What is Dupixent?
Dupixent is an injectable drug that is used to treat a range of inflammation-related ailments. Dupixent is a drug that blocks the inflammation response by connecting to an inflammatory protein referred to as the interleukin-4 (IL-4) receptor alpha subunit (IL-4Ra), which causes inflammation.
Dupixent is used by adults and children ages 6 months or older to treat moderate to severe eczema that is moderate to severe (atopic skin eczema). It is prescribed to those suffering from eczema that is not controlled well with prescription treatments applied to the surface (topical) or who are unable to use topical treatments. Dupixent can be administered alongside or without the use of topical corticosteroids. Dupixent is prescribed to children and adults aged 6 years or older for treating moderate to severe asthma in adults and children who are at least 6 years old. It is combined with other asthma medications to maintain the treatment of patients with asthma that isn't managed by their current medications. Dupixent is prescribed only to the adult population to address a problem referred to as chronic rhinosinusitis (long-term sinus inflammation), which is caused by nasal polyps. Dupixent is a treatment for eosinophilic esophagitis for children and adults who are 12 years old or older and weigh at least 88.5 pounds (40 kg). Dupixent can also be utilized to treat adult sufferers of prurigo nodularis.
