Warnings

Before starting Crestor (Rosuvastatin), you should be following a cholesterol-lowering diet. If appropriate, a program of weight control and physical exercise should also be implemented.

The recommended dose of Crestor (Rosuvastatin) ranges between 5 mg and 40 mg once daily. For most people, the usual recommended starting dose of Crestor (Rosuvastatin) is 10 mg once daily. If necessary, the dose may be increased to a maximum of 40 mg daily. People who require the maximum dose of 40 mg per day should consult a specialist.

For children 10 to 17 years of age, who have inherited cholesterol disorders, the recommended starting dose is 5 mg taken once daily. Your doctor may increase this dose to a maximum of 10 mg daily, depending on the effectiveness of the medication and how well it is tolerated.

For people with severely reduced liver function, the maximum daily dose is 20 mg.

For people with severely reduced kidney function, the starting dose should be 5 mg daily and the maximum daily dose is 10 mg.

A starting dose of 5 mg daily is recommended for people of Asian descent (Chinese, Filipino, Japanese, Korean, Vietnamese, or Asian-Indian origin) and those who have severe kidney problems.
