Can you take Wellbutrin with Ozempic or Wegovy?

Yes — there's no documented dangerous interaction between bupropion (Wellbutrin) and GLP-1 medications. They're commonly co-prescribed. Considerations: both can suppress appetite (bupropion mildly, GLP-1 strongly), both can raise heart rate slightly, and bupropion lowers seizure threshold — relevant only if you have seizure risk factors.

Isn't bupropion already in a weight-loss drug?

Yes — bupropion is half of Contrave (bupropion + naltrexone), an FDA-approved weight-loss medication. Bupropion alone has modest weight-neutral-to-weight-loss effects, which is why it's often chosen for depressed patients concerned about weight. Combining it with GLP-1 is common and generally well-tolerated.

Will Wellbutrin and GLP-1 together cause too much weight loss?

Possibly — bupropion's mild appetite suppression adds to GLP-1's strong effect. Most users find the combination manageable, but watch for losing more than ~2 lbs/week consistently, difficulty eating enough protein, or persistent fatigue. Your prescriber can adjust doses if suppression is excessive.

Does GLP-1 affect how Wellbutrin is absorbed?

Potentially slightly — GLP-1's delayed gastric emptying can slow absorption of oral medications. For extended-release bupropion (XL/SR) this is usually not clinically significant. If you notice mood changes or feel the medication works differently after starting GLP-1, tell your prescriber.

Is there a seizure risk combining Wellbutrin and GLP-1?

Bupropion lowers seizure threshold — its main safety caveat. GLP-1s don't affect seizure risk directly, but severe vomiting/diarrhea (GLP-1 side effects) can cause electrolyte imbalances that theoretically compound risk in susceptible people. If you have any seizure history or risk factors, your prescriber should know before combining.

Should I tell my GLP-1 prescriber I take Wellbutrin?

Yes — always disclose all medications. Bupropion affects appetite, heart rate, and seizure threshold — all relevant to GLP-1 prescribing. Your prescriber needs the full picture to dose safely and interpret side effects correctly.

GLP-1 and Wellbutrin: Bupropion Interactions With Ozempic & Zepbound 2026

The short answer

Yes, Wellbutrin (bupropion) and GLP-1 medications are commonly taken together with no documented dangerous interaction. In fact, bupropion has its own weight-loss pedigree — it's half of Contrave, the FDA-approved bupropion/naltrexone combination for weight management. The combination with GLP-1 is generally well-tolerated, with a few things worth watching.

The Contrave connection

Bupropion is unusual among antidepressants: where most cause weight gain, bupropion is weight-neutral to mildly weight-negative — which is why it's paired with naltrexone in Contrave and why psychiatrists often choose it for patients concerned about weight. If you're on bupropion for depression or smoking cessation and starting GLP-1, you're stacking two weight-favorable mechanisms — generally a feature, not a bug.

Where the two drugs overlap

Effect	Wellbutrin	GLP-1	Combined
Appetite	Mildly suppressed	Strongly suppressed	Additive — watch under-eating
Heart rate	Mildly increased	Mildly increased (1-3 bpm)	Additive — usually fine
Seizure threshold	Lowered (main caveat)	No direct effect	Watch electrolytes if severe GI
Absorption	Oral, extended-release	Slows gastric emptying	Possibly delayed onset

The seizure question — the one real caveat

Bupropion's main safety warning is dose-related seizure risk — it lowers the seizure threshold, which is why it's contraindicated in eating disorders with purging (electrolyte disturbance compounds the risk). GLP-1s don't affect seizure threshold directly, but severe vomiting or diarrhea — occasional GLP-1 side effects — can cause the same electrolyte imbalances. For the vast majority of users this is theoretical; if you have any seizure history, eating disorder history, or heavy alcohol use, make sure your prescriber knows before combining.

Practical guidance

Disclose both medications to both prescribers — your psychiatrist and GLP-1 provider should each know the full picture.
Watch for excessive appetite suppression — scheduled protein-first meals regardless of hunger.
Report mood changes — if bupropion feels different after starting GLP-1 (absorption timing), tell your prescriber.
Stay hydrated — protects against the electrolyte edge case and helps GLP-1 side effects generally.
