Will Dupixent Cost More Due to Tariffs?
Dupixent (dupilumab) is manufactured by Sanofi and is classified as a dermatology medication. Sanofi is one of the 13 Annex III companies that signed MFN pricing and onshoring agreements with the US government. As a result, Dupixent carries a 0% tariff rate under the Section 232 pharmaceutical proclamation, effective July 31, 2026.
Remember that the tariff applies to the drug's acquisition cost — the price pharmacies pay to purchase the drug — not necessarily your final copay. Patients with insurance may see the tariff impact appear gradually through formulary changes or premium increases. Uninsured patients and those paying cash prices may see more direct impacts.
