What is Crestor

Crestor lowers the amount of cholesterol that ends up in your bloodstream, and your arteries. Crestor raises the amount of HDL (good cholesterol) and lowers LDL (bad cholesterol). Crestor does this with the cholesterol in our blood which is actually made in our livers. It blocks an enzyme i the liver that produces that bad cholesterol while raising the good cholesterol. It actually lowers the amount of cholesterol that ends up in your blood stream. It is prescribed by your doctor to treat high cholesterol.

How to use Crestor

It is usually ordered once a day and you can take it at any time (try and stick to the same time each day though), with or without food. Some doctors will tell you to take it daily at bedtime as it is thought that the body makes cholesterol while you sleep. If you miss a dose take it as soon as you remember unless it it almost time to take your next dose. It should be taken with a full glass of liquid. Store it away from heat and moisture. If for some reason you think you may have overdosed on Crestor get medical attention.

About Crestor

What Crestor is used for

Your doctor has prescribed these pills to help lower your cholesterol or other fats in the blood (such as triglycerides) which may prevent cardiovascular disease such as heart attacks.

What Crestor 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.

  • Warfarin (or any other drug for thinning the blood).

  • Ritonavir combined with another protease inhibitor (for control of HIV infection).

  • Antacids (frequent use) and CRESTOR should be taken 2 hours apart.

I switched to Crestor two years ago, which is right about the time when I started buying my medication online. I like how you offer refill reminders, and that I can find what I'm looking for on your website.
