How long does it take for Simvastatin to get out of your system once you stop taking it?

I'm 65 years old and been on simvastatin for over 30 years. I never had any side effects until a few years ago. I might note I was diagnosed as bi-polar at 40 and have been on many medications since. The only constant has been the simvastatin. A few years ago I started with some tremors in my hands and feet which progressed to a point that I couldn't even write. Two weeks ago I saw a neurologist and his first action was to take me off the simvastatin. Now 14 days later most of the tremors are almost gone and my cognitive skills have improved in a way I would never believed possible. I'm supposed to take a new drug tricor but I'm a bit shy about it.

I started Simvastatin 3 days ago and I looked up the side effects and one of them was insomnia and they mess with diabetes. I an a type 1 diabetic an it has my sugars so outrageous and I can't sleep and I've been sick since I started taking them.

I started simvastatin 2 months ago and within 24 hours started getting sick when I ate and woke up everyday with a headache. I now may have type 2 diabetes. My doctor ordered blood work. I quit taking the simvastatin two days ago and my blood sugar levels are coming down. They were 244, 2 hours after eating. Now they are around 134. After all night fasting they were 117 the second day after stopping the medication. What's going on?

There are other meds for cholesterol then statins too, if you find you're intolerant to them.

14 days for meds to clear as I was told . There are 5 other statins to choice from you need be be on one if you already had a stroke . As for weight gain and anxiety I could say.

Hi, Jo-anne! I'm very sorry you had such a terrible time. Simvastin is a short-acting medication with a half-life of about 12hrs. That means if you took 40mg at 12:00pm, at 12:00am there would be 20mgs in your body, at 12:00 noon only 10mgs, etc.
Is there any possibility that you had/have a concurrent condition that might account for the anxiety and depression? I'm not sure about anxiety, but depression has only extremely been reported with simvastatin.
Best wishes, WCV
