Crestor belongs to a group of medications known as HMG CoA reductase inhibitors or “statins”. Crestor is prescribed to treat high or unhealthy cholesterol levels, as these may lead to dangerous cardiovascular problems like heart attack or stroke. It does so by increasing stores of “good” HDL (high density lipoprotein) cholesterol, while simultaneously decreasing “bad” LDL (low density lipoprotein) cholesterol and triglycerides. Triglycerides are a kind of fat. Rosuvastatin, the active ingredient in Crestor, blocks the activity of a liver enzyme called HMG-CoA reductase. Because this enzyme is involved in LDL production, the blockage of HMG-CoA reductase reduces the amount of cholesterol in the liver cells, which prompts those cells to draw LDL from the blood. This leads to reduced cholesterol levels. Crestor also slows the accumulation of plaque on the arteries and reduces triglyceride production in the blood.
It is important that you avoid alcoholic drinks and high-fat or high-cholesterol foods while taking brand name or generic Crestor to prevent negative interactions and reactions. Certain medications should also be avoided, including blood thinners, anti-fungal drugs, and HIV or AIDS medications. You should only take these if instructed by your doctor. Some antacids can make it harder for your body to absorb Crestor.
Crestor should not be taken if you are pregnant, as it may cause birth defects. You should stop taking Crestor and consult your physician immediately if you become pregnant while taking Crestor.
