Common side effects of Dupixent (dupilumab) can include injection site reactions, which may appear as redness, swelling, or itching where you received the shot. Some people may also develop cold sores while using this medication.

More serious but less common side effects can include eosinophilia (increased white blood cells), which might cause symptoms like coughing, difficulty breathing, rash, or fever. Some people may experience burning, numbness, or tingling in their hands. It's worth noting that some MyEczemaTeam members report having no side effects at all with Dupixent. However, if you're questioning its effectiveness after a year of use, it's important to discuss these concerns with your healthcare provider. They can evaluate your response to the medication and determine if adjustments to your treatment plan are needed.

If you experience any severe symptoms like facial swelling, trouble breathing, dizziness, or severe joint pain, seek immediate medical attention as these could indicate an allergic reaction.
