I believe crestor has a half life of around 18-19 hours. So, it doesn't take long to be removed from the body. Wasn't crestor the statin that had a petition raised against it and sent to the FDA, who threw the petition out? I agree with the FDA, there was no real basis to have the drug removed.
I would need to know what side effects and how long you were on the drugs. Typically, the normal muscle pains will be gone in a day or two. The more severe side effects can last longer. Are you sure the side effects were from the statin as the listed side effects are very common to many conditions. In studies, just as many on the placebo control group reported side effects as the statin control group, about 1 in 2,221.
Let us know.
