Good morning, I am 9 days post taxotere/cytoxan, treatment #3. I woke up Friday 4 a.m. with hives over my body, from head to knees. I decided to go to the ER in fear of progression. I was afebrile, may ANC was 320. When discharged from the ER I was given prednisone, diphenhydramine and zantac. Assuming this is an allergy driven event, I would like to know when my immune system stabalizes, does the allergy go away? ;) Thank you ahead of time. :)
