+ it's a very strong drug
+ it's long lasting
+ it can inhibit MAP by killing TNF-alpha
-it's a new drug, they don't know what it does with the body, at all, the discovery that it inhibits MAP is literlly hot off the presses, they seriously have no clue why infliximab works so well
-for some people it has been linked to side effects, infliximab has killed quite a few people, but as a percentage the number is really low. But as a percentage of medical drugs the percentage is high, infliximab was responsible for the most medical related drug deaths a few years ago I believe. Many of those happen when peoople go on infliximab and they create antibodies to the drug, they get the drug and the body reacts and they die if the drug isn't removed fast enough.
-some argue that infliximab could make crohn worse in the long run because of it's action on the immune system, the theory of many is crohn is an underresponsive immune system, and infliximab could make this worse (

I'm off the drug for almost a year now, and frankly I'm relieved. Maybe it's because I read so much about it, maybe it's because I know it's not a real solution, maybe it's because I can have an ease of mind that my body isn't on such a crazy strong drug anymore, but I'm happier now.
