Sorry to hear that Abby's belly is not liking the masitinib. Rio had a little looser rear end a couple of days early on when she first started on it, but nothing that I would classify as diarrhea. She was on Pepcid, though, when we were taking the masitinib, and it's possible that helped a little with the tummy troubles.

I wouldn't give up on it right away — when she prescribed it for Rio, my onco said it could take a little bit for her tummy to get used to the new meds. Your onco can always give you metronidazole or you could try Fortiflora (that's what we give Tosca when she gets the Texas Two-step). It's a powdered enzyme that repopulates the colon and helps with diarrhea.

Good luck!!!

Thanks. After posting I found a vet site that said it can take a little getting used to. We do have some flagyl left from when she was on the Palladia. (we haven't tried the clay thing. Will have to get some of that. Whole Paycheck… That's funny….)

Ok, we will just skip it tomorrow and call Dr. V on Monday.

Hope you find a good solution soon! She's quite the trooper, though. Poopy, yet perky! Go Abby!

What is Masitinib?

Masitinib and Palladia are both at-home low-dose chemo pills.

She seems absolutely fine today, but of course, we didn't give her her pills today. She was crazy as ever and no signs of continuing tummy trouble. (Didn't even give her anything for the diarrhea, other than some pumpkin in her meals, and she seems fine.)

We'll see what her onc. says tomorrow.
