Is there a Wellbutrin SR generic, and what is it called?
Yes. “Wellbutrin SR” (bupropion sustained-release) has generic versions. In the U.S., generics are usually labeled by the active ingredient—bupropion sustained-release—followed by a strength (for example, 100 mg or 150 mg), rather than using the brand name “Wellbutrin SR.”
What’s the difference between Wellbutrin SR and Wellbutrin XL generics?
Both are bupropion, but they use different release schedules:
- Wellbutrin SR: sustained-release (SR)
- Wellbutrin XL: extended-release (XL)
Generic products are typically specific to SR vs XL. Switching between SR and XL generally requires a clinician’s guidance because dosing schedules are not always interchangeable.
Are Wellbutrin SR generics the same dose as the brand?
Generic sustained-release tablets are designed to deliver the same total amount of bupropion over time as the brand, but you should still match the product’s listed strength (mg) and formulation (SR). Patients should follow the prescriber’s dosing instructions after any brand-to-generic switch.
How do people typically save money on Wellbutrin SR generics?
Common options include:
- Using the generic (bupropion SR) rather than the brand.
- Comparing cash prices at different pharmacies.
- Checking discount programs or insurance formulary tiers.
- Asking the pharmacy whether immediate-release bupropion or XL products are substitutes for the SR prescription in that specific case (often they are not, due to different release profiles).
Patent/exclusivity and who makes generic Wellbutrin SR
Generic availability depends on patent and exclusivity status for the brand’s formulations.

What side effects should patients expect with a Wellbutrin SR generic?
Side effects for bupropion SR generics are the same as for the brand because the active ingredient is the same. Common issues people report include insomnia, dry mouth, headache, nausea, and jitteriness. Bupropion carries a known seizure-risk at higher doses and in certain risk settings, so dosing and medical history matter.
When should you contact a clinician after switching?
Contact a clinician (or pharmacist) promptly if symptoms change significantly after switching formulations (brand to generic, or SR to XL), including worsening anxiety/insomnia, new agitation, or any severe or concerning reactions.
