What brand names does bupropion come in?
Bupropion is sold under multiple brand names depending on the product type (immediate-release vs. extended-release vs. sustained-release vs. for smoking cessation). Commonly searched brand names include:
- Wellbutrin (bupropion hydrochloride; often used for depression)
- Wellbutrin XL (extended-release bupropion)
- Wellbutrin SR (sustained-release bupropion)
- Zyban (bupropion used to help people stop smoking)
What’s the difference between Wellbutrin, Wellbutrin XL, and Wellbutrin SR?
These are different bupropion formulations (different release timing), which can affect dosing schedules:
- Wellbutrin is typically associated with immediate-release formulations.
- Wellbutrin SR is a sustained-release version.
- Wellbutrin XL is an extended-release version.
Are there any other bupropion brand names?
Zyban is the main brand name for smoking-cessation use. Other brand names exist in some countries, but the best-known U.S. brands are Wellbutrin (and its XL/SR versions) and Zyban.
Can bupropion be confused with other antidepressants?
Yes. The names above are bupropion brands; they are not the same as other antidepressants with different active ingredients (for example, sertraline or fluoxetine). If you’re trying to confirm what you have, check the active ingredient on the label.
What should patients look for on the prescription bottle?
Look for:
- Active ingredient: bupropion (often listed as bupropion HCl)
- Product name: Wellbutrin / Wellbutrin SR / Wellbutrin XL / Zyban
- Strength (mg) and whether it’s SR or XL, since that affects how it’s taken.
