BuSpar vs Wellbutrin
Two very different medications — understanding when each is best
The Bottom Line
BuSpar is for anxiety. Wellbutrin is for depression. They work very differently and are used for different purposes. Sometimes they're used together because they complement each other well.

| Sexual Side Effects | Rare | Rare (may improve) |
| Sedation | No | No (may be activating) |
| Addiction Potential | None | None |
BuSpar (Buspirone)
BuSpar is specifically designed to treat generalized anxiety disorder (GAD). It's not an antidepressant and doesn't help depression on its own.
Best For:
- Generalized anxiety disorder
- Anxiety without depression
- Add-on to SSRIs for anxiety
- Those who can't tolerate SSRIs
Key Points:
- • Takes 2-4 weeks to work
- • Not for as-needed use
- • Non-addictive
- • Must be taken regularly
Wellbutrin (Bupropion)
Wellbutrin is an antidepressant that works on dopamine and norepinephrine. It's energizing and doesn't cause weight gain or sexual side effects.
Best For:
- Depression (especially with fatigue)
- Smoking cessation
- ADHD symptoms (off-label)
- Those who gained weight on SSRIs
Key Points:
- • Energizing, not sedating
- • Weight neutral or loss
- • No sexual side effects
- • Can worsen anxiety in some
Can You Take Them Together?
Yes! BuSpar and Wellbutrin are actually a good combination for some patients. They work through completely different mechanisms and don't interact significantly.
This combination might work well for:
- • Depression with significant anxiety
- • When an SSRI isn't desired (weight/sexual side effects)
- • ADHD with anxiety
- • Depression with low energy AND anxiety

- ✓ Your main problem is anxiety
