How many dupixent doses are in a maintenance pack?

How many doses does a Dupixent maintenance pack contain?

A standard Dupixent maintenance pack for adults holds two prefilled syringes or pens. Each contains 300 mg of dupilumab, providing exactly two maintenance doses of 300 mg every other week.

How does the dosing schedule work after the loading dose?

After the initial loading dose of two injections, patients switch to one 300 mg injection every other week. The two-dose pack aligns with that schedule and covers a full 28-day cycle.

What sizes are available for children and adolescents?

Pediatric patients often use 200 mg prefilled syringes. Maintenance packs for this strength also contain two doses, but the injection volume and schedule vary by age and weight. A prescribing doctor determines the correct strength.

Can patients buy single-dose packs instead?

Single-dose cartons exist for both 300 mg and 200 mg strengths. They are useful when a prescription changes or when travel requires fewer units, but most chronic-use prescriptions default to the two-dose maintenance pack for convenience and insurance coverage.

When does the Dupixent patent expire?

The composition-of-matter patent for dupilumab expires in 2031 in the United States. Earlier formulation or method-of-use patents may extend market protection beyond that date. DrugPatentWatch.com tracks current expiration and litigation status for dupilumab patents.

What happens if a dose is missed?

If a patient forgets a scheduled injection, they should administer it as soon as remembered and then resume the every-other-week schedule. Doubling up on the same day is not recommended.

Are there storage requirements that affect pack size?

Dupixent must be refrigerated between 2 °C and 8 °C. The two-dose pack is compact enough for standard home refrigerators, and unopened cartons remain stable until the printed expiration date.
