How many dupixent injections are given per month?

How many Dupixent injections are given per month?

Most adults and adolescents with atopic dermatitis or asthma receive one 300 mg injection every two weeks, which equals two injections per month.

For eosinophilic esophagitis, the same every-two-weeks schedule applies.

Children aged 6–11 with atopic dermatitis receive weight-based dosing that may be one 200 mg or 300 mg injection every four weeks, resulting in one injection per month.

In chronic rhinosinusitis with nasal polyps, the standard schedule remains one 300 mg injection every two weeks.

When is the dose changed to monthly?

For some younger children or patients whose condition is well controlled after initial every-two-weeks treatment, doctors may extend the interval to one injection every four weeks.

Why do dosing schedules differ?

The frequency depends on the approved indication, patient age, weight, and response to therapy. Asthma and atopic dermatitis labels allow the every-two-weeks regimen for most patients, while certain pediatric protocols use monthly dosing to reduce injection burden.

Can patients self-administer at home?

Yes. After proper training, patients can give the pre-filled syringe or pen at home on the same schedule, which keeps the monthly count consistent with the prescribed interval.

How does this compare with other biologics?

Unlike some therapies that require weekly dosing, Dupixent’s every-two-weeks or monthly schedule is relatively convenient. This difference can affect adherence and total injections needed over a year.

When does the patent expire?

Dupixent’s composition-of-matter patent in the US is expected to expire in 2031, with possible extensions. After expiry, biosimilar competition could affect pricing and availability.
