The vet rang this afternoon. Since Herbie is developing cystitis with the cyclophosphamide (Endoxana), she's been consulting with the awfully nice people at Cambridge Vet School. Herbie's oncologist has suggested we substitute it for chlorambucil (trade name Leukeran). Again, every other day, and it's cytotoxic, so you have to wear rubber gloves to handle it. I now have a special pair of pink rubber gloves in the kitchen (Pink for Pills) just for dog medicine. Plus, this one needs to go in the fridge.
Chlorambucil has a whole different range of side-effects. Let's see how we go. Herbie doesn't know about this one yet.
