How Does Crestor Work?
Cholesterol is a fatty substance, and high levels of cholesterol can lead to a condition called hypercholesterolaemia (sometimes known as hyperlipidaemia). Crestor works by reducing the amount of cholesterol that is produced and retained within the body’s blood vessels.
Reducing the amount of cholesterol produced helps to prevent cholesterol from building up in the walls of the arteries. This is important because having cholesterol in the arteries increases the risk of the arteries becoming blocked. When arteries become blocked, it can result in a stroke, heart attack, or damage to another organ in the body such as the kidneys.
Crestor can therefore reduce the risk of high cholesterol and some of its complications.
How is Crestor Taken?
Crestor is usually taken once a day. It can be taken at any time. It should be swallowed with some water, and can be taken with or without food.
For best results when taking Crestor, you should continue with a low cholesterol diet.
