin?
Atorvastatin is a statin medication used to lower cholesterol levels — specifically LDL (“bad”) cholesterol and triglycerides — while slightly increasing HDL (“good”) cholesterol. It is also prescribed to reduce the risk of cardiovascular disease (CVD), including heart attacks and strokes, in people who are at high risk.
Common Brand Name: Lipitor.
Common Dosages: 10 mg, 20 mg, 40 mg, and 80 mg tablets.
🔬 How Atorvastatin Works
Atorvastatin works by blocking an enzyme in the liver called HMG-CoA reductase. This enzyme is responsible for producing cholesterol. By blocking it, the liver produces less cholesterol and also removes more LDL cholesterol from the blood.
⚠️ What You Should Know About Side Effects
Like all medications, atorvastatin can cause side effects. The most common include muscle pain, digestive issues, and mild liver enzyme changes. Serious side effects are rare but can include liver damage and muscle breakdown.
Important: If you experience unexplained muscle pain, weakness, or dark urine, contact your doctor immediately. These can be signs of a rare but serious condition called rhabdomyolysis.
