I suffered several side-effects as a result of statins. The most devasting was short-term memory loss. I was a computer programmmer and found my job increasingly difficult as a result. I had to keep making lists and checking through them as someone diagnosed with Alzeimer's might be advised to do. I lost the ability to construct a reasoned argument, since I became unable to hold all that had just been said in my memory and recall the relevant data to refute what was being suggested. My husband says my personality changed and that the person he had married had been replaced by a stranger. I knew something was wrong but nobody would listen.I believed my memory problems were due to age. At the time, I was less than 50. My GP wanted to put me on anti-depressants, but I didn't believe I was depressed, just desperate for someone to tell me what was wrong. When I was made redundant from a job I had always loved, I had difficulty marshalling my thoughts in an interview. I also lost my appetite completely. I felt empty but never hungry, so it became more difficult to get the required carbs down.
Finally, I read a letter in the Diabetes UK magazine from a university professor who had found himself unable to do his job after less than a week on statins. This sounded so like my own experience that I stopped. Some people can take statins without ill-effects, others find their lives destroyed. My husband says the woman he married was back within a fortnight. My appetite also went back to normal fairly rapidly. My memory improved over time, but very much more gradually. I would say it took years for my mind to function normally again.
If you decide to try statins, keep a log recording your health mentally and physically when you start, the drug and dose etc. Also record any change in yourself you notice. Muscle aches and pains are the only side effect doctors seem to be aware of. There are many others known. Memory problems are a known side-effect, but few of us want to admit we can't remember, which makes it particularly dangerous. If you review your log regularly, you may spot a side-effect before things get so bad as to cause lasting damage. Think carefully about this. Best wishes. Sorry for the lecture. It's because I feel very strongly about this.
