propranolol and menstrual cycle

Posted , 11 users are following.

I was on propranolol for over a year. After being on it for 2 mths at a high dose 120mg- I felt like something was changing. I went off the birth control pill- and low & behold- my period stopped! Completely- no slow taper- nothing! I was thrown quickly into a menopausal state and felt crazy! I am only 45 yrs- so STRANGE! I had also gained an unusual amount of weight throughout my middle- over 20 lbs!

I few other things happened- and I decided to ween myself off it. (You MUST do this or you will have withdrawal symptoms! !) When I got down to 10mg- my periods came back!! So weird! Definitely link I feel! ! I have weaned myself off completely. I feel doctors aren't forthcoming or do not know enough about all the side effects from this drug!

Think twice before going on...try low dosage first at the very least!

Anyone else stop their monthly cycles on this medicine? ?

    Hi I'm 43 and have been on propanolol 80mg for 9yrs. I have just recently decided to come off them, I'm just coming of 50 to 40mg and I have just had an early period and I can time mine nearly to the second. I have never had an irregular period in my life so I think that there definitely related. I just hope it goes back to normal when I'm finished.

    I was already prescribed toparimate, but since it hasn’t really helped (after school ended for the summer it worked good for like three days and returned to not working for mostly the time) I have been taking toparimate for 12 weeks.

    my my neurologist just prescribed propranolol for migraines, and I also had a high blood pressure (140/80) the dose is 20 mg two times a day. I haven’t taken it nor physically have the pills yet. Topiarmate is making me lose weight and I’d rather this not counter that. I need to lose weight. 

    Maybe be this will stop my period? Toparimate made my periods very early and last time it made it irregular (2 times a month then spotting popped up 3 days later) so I am going on birth control or thinking about it if it doesnt chill. 

    Im 17, so these migraines aren’t helpful to trying to do anything in the summer and nor school.

    I realise this original discussion is quite old but I have been taking Propranolol for around 2 months (40mg twice daily for migraine) or so and having read other discussions, I believe it could be responsible for my periods changing. I am 44 and my cycle is pretty regular. I was 11 days late for my last period, which I’ve never been before, and I’ve just started another period two weeks later. Whilst Propranolol doesn’t state this as a side effect, I think there is not enough data to confirm one way or the other. The only trial I can find on propranolol and periods is in a short study with 9 woman , which looked at the affect the cycle had on propranolol, not the other way around. There was no significant difference found but there might have been numerically and this study is far too small and short to draw any conclusions in my opinion. The study only followed one cycle as far as I can see up to 16 days so doesn’t look at the long term effects the drug could have on periods.  When a drug is new to market, all adverse events are supposed to be reported but maybe when the drug was new, the population being prescribed was older and didn’t have periods anyway

    . I would be interested to know since it got an indication for migraines for a younger population what the reports have been, although I don’t think an established drug would have to report adverse events for a new indication. My view is that additional research should be done on this to warn women, esp younger woman of this potential side effect. A common side effect is 1 in 10 people suffer so if there’s not even 10 in the study to start with, hardly tells the full picture. Thanks for reading.

      Hey Sarah, I’m 16 and have been using propranolol for chronic headaches. I got my first period since starting this medication and my blood has been brown the whole time and it has been a whole week since my period should have ended, but I am still experiencing “bleeding”.  Despite this unfortunate side effect, I still continue to take it as the alternative is substantially worse.

      just checking to see how your periods have been since the one you posted about. I started taking Propanolol about 6 weeks ago and I had an odd period right away but this month is late and just small amounts of brown off and on. Ive never experienced this before so I can only blame the medication since its the only thing that had changed in my life. just curious how youre doing!

      Hi, ive been taking propanolol for about 6 months now and in the first 3/4 months that was the same for me, i had really irregular periods and then they stopped and it was just brown on and off not like a period just multiple times during the month it was the brown. But id say the last month or 2 ive had nothing what so ever and i was starting to worry but reading this it seems it could just b a side effect

      hi April. just been reading. the posts. as I've been on propranolol. for only few weeks first 2 weeks. i spotted. brown. and tiny bit blood with one weeks rest then again today bleeding again ! thats 3 times in 4 weeks . I'm on a mini pill so don't have a period ever until started taking propranolol these last few weeks . But my main concern is that. its cancelled out the effects of my pill and it is no longer working. ? But as stated in other post. there is no information on this anywhere and for younger girls on the pill. and taking this. this would be very important information for them. I'm pretty sure they don't want to be falling pregnant due to their pill not working and down to poor information. i know i don't . I'm 42. my mum. said. probably the change. and i had started to think maybe it was. until reading these posts I'm now convinced. its definitely linked. to the the propranolol thanks for reading .

    Hi I have been taking propanalol for 4 months for anxiety, I was prescribed anything up to 120mg per day, I was advised to keep my dose low so as it seemed to lnock the edge off at 20mg a day I have stuck to that dose except on days my stress levels were high! I didnt notice any change in my cycle at all but there were other symptoms! Over the last few weeks I have been under a lot of stress and so have been taking 40mg regularly in this short few weeks I've had cramping, sharp stabbing pain not to the side as with a normal period but centre! This was then followed by a very heavy bleed, I am on the coil and dont normally bleed, only tiny spotting, this was the second period in 3 weeks which is also not normal for me.

    Im currently waiting for tests but as I have a lot of other side effects I am weaning off them! No idea how this will affect my anxiety but the side affects are not worth it!!

    Also just to add when the heavy bleeding stopped I was also bleeding brown dryish blood! I am going to report all of my symptoms as there are loads including massive weight gain, I would encourage you all to do the same .
