Hi Everyone, I pray you are all coming along well. My post is regarding my allergic reaction that I experienced this past week. I started on my maintenance regiment on Wednesday, which consists of Dexamethasone, Lenalidomide and Faspro. Two hours after my treatment, I started itching, broke out in hives, shortness of breath, nose and throat began to close. Rushed to the ER, where they administered an antihistamine, Benadryl and another medication, can't remember. Symptoms subsided, thank God and I was able to return home. Question: Has anyone ever experienced this situation when starting their maintenance treatment. What could it have been? I had taken these medications prior to the transplant with no reaction. Could it have been my new immune system? I don't know and neither does my doctor seem to know. Any help would be appreciated.
