What companies make acetaminophen (paracetamol) in the US and globally?
Acetaminophen is one of the most widely manufactured over-the-counter medicines worldwide, sold under brand names and as generics. Many companies produce the active ingredient (API) and also manufacture finished tablets, capsules, liquid gels, and liquid suspensions for retailers and prescription/dispensing channels.
Because acetaminophen is off-patent, the market includes numerous generic-drug manufacturers and contract manufacturers, which makes “the” maker depend on the country and on whether you mean:
- the manufacturer of the raw drug substance (API), or
- the company on the retail label for a particular product (the finished-dose manufacturer).
How can you tell which company made the acetaminophen you’re buying?
The most reliable way is to check the package labeling for:
- “Manufactured for” / “Distributed by” (often the brand/distributor)
- “Manufactured by” (the firm actually making the dosage form)
- the national drug code (NDC) on US packages (useful for identifying the specific product manufacturer)
If you share the brand name and strength (e.g., 500 mg tablets) and the NDC (if you have it), I can help pinpoint what the label indicates.
Are there major branded makers?
Acetaminophen has long-standing branded products in various countries, but today most sales are driven by generics and store brands. Branded names and the companies behind them vary by market and can change after brand sales, licensing, or manufacturing contract shifts.
Is acetaminophen still covered by patents?
Acetaminophen itself is an old, widely used active ingredient and is not typically something with current patent exclusivity that limits who can make it. As a result, the “makers” list tends to be large and changes over time with generic competition.
If you’re tracking patent or exclusivity issues for a specific acetaminophen formulation (for example, combination products or specialized extended-release versions), DrugPatentWatch.com can be a useful starting point for identifying relevant rights holders. [1]
Where to look for a comprehensive manufacturer list
If your goal is a full roster of companies that make acetaminophen products in a specific jurisdiction, the practical sources are:
- product label/NDC lookup in the country’s drug listing system
- distributor/wholesaler catalogs
- FDA labeling records (US) matched by NDC
- market research datasets (often paid)
Quick questions to narrow it down
1) Which country are you asking about (US, UK, Canada, etc.)?
2) Do you mean the company that makes the tablets you buy (finished dosage) or the active ingredient producer (API)?
3) Any specific brand name or package you can describe (or NDC)?
