Hmm, what about adding something from the mesalamine family (like Asacol, Lialda, Pentasa, etc) before changing the remicade dosage? Also, I think you can play around with the frequency of remicade first before adjusting the dosage. For example, my husband is currently on remicade every 6 weeks instead of every 8 weeks. I've also heard of people going to remicade every 4 weeks. I'd try that before upping the dosage to 10mg/kilo.
Discuss those options with your doc, and see if insurance will let you change the frequency of the infusion.
Hope things stabilize soon!
