A while back, I developed an itchy rash. My only relief was a certain steroid. I tried all treatments. Meanwhile, I also suffered from chronic asthma and was using Zolair, which was given at the doctor's office. My dermatologist suggested using Dupixent and since I had a grant for the Xolair, I was very hesitant. In the end, I did switch and all I could say was WOW! Not only did the rash clear up but the Dupixent gave me asthma relief like the Zolair did but I do the injections myself instead of driving all the way to the doctor. Initially the Vanderbilt Pharmacy handled this for me. Recently, I changed the prescribing doctor to my pulmonologist. It took some doing and lots of calls but I had a grant for it before and still do, even though I changed prescribing doctors. I still have some breathing issues but they are very minor compared to the way it was before Dupixent. I also use inhalers although my need for rescue inhalers is minimal now. My insurance pays all but $80 a month and with the grant I pay nothing.
