Hello Crestor is a brand name for a medication called rosuvastatin, which reduces levels of bad cholesterol and triglycerides in the blood, while increasing levels of good cholesterol. Crestor is also used to lower the risk of stroke, heart attack, and other heart complications, it s also used in certain people with risk factors like the high blood pressure that you have even if it s well controlled. In your case a total cholesterol level of 268 mg/dl is considered at a high level, which is normally shouldn t be more than 200 mg/dl. For that reason rosuvastatin is surely indicated in your case. The most common side effects of rosuvastatin may include: Liver symptoms (stomach pain, dark urine, jaundice), unusual weakness or tired feeling, headache, muscle aches, nausea, upset stomach. If you think that you have symptoms caused by Crestor call your doctor to change it or to reduce doses. The risks of Crestor are mostly for the kidney and liver, if you don t have any trouble in urinating or any swelling, If there s no sign of liver trouble you should continue your treatment because you need it. Hope I answered your question Wish you a better health Best regards Dr. Noor Farid
