Bupropion and wellbutrin the same?

Yes—Wellbutrin is simply the most common brand name for the drug bupropion. In the United States, Wellbutrin is marketed by Pfizer (and now also by other companies under the generic name), while in other parts of the world you’ll find it sold as Aplenzin (another brand) or simply as “bupropion” once it’s available in generic form.

What they share

Why the brand name matters

1. Dosage forms – Wellbutrin is available as immediate‑release, sustained‑release (SR), and extended‑release (XL). The generic can be found in similar formulations, but you’ll see the brand name on the label for the XL version most often.
2. Price – Once the drug goes generic, the price drops dramatically. The brand name often carries a premium.
3. Availability – Some patients can’t get the brand (e.g., in a pharmacy that only stocks generics), but the generic will provide the same active drug.

A quick comparison of the major formulations

Side‑effects and safety

• The most common side‑effects are insomnia, dry mouth, headache, and weight loss.
• Because bupropion lowers the seizure threshold, it should be avoided or used with caution in people with a history of seizures, eating disorders (like anorexia or bulimia), or who are taking other seizure‑inducing meds.
• It can interact with MAO inhibitors, other antidepressants, and certain blood‑pressure meds, so your clinician will review all your meds before starting.

Bottom line

Wellbutrin = bupropion. The brand name is just a marketing label. The underlying chemistry, therapeutic uses, and safety profile are the same whether you get it as a brand‑name pill or a generic tablet. If you’re considering switching or have questions about dosing or side‑effects, talk with your prescriber—they’ll help pick the right formulation for you.
