Is that 1 apriso at 375mgs each? A dose of 1,500 mgs a day (or 4 pills) a day is more typical for those on Apriso.
Yes, remicade/infliximab is weight dosed, I'm on it and they weigh me each time.
It's true that humira/adalimumab is not dosed on patient weight, rather everyone gets the same initial fixed dose. It is later adjusted based on patient response. I found a few scientific journal articles stating it was less effective in patients with a higher bmi, and perhaps it should be weight-dosed.
Personally, i'd trust a gastroenterologist's opinion more than a primary care doctors...
