Oh weird to see an old thread like this! Looks like I've been on perjeta for a year now. It was definitely the Gemzar causing my nausea. I've never had any bowel issues. The only thing Perjeta has done for me is made me completely stable! No new cancer, no growth and I've been off chemo and only on perjeta for six months.
I LOVE PERJETA!!!!!!
I think if your mother is having pure liquid diarrhea it is imperative she go in for a stool test. (She can do it at home but she should see her doctor) She may have something more insidious, like c-diff, which can be deadly. That doesn't sound like a normal side effect of perjeta to me, having liquid diarrhea. I wouldn't wait, if she has an infectious disease like c-diff, the longer she goes without treatment, the more dangerous it could be. I went septic from it.
Has she been on antibiotics or been in the hospital recently? That would give a clue that the possibility that c-diff is a real one. If she does take immodium, it could make it much worse as the toxins won't clear her GI tract. Not to scare you but I was sicker from c-diff than I ever have been from cancer and as you can see, I have had a lot of treatment. C Diff was the worst thing I"ve ever experienced and that's saying something.
Good luck to your mom. I hope you get it figured out soon. Definitely call a doctor.
