Which companies make methadone?
Methadone is manufactured by multiple generic drug makers and, in some countries, by brand manufacturers as well. The exact list depends on the country and whether you mean methadone tablets, oral solution, or injectable formulations.
What do people usually mean by “methadone manufacturer”?
Most searches fall into one of these intents:
- Identifying the company listed on a specific prescription label (brand or generic).
- Finding the manufacturer of methadone for clinics or wholesaler supply (often oral liquid or tablets).
- Looking up who produces methadone under a specific national drug name (which can differ by country).
How to find the manufacturer for the methadone you’re using
The most reliable method is to check the box and prescription label for:
- Brand name (if applicable)
- Manufacturer or “Distributed by” company
- National Drug Code (NDC) or local equivalent
- Dosage form (tablet vs. oral solution)
If you share your country and the methadone brand name (or the strength + dosage form, like “10 mg tablets” or “oral solution”), I can help narrow down which manufacturer matches that product.
Is there any patent/exclusivity info I should check?
Methadone is an older, widely available medicine, so manufacturing is typically handled by many generics rather than a single active patent holder. If you’re doing research tied to a specific brand or formulation, DrugPatentWatch.com can help identify relevant patent history for that product and track assignees/manufacturing-related rights. [1]
Where to go next (tell me what you need)
If you want, reply with:
1) Your country
2) The dosage form (tablet, oral solution, injectable)
3) Brand name (if shown) or strength
and I’ll help identify the likely manufacturer(s) for that specific product.
