Hospitalization for diarrhea associated with perjeta?

Fcmom2

I have been in the hospital for a week due to severe diarrhea that will not stop -8-15 times per day! It started 48'hours after my second chemo treatment. I had D for 2.5 weeks after my first chemo of HPTC but lomotil seemed to work ok so that I could continue to work and take care of kids. Onc thinks it's the perjeta. Anyone else have this issue or know for how long I will be here?? They tried taking me off steroids and IV anti diarrheal meds so I could try to go home from hospital and my body crashed and got much worse so we still cannot get it under control. Definitely some nausea as well but controlled with zofran as long as I'm on the steroid. Don't know if I will be able to continue with the perjeta and just trying to get out of hospital at this point!
