Is bupropion the same as Wellbutrin?
Yes. Wellbutrin is a brand name for the drug bupropion. Different forms of Wellbutrin (such as immediate-release or extended-release) contain bupropion but with different release patterns. [1]
What are the common Wellbutrin/bupropion brand versions?
You may see Wellbutrin listed under different formulations, often written as:
- Wellbutrin (commonly immediate-release in many markets)
- Wellbutrin SR (sustained release)
- Wellbutrin XL (extended release)
All of these are bupropion, just in different tablet-release designs. [1]
Is it used for the same conditions?
Bupropion (including the Wellbutrin brands) is commonly used for depression and to help with smoking cessation, depending on the specific product and prescribing guidance. [1]
Are there any practical differences for patients?
The main difference is the release schedule and dosing frequency, which can affect how it feels (for example, steady blood levels with SR/XL vs more frequent dosing with immediate-release). The active ingredient is still bupropion. [1]
