Quick answer
Can you take Zepbound with Bupropion (Wellbutrin)? Generally compatible — no clinically significant interaction known.
- Severity
- none known
- Interaction type
- none
- Monitoring focus
- Standard mental health follow-up; blood pressure monitoring per bupropion prescribing information.
Always confirm with your prescriber. This is educational and based on FDA label data.
Key takeaways
- • Severity: No clinically significant interaction known.
- • Zepbound (weight management (FDA-approved obesity)) and Bupropion (Wellbutrin) (Atypical antidepressant).
- • Clinical management: No dose adjustment required. Defer all decisions to the prescriber.
- • Monitoring: Standard mental health follow-up; blood pressure monitoring per bupropion prescribing information.
Mechanism
No known pharmacokinetic interaction. Bupropion is metabolized via CYP2B6; tirzepatide does not affect CYP enzymes. Both can reduce appetite, but this is an additive desired effect in patients on tirzepatide for weight management, not an adverse interaction.
Clinical management
No dose adjustment required. Defer all decisions to the prescriber.
GLP1Zoom does not prescribe medications or recommend dose changes. Always confirm any adjustment with your prescribing clinician before changing how you take Zepbound or Bupropion (Wellbutrin).
