Dupixent is not a cure for eczema; however, it does effectively reduce symptoms in the majority of people prescribed it. Dupixent significantly reduces itching, skin appearance, the frequency of AD flares, sleep, and quality of life in most people. However, there does appear to be a subset of people who only partially respond to Dupixent (partial responders), or who respond initially, and then their symptoms return (non-durable responders).
