terrible nausea


Re: terrible nausea

I have found taking half tablet morning and evening lessons side effects.


Breast care nurse helpline sugested doing this.


Nausea seems to be affected by any stress, emotions, etc, comes in waves.


So stress may be making this side effect worse maybe?

Re: terrible nausea

Hi Pollyanna I had my third session of Radiotherapy today and felt nauseous this afternoon but like you I started taaking letrozole about 3 wks ago so I guess it could be that but I have a hunch it was the rads causing mine not the tablet as it takes about 6 wks to get into your system apparently. hope the nausea lessens son whatever the cause Take care hugs from Corrina xx

Re: terrible nausea


I agree with the others in that its probably the letrozole. I take mine in the evening and then don't have any problems x

Re: terrible nausea

Hiyer, Its really hard when symptoms like this appear isn't it, during active treatment....as its hard to work out what could cause it with so much going on. It could be the hormone med, BUTU...ages ago I recall another thread where some people said they had nausea during rt. I seem to recall that they were advised to increase their fluid intake?! I've just done a quick forum seach for 'radiotherapy and nausea' and lots of posts come up, but I can't find the exact one I can remember.

Re: terrible nausea

Hi pollyana

I take my Anastrozole just before bed on the principle that if it makes me feel nauseous i won't be awake to experience it, and so far so good. I don't think it matters when we take our tab so long as it is broadly at the same time each day, so do what works for you. Hope the situation improves.


Re: terrible nausea

thank you so much.

i also take my tablet at about 9 am so will perhaps try taking it with my evening meal instead.

will mention the nausea to the radio. staff on monday.

many thanks

Re: terrible nausea



Hi and welcome.  I am not sure if radiotherapy would give you nausia, it might be the letrozole.  What time do you take your tablet, it might be worth trying to take it at a different time and perhaps having it after food.  I am on tamoxifen and I take mine at 9am in the morning after I have had my breakfast.  I know on here where ladies have had problems with their hormone tablets they have tried changing the time they take it at.  Also it might be down to the particular brand as again I have heard ladies saying about the change of brand can give them side effects as well.


It would be worth mentioning it to your rads team on Monday and see what they suggest.
