What is the best time of day to take Crestor?
Doctors recommend that you take statin drugs (like Crestor, aka rosuvastatin) at night, before bed. This is suggested because you make more cholesterol in your liver at night when fasting than during the day when eating. Statins inhibit the formation of cholesterol, so taking the medication at night when more cholesterol is made, maximizes the efficacy of the medication.
Of course, there are other things you can do to help lower your cholesterol, and I hope you're taking advantage of those things as well. Here are a few articles that may be useful to you:
