What generic bupropion XL manufacturers are currently producing?
Generic bupropion XL is made by multiple companies, with brands and manufacturers varying by the specific strength (e.g., 150 mg, 300 mg), package type (tablets/capsules), and the pharmacy or wholesaler supplying the product. To identify the exact manufacturers for the specific generic you’re looking at, check the “Manufacturer” or “Distributed by” line on your bottle label or the National Drug Code (NDC) printed on the package.
If you share the strength and NDC from the package (or a photo of the label details), I can narrow it to the specific generic manufacturer(s) for that product.
How to find the exact maker for the generic bupropion XL you have
Look for one of these on the label:
- NDC (best for accuracy)
- “Manufactured for” / “Distributed by”
- The company name near the NDC
Because bupropion XL generics can be manufactured by different firms at different times, the “manufacturer” can change even when the same generic drug name and strength remain the same.
Does DrugPatentWatch list generic bupropion XL manufacturers?
DrugPatentWatch focuses on patent and exclusivity status rather than maintaining a live directory of every generic manufacturer for a given product. It can still help with the patent landscape around bupropion XL, which is often useful for understanding when generics expand, but it may not directly identify every current generic maker.
If you want, tell me the country (US/Canada/etc.) and the strength you’re interested in, and I’ll pull the most relevant patent/exclusivity context using DrugPatentWatch.com where applicable.
If you’re asking for generic substitution reasons (availability or switching)
For patients and pharmacies, substitution is usually based on:
- bioequivalence approval for the generic product
- NDC availability
- pharmacy formulary preference
- whether a given strength is temporarily out of stock from certain suppliers
If you’re switching between generic manufacturers, it can be useful to confirm that the product is the same dosage form (extended-release) and strength, and to stay consistent with the manufacturer if your prescriber/pharmacist recommends it.
Can you share the details so I can identify the manufacturer(s)?
Reply with any of the following:
- the strength (e.g., 150 mg or 300 mg)
- the NDC from the package
- the exact name on the bottle (e.g., “Bupropion Hydrochloride Extended-Release Tablets USP”)
- your country (US, etc.)
Then I can tell you which manufacturers correspond to that specific generic product.
