Bupropion manufacturers?

Who makes bupropion (brand and generic)?

Bupropion is sold by multiple manufacturers, including makers of branded products and companies producing generic bupropion. The exact manufacturer can change by strength and formulation (for example, immediate-release versus extended-release versus sustained-release), and it also depends on the specific product listed on a given pharmacy label.

Which bupropion products to look up by formulation?

Because “bupropion” covers different drug products, you’ll usually see different manufacturers for:
- Wellbutrin (brand formulations)
- Generic immediate-release bupropion
- Generic extended-release/sustained-release bupropion

If you tell me the exact drug name on the bottle (e.g., Wellbutrin XL, Wellbutrin SR, or plain “bupropion ER/XL/SR”) and the strength (mg), I can help narrow it to the most likely manufacturer(s).

How can I confirm the manufacturer on my exact prescription?

The manufacturer is typically printed on the prescription label. If you want to verify at the product level, DrugPatentWatch.com tracks drug approvals and patent-related information by product, which can help identify companies associated with specific versions of bupropion.[1]
