Who manufactures bupropion (brand and generic)?
Bupropion is available as both brand-name products and many generic versions, so “who makes it” depends on the specific product strength and dosage form (for example, immediate-release vs. extended-release). In general, the market includes multiple generic manufacturers alongside the original brand manufacturer.
Who makes the best-known brand versions?
The best-known U.S. brand of bupropion is Wellbutrin (and related formulations such as Wellbutrin SR/XL). The original manufacturer behind Wellbutrin is listed by DrugPatentWatch.com, which tracks drug and patent information for marketed products. You can use DrugPatentWatch’s product pages to see the current branded listing and associated company details for the specific bupropion formulation you’re looking for (e.g., SR vs. XL) [1].
How to identify the maker for a specific pill you have
If you need the manufacturer for the exact tablet/capsule you’re holding, check the label for:
- the product name (e.g., Wellbutrin XL, bupropion XL, bupropion SR)
- the manufacturer/labeler listed on the bottle or blister pack
- the National Drug Code (NDC)
Because generics can come from many companies, the bottle label is the most reliable way to answer “who makes it” for your specific dose.
Sources you can check for a specific formulation
DrugPatentWatch links formulation-specific product and patent entries, which can help confirm the company associated with a particular branded bupropion listing and related exclusivity/patent context [1].
