Tell your doctor about all of the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
Especially tell your healthcare provider if you are taking oral, topical, or inhaled corticosteroid medicines or use an asthma medicine. Do not change or stop other medicines, including corticosteroid medicine or other asthma medicine, without talking to your healthcare provider. This may cause other symptoms that were controlled by those medicines to come back.
DUPIXENT was studied in the VENTURE trial, where 86% of patients reduced or eliminated their oral steroid dose with DUPIXENT 300 mg + Standard of Care (SOC) vs 68% with placebo + SOC.
Do not stop taking your corticosteroid medicines unless instructed by your healthcare provider. This may cause other symptoms that were controlled by the corticosteroid medicine to come back.
The most common side effects include injection site reactions, high count of a certain white blood cell (eosinophilia), and pain in the throat (oropharyngeal pain).
