Saturday morning hugs for you and for Max. I can offer you no additional information as I am completely unfamiliar with this drug.

I recall when my Magic was so ill that I read and read and ended up with a whirling mind full of bits of information, but no clear direction came to me.

It was at that point I made the decision to take Magic off all chemo treatments and stop torturing him with visits (overnight) to the vet. I feel that he had a good quality of life until the day came and he clearly told me it was time.

It broke my heart, so I understand what you are doing and how you feel.
All of us do, so I will add my name to the list of people who love you and
want to comfort you as much as we can.
