About This Medication


Your doctor has prescribed these pills to help lower your cholesterol or other fats in the blood (such as triglycerides) and to prevent cardiovascular disease such as heart attacks. High levels of cholesterol and other fats can cause heart disease by clogging the blood vessels that feed blood and oxygen to the heart.

Children 10-17 years old with heterozygous familial hypercholesterolemia (high cholesterol inherited from one of the parents) and a family history of cardiovascular disease or 2 or more risk factors of cardiovascular disease, as determined by your doctor, can also benefit from taking GDATORVASTATIN.

GD-ATORVASTATIN is just part of the treatment your doctor will plan with you/your child to help keep you healthy. Depending on your/your child’s health and lifestyle, your doctor may recommend:

  • a change in diet to control weight and reduce cholesterol, reduce intake of saturated fats and increase fiber
  • exercise that is right for you/your child
  • quitting smoking or avoiding smoky places
  • giving up alcohol or drinking less

Follow your doctor’s instructions carefully.


GD-ATORVASTATIN belongs to the class of medicines known as “statins”, more specifically called HMG-CoA reductase inhibitors. HMG-CoA reductase is an enzyme involved in regulating cholesterol levels in your body. Statins are used along with changes to exercise and diet to help control the amount of cholesterol produced by the body.


  • Decrease LDL (bad) cholesterol, triglyceride levels and other lipids /fats in the blood.
  • Increase HDL (good) cholesterol.
  • Decrease the Total Cholesterol HDL-Cholesterol Ratio (TC:HDL-C Ratio). This ratio represents the balance between bad and good cholesterol.

GD-ATORVASTATIN also reduces the risk of heart attacks and strokes in people with multiple risk factors for coronary heart disease such as high blood pressure and diabetes. When used by people who have suffered a heart attack in the past, GDATORVASTATIN reduces the risk of having another heart attack.

GD-ATORVASTATIN is only available by prescription after seeing a doctor.

Proper Use of This Medication

We often cannot see or feel the problems that high cholesterol causes until a lot of time has passed. That's why it is important to take these pills just as prescribed. You/your child and your doctor will be watching your/your child’s cholesterol levels to get them down to a safe range. Here are some important tips.

  • Follow the plan that you/your child and your doctor make for diet, exercise and weight control.
  • Take GD-ATORVASTATIN as a single dose. It does not matter if GD-ATORVASTATIN is taken with food or without food, but it should not be taken with grapefruit juice. Your doctor will usually tell you/your child to take it in the evenings.
  • Do not change the dose unless directed by a doctor.
  • If you/your child get sick, have an operation, or need medical treatment, inform your doctor or pharmacist that you/your child are taking GD-ATORVASTATIN.
  • If you/your child have to take any other medicine - prescription or non-prescription - while taking GDATORVASTATIN, talk to your doctor or pharmacist first.
  • If you/your child have to see a different doctor for any reason, be sure to inform him/her that you/your child are/is taking GD-ATORVASTATIN.
  • GD-ATORVASTATIN was prescribed for you/your child only. Don't give these pills to anyone else.
