Hi, I was happily on Simvastatin for years, then my GP changed me to Atorvastatin because a blood test showed that my cholesterol was high. A few weeks after starting the Atorvastatin I developed horrible anxiety, bad dreams and my husband says I spend all night jumping around and twitching (no wonder I wake up exhausted!). I've also been suffering from excessive sweating first thing in the morning. Atorvastatin does list depression, nervousness and bad dreams as being extremely rare side effects. I'm also aware that mental health issues, for all sorts of reasons, are extremely common and I don't want to come off my statins unnecessarily. Has anyone else suffered anxiety/depression etc as a result of Atorvastatin and, if so what should I do? Should I half my dose from 20mg to 10mg to see what happens. Would be really grateful for some advice/reassurance if anyone can offer any. Thanks.
