I take Simvastatin (Zocor) too. My cholesterol level is fine. I’m on resperidone and cogentin and webutrin. I have no side-effects from Zocor that I am aware of. Medicare or Medicaid covers the cost of all my medications. I have been on Zocor for at least 5 years, at one point a few years ago my cholesterol was so under control that my doc took me of it! But I eventually got back on it. One weird thing about Zocor and a few other medications is that you can not eat any grapefruit or grapefruit products while on it. I should mention here that diet plays a part in high cholesterol.While I was on Atkins my bad cholesterol went DOWN and my good cholesterol went up. Despite it being a high protein diet involving eating lots of meat. But I really think this is a discussion that you should also have with your GP or even your psychiatrist since they’re medical doctors too.
