Herceptin & diarrhea

It can be surprising how the body reacts, totally the opposite to what you would expect!  Sounds like your body is coping well and I wish you wellness as you get through the routine of counting them down!  It's a bit like the old song, there was 10 green bottles hanging on the wall!

I am prone to IBS and am on my third sub cut injection for herceptin.  So far I have had no diarrhoea.  On my fourth injection (I need 17) I will have a better idea of what herceptin's side effects are as I have finished chemo now so it will just be herceptin on its own.  I do take two multiflora tablets a day, am. and pm., and Iberogast, 20 drops in the morning for gut health ... given what chemo does to your gastrointestinal lining.  With chemo and herceptin my issue has mostly been constipation.  Odd, as if anyone was going to get diarrhoea I would have picked me!

Diarrhea is at the top of the list - hope that helps but certainly speak with your Breast care nurse and Oncology

Thanks @Payne, I will try the probiotics or some yogurt that might help to start the day off on a good note. I will have a chat to oncology next time I see them, I didn't have the chemo because I had an instant reaction to paclitaxel, so it's diffinately something to do with the Herceptin, I did also have a few tomato based foods yesterday but I'm good one day then just bad another.

Im a little concerned as I hope to go back to work in the New Year. 

I don't know of specific foods but if this is a new thing for you, is probably the herceptin. Maybe your gut might need some probiotics.  There is medication you can take but unless you are getting dehydrated or is hugely inconvenient, eg, working, the conservative approach might be better for you.  I didn't get diarrhoea from herceptin  but I did with the chemo but not every day and fluctuated between that and constipation. Can you phone your chemo nurse?
