Fasenra was a nightmare for me. After the first injection I felt fine and my asthma symptoms seemed to improve, however the second injection was different. It lowered my immune system, turned my tongue white and I had flu like symptoms for months. Plus my skin color had a pink hue. Please be careful!

While I haven't had fasenra dupixent worked wonders for me and its helping me get into a normal range of breathing for the first time in my life, best of wishes to you <33

I know this is an old post, but fasenra worked great for my eosinophilic asthma. I didn't notice any side effects, and I didn't need to use oral prednisone anymore at all. If it becomes available to me again, I will definitely get back on it.
