Question: I developed adult-onset asthma within the last year. My rheumatologist stopped all treatment except a low does of MTX and prednisone. Why? He told me that he has received approval for my next infusions. However, he won't give them to me until the asthma is under control. I've asked him several times and that is the only answer I've received .... he can't give me an infusion or injection until the asthma is under control. My last infusion was September 2014. By-the-way, allergy testing showed the asthma is not environmentally triggered.
