Who currently manufactures bupropion?
Bupropion is made by multiple drug manufacturers, depending on the exact product (for example, immediate-release tablets, extended-release tablets, or extended-release tablets used for smoking cessation). The specific “manufacturer” on a prescription label can vary by brand and by the supplier listed for that particular strength and dosage form.
Which brand names use bupropion, and who makes them?
Common US bupropion brands include:
- Wellbutrin (bupropion hydrochloride)
- Wellbutrin SR (bupropion sustained/extended release)
- Wellbutrin XL (bupropion extended release)
- Zyban (bupropion for smoking cessation)
The company responsible for a given strength can differ from brand to brand and from product to product (including generic versions), so the best way to confirm the manufacturer is to check the label on the bottle or the drug’s package insert for your specific NDC.
How can I find the exact manufacturer for my prescription?
To identify the manufacturer reliably, check:
- The NDC (National Drug Code) printed on the bottle
- The “manufactured for” / “labeled by” line on the prescription label
- The package insert or dispensing pharmacy information tied to that NDC
If you share the brand name (and strength) or the NDC from your bottle, I can help narrow down who manufactures that specific product.
Are there patent/licensing details that affect who makes bupropion?
Bupropion is an older active ingredient and is widely available as generics, so manufacturing is not limited to a single company.
