loss of menstruation on meds

[cutelildeadbear]

Hey Everyone,

I know this has been addressed somewhere on here but I have been doing a search for 30 minutes and I cannot find the thread anywhere. My periods have become really irregular since increasing my Topamax to 100mgs and my Lamictal to 200mgs. I'm actually supposed to continue to titrate my Topamax up to 200mgs (but I might discuss this with pdoc next week at my appointment as I feel like I'm doing really well where I'm at now). I have absolutely no other side effects. I don't even have the flat soda taste or the tingling or the "dopey" forgetting from the Topamax. I've been on the Lamictal at 200mgs for longer than the Topa, which is why I suspected the Topa, since I just started increasing the Topa the past two months (25 mgs every 2 weeks- we wanted to do it slowly after a long time on 25mgs with no results there).

 

Prior to the change in meds I have always had a very regular periods so this is weird for me. Also, I have all of the symptoms and signs that I'm going to have my period, but it just doesn't come. Headaches, breast tenderness, slight cramps, but then nothing. I know that I'm not pregnant because I haven't had sex in months and recently had a pregnancy test at the ob/gyn for my annual checkup which was obviously negative.

 

So, I'm just curious if anyone else has experienced this or if it is a known side effect of either Topamax or Lamictal. I had not experienced this side effect until I got up to 100mgs. I have been researching the internet but I can't really find this as a "side effect" just some conflicting experiences from people who are on the drugs for different reasons.

 

Thanks in advance for any advice!

i've never tried topomax but i've been on lamictal for a long time.  that med in particular hasn't caused any hormonal weirdness for me.  i have been on other meds that completely screw up my cycles in both frequency and quality, though.  since everyone is different that way, i'd check it out with your doctor just in case it's somethng else.  also i'm not sure how old you are, but premenopause can do this (and can happen years and years before menopause, so i've recently learned).
