Hi Worried,


There is potential for statin medications to change menstrual period duration and cause increased bleeding. I recommend discussing with your physician.


All the best,

women are at higher risk for statin adverse effects and several studies question the usefulness of statins for women at all. you should read and understand the following:

Hi worried,


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.
