Information for the Patient:

IMPORTANT: PLEASE READ: This leaflet is part of a “Product Monograph” published when CRESTOR was approved for sale in Canada and is designed specifically for Consumers. This leaflet is a summary and will not tell you everything about CRESTOR. Contact your doctor or pharmacist if you have any questions about the drug.

About This Medication:

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 lower the risk of heart attacks and strokes.

CRESTOR may be prescribed in children 10 to 17 years of age with heterozygous familial hypercholesterolemia (an inherited condition causing high cholesterol levels in the blood) to lower cholesterol levels. Children require supervision from adult care givers during treatment with CRESTOR (adult care givers should read the information provided below before their child begins treatment with CRESTOR).

What it does:

CRESTOR is the brand name for rosuvastatin that belongs to the class of medications 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 diet and exercise to help control the amount of cholesterol produced by the body.

CRESTOR can help your body:

  • Decrease LDL (bad) cholesterol and triglyceride levels.

  • Increase HDL (good) cholesterol levels.

  • Decrease the Total Cholesterol/HDL-Cholesterol Ratio (TC: HDL-C Ratio). The ratio represents the balance between good and bad cholesterol.

What is cholesterol?

Cholesterol is one of several fatty substances in the blood that the body needs to function. And it is important to our health. Our bodies use cholesterol in a number of ways; for example, to produce bile acids that help you digest fat.

High cholesterol levels may not make you feel or look sick. However, too much cholesterol in your blood can be unhealthy; it builds up on the artery walls and can lead to the signs and symptoms of cardiovascular disease (heart disease).

There are two very different types of cholesterol.

LDL cholesterol:

If levels of LDL cholesterol are too high, they can cause the gradual build-up of cholesterol called plaque on the walls of the blood vessels. Over time, this plaque can build up so much that it narrows the arteries. Narrow arteries can slow or block blood flow to vital organs like the heart and brain. Blocked blood flow can result in a heart attack or stroke.

HDL cholesterol:

HDL carries the LDL cholesterol away from the blood vessel walls to the liver, where it can be removed from the body. A higher level of HDL cholesterol is good.

Important cholesterol targets:

There are a few important measures that relate to your cholesterol. In addition to your HDL and LDL cholesterol, your doctor may also track your TC:HDL-C Ratio.

Lowering LDL cholesterol and Ratio:

There are many things you can do, depending on your health and lifestyle, to help lower LDL cholesterol, increase HDL cholesterol and lower your TC: HDL-C Ratio. Your doctor may recommend:

  • A change in your diet to control your weight and/or lower your cholesterol.

  • Exercise that is right for you.

  • Quitting smoking and avoiding smoky places.

  • Giving up alcohol or drinking less.

Follow your doctor’s instructions carefully.
