 Stay ahead of your moderate to severe eczema and show off clearer skin and less itch with Dupixent, the number one prescribed biologic by dermatologists and allergists that helps heal your skin from within. Serious allergic reactions can occur that can be severe. Tell your doctor about new or worsening eye problems such as eye pain or vision changes, including blurred vision, joint aches and pain, or a parasitic infection. Don't change or stop asthma medicines without talking to your doctor. Ask your eczema specialist about Dupixent.
