Which companies supply acetylcysteine injection in the U.S.?
Acetylcysteine injection is an established generic medicine, and multiple manufacturers may supply it depending on the dosage strength and package size. Supplier availability can change due to manufacturing schedules, regulatory actions, and demand.
How to find the current suppliers for a specific acetylcysteine injection strength and NDC
To identify the right supplier list, use the exact product identifiers:
- NDC (National Drug Code)
- Strength (for example, mg/mL) and vial/bottle size
- Formulation (e.g., “acetylcysteine injection,” sterile, for IV use)
With the exact NDC, you can check which labeled manufacturers are supplying that particular version of the injection.
Where to check manufacturer and supplier details (NDC-level)
The most practical way to verify current manufacturers is to search by NDC in drug listing databases (often used by pharmacies and wholesalers) and cross-check the product label’s “manufactured for” / “distributed by” details.

If you’re a hospital/wholesaler: what to ask about when sourcing
When comparing suppliers, request product-specific documentation for the exact NDC you’re buying, including:
- Current labeler/manufacturer name
- Expiration date and lot numbers
- Storage requirements (temperature and handling instructions)
- Packaging format (vial vs bottle, unit count)
- Supply lead times and allocation policies (if any)
Tell me the exact product so I can narrow to likely suppliers
If you share any of the following, I can help pinpoint the likely supplier/manufacturer set for that exact product:
- NDC number (best)
- Strength and container size
- Country/state (if not U.S.)
- Brand vs generic (if known)
