Benefits of using this medication
Atorvastatin belongs to the group of medications known as HMG CoA reductase inhibitors (“statins”) or lipid metabolism regulators. It is used to treat people who have high cholesterol levels, including those people who have certain inherited cholesterol disorders. When you use this medication, you also need to make lifestyle changes, including switching to a diet low in fat and cholesterol, quitting smoking, and increasing the amount of exercise you do.
Atorvastatin works by blocking an enzyme that is used to make cholesterol in the liver. When that enzyme is blocked, less cholesterol is produced and the amount of cholesterol in the blood decreases. Atorvastatin lowers the level of total cholesterol and low density lipoprotein (LDL, or “bad” cholesterol), and raises high density lipoprotein (HDL, or “good” cholesterol) levels. Reduction of cholesterol levels in the blood has been shown to reduce the risks associated with heart disease, such as heart attack.
Atorvastatin is also used to reduce the risk of heart attack in people with high blood pressure who have at least 3 additional risk factors for heart disease but not experiencing symptoms associated with heart disease. The risk factors of heart disease for these individuals include:
- being male
- being 55 years old or older
- enlarged heart ventricles
- family history of heart disease
- specific abnormalities on an ECG
- the total cholesterol to HDL-cholesterol ratio that is greater than or equal to 6
- type 2 diabetes
- specific types of protein in the urine
- a specific type of protein in the urine
- being 55 years old or older
- disease of the retina
Atorvastatin may be used in addition to diet to reduce cholesterol for adolescents between 10 and 17 years of age with increased cholesterol levels and family history of early heart disease or 2 or more risk factors for cardiovascular disease.
The medication usually takes about 2 to 4 weeks to have a significant effect on the cholesterol level in your blood. After this time, your physician will likely send you for a blood test to check for changes in your cholesterol levels.

Alcohol: People who drink large quantities of alcohol should be closely monitored by their physician while they are taking this medication.
Cardiovascular: There is an increased risk of hemorrhagic stroke if atorvastatin is started within 6 months of having a stroke or transient ischemic attack (TIA). If you have a history of stroke or have had a recent stroke, discuss with your physician how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Diabetes: Atorvastatin may cause an increase in blood sugar levels and glucose tolerance may change. People with diabetes may find it necessary to monitor their blood sugar more frequently while using this medication.

Diet: Atorvastatin isn’t intended to be used alone to reduce high cholesterol levels. It is important that a cholesterol-reducing diet along with appropriate exercise be attempted before taking any medication and continued while taking medication.
Grapefruit juice: Taking atorvastatin and consuming grapefruit juice may result in an increased amount of atorvastatin in the body, and lead to side effects. If you regularly drink grapefruit juice, talk to your physician or pharmacist about whether you should change your diet.
Kidney function: If you have decreased kidney function or a history of kidney disease, you may be at an increased risk of developing muscle effects while taking atorvastatin.
