What the medication is used for

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 Dom- ATORVASTATIN.

Dom-ATORVASTATIN. is just part of the treatment your doctor will plan with you/your child to help keep you healthy. Depending on you/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.
