Can dupixent help with nasal polyps?

Can dupixent reduce the size of nasal polyps?

Dupixent (dupilumab) is approved to treat chronic rhinosinusitis with nasal polyps in adults. It works by blocking interleukin-4 and interleukin-13 signaling, which lowers inflammation and often shrinks polyp tissue. [1]

How long does it take to notice improvement?

Most patients see polyp reduction and fewer sinus symptoms within four to sixteen weeks. Symptom scores, nasal blockage, and sense of smell continue to improve for up to one year in studies. [1]

What dose is used for nasal polyps?

The standard regimen is 300 mg injected under the skin every two weeks. Some patients start with a loading dose of 600 mg, but ongoing treatment stays at 300 mg bi-weekly. [1]

Can dupixent replace surgery for nasal polyps?

It is not a direct substitute for surgery. In people with severe or recurrent polyps, dupixent can delay or reduce the need for repeat operations, but surgery may still be required if polyps cause major blockage. [1]

What side effects matter most to patients?

Common reactions include injection-site pain, conjunctivitis, and joint pain. Serious risks such as allergic reactions or parasitic infections are rare but require monitoring. [1]

How does dupixent compare with steroids or other biologics?

Unlike oral steroids, dupixent can be used long term without typical steroid side effects. It is the only biologic currently approved specifically for nasal polyps; other agents like omalizumab or mepolizumab are mainly studied in asthma or other eosinophilic conditions. [1]

When does the dupixent patent expire?

The key U.S. composition-of-matter patent expires in 2031, with potential pediatric or other extensions stretching protection into the mid-2030s. [2]
