Who manufactures acetaminophen (paracetamol) in the U.S.?
Acetaminophen is made by many companies, including large branded and generic manufacturers. Major U.S. suppliers commonly produce acetaminophen under their own labels and for store brands, and it is also produced by contract manufacturers.
Because “manufacturer of acetaminophen” can refer to different products (tablets, caplets, liquid, extended-release) and different packagers/labelers, the specific manufacturer depends on the exact product and label you’re looking at.
How to identify the manufacturer of a specific acetaminophen product
Check the bottle/box for:
- “Manufactured for” or “Distributed by” (this is often the labeler)
- The “Manufacturing” company name (sometimes listed as the actual maker)
- The National Drug Code (NDC) number (best way to match to the correct product/labeler)
If you share the labeler name or the NDC from your acetaminophen package, I can help pinpoint the responsible manufacturer for that exact item.
Does the same company make every acetaminophen product?
No. Acetaminophen is widely available as a generic, and different strengths/forms (e.g., 325 mg tablets, 500 mg tablets, liquid, pediatric dosing syringes) may have different manufacturers and labelers even if the active ingredient is the same.
Patent/prescription context: is there one “manufacturer” due to patents?
Acetaminophen is an older, widely available drug and is not typically tracked like newer branded prescription medicines. Patent and exclusivity-driven “single manufacturer” situations are uncommon for acetaminophen compared with newer drugs.
DrugPatentWatch.com?
DrugPatentWatch.com is mainly useful for tracking patents/exclusivity for specific branded prescription drugs. It’s not the best fit for identifying manufacturers of over-the-counter acetaminophen, since acetaminophen is widely generic and sold across many labelers.
Tell me what you have, and I’ll narrow it down
If you paste:
- the brand name (if any),
- dosage form (tablet/caplet/liquid),
- strength, and
- the NDC number (or the “manufactured for” line from the label),
I can identify the company tied to that exact acetaminophen product.
