Dupixent

I just posted but I need help again. I finally started using light steroids a year ago after 10 years of on and off horrible eczema. For some reason I’m tending to flare during the end of July to August and my steroids aren’t helping at all. I am absolutely TERRIFIED of developing TSW and I have read up on it. For those who have taken dupixent, is there a risk of developing some type of withdrawal symptoms or tolerance? I just need relief and I will start dupixent if I can’t fix this another way.
