Who Supplies the Pharmaceutical Product “Epinephrine (Autoinjector)”?
Which companies supply epinephrine autoinjectors to the US market?
Epinephrine autoinjectors are supplied by multiple branded-product manufacturers, with the active drug (epinephrine) and the device integrated at the product level.
| Branded autoinjector manufacturers (US, by product label) |
Product (brand) |
Manufacturer on US label |
Product type |
Notes on supply footprint |
| EpiPen / EpiPen Jr |
Mylan Pharmaceuticals Inc. (now part of Viatris) |
Needle-based autoinjector |
Historically one of the dominant suppliers; product remains labeled to Mylan on many US labels. |
| Adrenaclick |
Kaléo, Inc. |
Spring-driven autoinjector |
Distinct device platform; supply depends on Kaléo manufacturing and distribution. |
| Auvi-Q |
Structure Therapeutics, Inc. / Xeris Pharmaceuticals, LLC on labeling (varies by label revision) |
Needle-based autoinjector with voice guidance |
Labeling ownership changes by product lifecycle and corporate actions. |
| Symjepi |
Amneal Pharmaceuticals LLC |
Needle-based autoinjector |
Market supply tied to Amneal’s product lifecycle and distribution. |
| Generic epinephrine autoinjectors |
Generic NDA holders and contract manufacturers vary by product |
Same class of device-integrated drug |
Supply depends on which generic product is active, with labeling naming the marketing authorization holder. |
Which suppliers actually manufacture the device system and drug product?
Autoinjectors are typically manufactured by a combination of:
- Device manufacturing (spring/needle mechanism, housing, electronics if present, and assembly)
- Drug-product filling and packaging (sterile epinephrine drug product filled into the device-compatible reservoir)
- Final assembly and kit packaging (carton, instructions, needle safety features, and labeling)
In practice, the market supplier is the marketing authorization holder listed on the FDA label, while manufacturing may include contract manufacturing for one or more process steps. FDA labeling for each product provides the definitive “who supplies the product” at the branded/generic label level.
What do FDA labels show about supply entities?
FDA product labels identify the manufacturer/holder responsible for the marketed product for each presentation. That label-level entity is the actionable supplier contact for procurement, distributor onboarding, and pharmacovigilance routing.

Procurement implication |
| EpiPen / EpiPen Jr |
Manufacturer listed as Mylan Pharmaceuticals Inc. |
Supplier procurement routes through Viatris group label entities for those SKUs. |
| Adrenaclick |
Manufacturer listed as Kaléo, Inc. |
Procurement routes through Kaléo label entity for SKU-level availability. |
| Auvi-Q |
Manufacturer/holder listed as Structure Therapeutics/Xeris depending on label revision |
Procurement requires SKU-specific label verification. |
| Symjepi |
Manufacturer listed as Amneal Pharmaceuticals LLC |
Procurement routes through Amneal for those SKUs. |
| Generics |
Manufacturer/holder varies by NDA holder |
Procurement requires product-specific verification. |
Who are the key branded suppliers in the autoinjector category?
Across the category, the supplier set that matters for market access is the set of brand label holders below.
Primary branded category suppliers
- Mylan Pharmaceuticals Inc. (EpiPen / EpiPen Jr)
- Kaléo, Inc. (Adrenaclick)
- Xeris Pharmaceuticals, LLC / Structure Therapeutics, Inc. (Auvi-Q; label ownership depends on current labeling revision)
- Amneal Pharmaceuticals LLC (Symjepi)
Which regulatory source maps suppliers to specific products?
FDA’s product labeling and drug databases are the controlling sources for identifying the supplier entity named on the market label. The product’s label is the operational source used for:
- procurement target (who the product is sold under),
- adverse event reporting routing,
- and substitution decisions in formularies.
Key FDA resources used to determine the supplier
- DailyMed entries for each specific NDC and label revision (label text includes manufacturer/holder).
- FDA drug product database records for the specific autoinjector NDA/NDC entry.
How do supplier boundaries affect sourcing and substitution?
Supplier boundaries in epinephrine autoinjectors are governed by product-level labeling, not by the underlying drug molecule. Substitution decisions in tenders, hospital formularies, and pharmacy benefit design rely on:
- Device form factor (needle-based vs. alternate device platforms)
- Dose strength (0.15 mg, 0.3 mg)
- NDC-level label (manufacturer/holder entity changes by SKU and revision)
- Availability status (some SKUs shift supply during production changes)
What supplier dataset is most actionable for R&D and investment diligence?
For diligence, the operational “supplier” question is answered at SKU level using:
- the NDC,
- the DailyMed label,
- and the label-specified manufacturer/holder.
That yields a supplier list that is stable enough for contracting and governance even when corporate ownership changes.
Key Takeaways
- The actionable suppliers for “Epinephrine (Autoinjector)” are the label-identified manufacturers/holders for each specific autoinjector SKU.
- The dominant branded supplier set in the US includes Mylan (EpiPen/EpiPen Jr), Kaléo (Adrenaclick), Xeris/Structure (Auvi-Q), and Amneal (Symjepi).
- For procurement and diligence, use NDC-specific labeling (DailyMed/FDA) because manufacturer/holder can vary by SKU and label revision.
