I have rheumatologist just concern if he is actuate with me or maybe I should get a second opinion. Tried serveral different meds now on Remicade, started out every 8 weeks with 300 mg didn't last 8 weeks, used prednison till second 8 weeks went up to 600 mg didn't last either, not sure how long it did last, but went to every 6 week 300 mg only lasted 4 weeks exactly used predisone to make it 6 weeks went up to 600 mg only lasted 4 weeks again used predison to last to my 6 week treatment & he is saying he would go up to 900 mg this time I am thinking it didn't last any longer with 600 mg than it did with 300 mg would you go up to 900 mg or why not just start treatment at every 4 weeks instead. He says that the Remicade isn't working but it does work for 4 weeks. Bill
