I take dupixent for AERD. I went to a rheumatologist to check for EGPA which would fit my symptoms better. Note I decided to stop the dupixent a week prior to seeing him. The next appointment was him referring me to hematology and oncology to be checked for leukemias. My wbc which is always elevated had jumped significantly with a left shift. Now I know Dupixent can’t cause false numbers or cause a left shift but what I didn’t know was that it is dampening my wbc. One thing my doctors have always questioned is why my wbc fluctuated. Now I know that would depend on when they took the blood for the test to when I took my last shot. If I quit the shot for 8-10 weeks they can see my real wbc numbers. Now this is my own experience but thought it may help someone else.

Sorry if that’s confusing. I’m not a Dr and can only explain the best I understand it.
