Around the same time I started taking Simvastatin, My period stopped happening, before this I was regular. I am only 35 years old.
There is potential for statin medications to change menstrual period duration and cause increased bleeding. I recommend discussing with your physician.
All the best,

I was looking for information on this same topic. I have been keeping track of my cycles so that I could tell my doctor if they were changing due to becoming premenopausal (even at 42). So I know that I have a dependable 25-26 day cycle.
I started simvastatin in late July/early August. This first month my cycle increased to 27 days; not a big deal at all and it latest a bit longer than usual. But this month, I'm already on day 33 and nothing. Took a pregnancy test to rule out the very slim chance that I could be pregnant (I'm not).
I don't know the answer to your question, but I wanted to let you know that you are not alone. I wish that I could have found any other references to whether simvastatin altered menstruation regularity. But I didn't.
So have things gone back to normal for you? Or are your cycles still messed up? I'd kinda like to know what your experience has been.
