Nasonex 24HR Allergy is a U.S. FDA-regulated, finished-dose intranasal corticosteroid product containing mometasone furoate. Supplier identification for an FDA-marketed product is typically anchored to (1) labeling and FDA databases (Orange Book, Drugs@FDA, facility listings where available) and (2) contract manufacturing announcements, trade press, and corporate supply statements.
No sufficiently specific supplier roster (named API suppliers, labeled finished-dose contract manufacturers, and distributor-of-record sources) can be produced from the information available in this session without risking inaccuracies.
What is Nasonex 24HR Allergy and what ingredient do suppliers support?
Answer: The active ingredient is mometasone furoate in an intranasal spray intended for 24-hour dosing.
What form and route affect the supplier list?
- Dosage form: intranasal spray (nasal corticosteroid)
- Drug substance: mometasone furoate (a steroid API used for nasal delivery)
- Device components: metering valve, actuator, and dosing pump hardware (often sourced by device specialists)
What parts of the supply chain map to “suppliers”?
- API supplier(s): manufacture and release of mometasone furoate API to the finished-dose manufacturer.
- Finished-dose manufacturer (CDMO/labeler): formulation, sterile-grade handling where applicable, filling, packaging.
- Packaging/device suppliers: spray pump, actuator, container, and closure components.
Which company is the labeler of Nasonex 24HR Allergy in the U.S.?
Answer: A correct supplier map requires the specific U.S. labeler/marketing authorization holder and the product’s exact NDC strength and pack size, because the labeler and manufacturing sites can differ by presentation and over time.
Why supplier lists change by NDC
- Different strengths and package configurations can be manufactured in different plants.
- Contract manufacturing can rotate between sites while the labeler remains constant.
- API supply can include multiple vendors across time and compliance cycles.
What FDA-listed facilities support Nasonex 24HR Allergy?
Answer: FDA facility listings (where published for the relevant submission types) can identify manufacturing sites, but a supplier answer must be tied to the exact product identifier and the specific dataset entries.
Facility categories relevant to nasal sprays
- Drug substance manufacturing (mometasone furoate)
- Drug product manufacturing (formulation and fill-finish)
- Packaging/repackaging
- Clinical/RA facilities are not typically “suppliers” in the commercial sense but appear in some submissions
How do you identify Nasonex 24HR Allergy API suppliers?
Answer: API suppliers for a branded product are usually not publicly listed as a stable, single vendor. Identification is typically done via:
- FDA filings tied to the drug substance manufacturer (when surfaced in public records),
- DMF/RLD correspondence (not always public at vendor level),
- and trade disclosures from the labeler’s supply chain.
What to look for in public records
- DMF-referenced substance manufacturers linked to the NDA for mometasone furoate nasal products
- Consistency between the DMF holder and any publicly stated supplier names
Which CDMOs or contract manufacturers produce Nasonex 24HR Allergy?
Answer: Finished-dose manufacturing suppliers for branded nasal sprays are commonly contract-manufactured, with site details tied to the NDA and the product’s manufacturing plant list. A correct named list requires product-specific FDA facility data.
Typical manufacturing steps that define a “supplier”
- formulation blending of mometasone furoate suspension/excipients
- filling and spray pump assembly
- QA release testing and stability management
- secondary packaging and distribution readiness
What distributors supply Nasonex 24HR Allergy to pharmacies?
Answer: In the U.S., branded products generally move through wholesaler/distribution networks under the labeler’s distribution agreements. Named distributors change by channel and contract term, so a fixed “supplier list” is not reliable without product-specific sourcing records.
Distribution channels that affect supplier identification
- Wholesalers (national distributors)
- GPO and specialty channels (contracted purchasing)
- Direct-to-pharmacy (less common for mature branded intranasals but possible)
What supplier consolidation and dual sourcing risks apply?
Answer: For long-running intranasal brands, risk typically clusters in:
- spray device hardware availability
- container/valve glass/plastic procurement
- API batch supply continuity for mometasone furoate
Practical risk triggers for nasal corticosteroids
- valve and actuator supply constraints
- particulate control and suspension stability during formulation and fill
- regulator-driven inspection outcomes at specific fill-finish sites
Key Takeaways
- “Suppliers for Nasonex 24HR Allergy” can mean API suppliers, finished-dose manufacturing sites, packaging/device vendors, and distribution sources.
- A precise, named supplier roster requires product-specific identifiers (exact U.S. NDC presentation) and FDA-record anchoring to avoid incorrect vendor attribution.
- Supply-chain risk for intranasal corticosteroids typically concentrates in device components and fill-finish capacity as well as API continuity for mometasone furoate.
FAQs
1) Who manufactures the finished-dose Nasonex 24HR Allergy intranasal spray?
The finished-dose manufacturer is defined by the NDA product’s listed manufacturing sites for the specific NDC presentation.
2) Are there multiple API suppliers for mometasone furoate in Nasonex?
Branded steroid APIs are often sourced from multiple vendors over time, but a defensible answer depends on the NDA-linked public substance-manufacturer records.
3) What packaging and spray-pump suppliers are used for Nasonex?
These are typically device/component vendors supplying the metering valve, actuator, and container/closure system, tracked via NDA manufacturing and packaging records.
4) Can Nasonex supply be disrupted by valve or actuator shortages?
Yes, device-component constraints are a known operational risk area for metered intranasal sprays.
5) Which wholesalers distribute Nasonex to U.S. pharmacies?
Distribution is handled through established U.S. wholesaler networks under the labeler’s distribution agreements, which vary by channel and term.
