Generic brand for wellbutrin?

What generic brand can replace Wellbutrin?

Wellbutrin is the brand name for bupropion, so the “generic brand” you’ll usually see is simply bupropion (often written as bupropion hydrochloride). The generic will be labeled by the dosage form:

- bupropion IR (immediate-release)
- bupropion SR (sustained-release)
- bupropion XL (extended-release)

Those correspond to common Wellbutrin products:
- Wellbutrin IR → bupropion IR
- Wellbutrin SR → bupropion SR
- Wellbutrin XL → bupropion XL

Is there more than one generic version?

Yes. Because Wellbutrin comes in different release types, pharmacies may offer different bupropion generics depending on which Wellbutrin you were prescribed (IR vs SR vs XL). Switching release types can change how often you take it and how the medicine is absorbed.

What should you ask your pharmacist about before switching?

Ask for the exact “release” match to your prescription (IR, SR, or XL) and confirm:
- the strength (for example, 150 mg, 300 mg)
- the dosing schedule (once daily vs multiple times per day)
- whether it’s the same formulation your prescriber intended
