I've only been on Promacta since November 19, and my body is still reeling from the almost 18 years on prednisone and its taper, so it's hard for me to know what symptoms are caused by what. I note that one of common side-effects for ITP treatment is stuffy nose and/or upper respiratory infections. I have allergies anyway, but an air purifier has helped with those. I can barely breathe, though, out of my nose since I began taking Promacta. Have others had this problem? Is it likely to continue, or will my body become adjusted to the drug and the problem decrease? A squirt of Afrin helps, but one shouldn't take that regularly. Any suggestions?
