Is it safe to take bupropion (Wellbutrin) together with lisdexamfetamine (Vyvanse) 70 mg daily, amphetamine/dextroamphetamine (Adderall) 20 mg daily, and duloxetine 60 mg daily?

This combination is NOT safe and should NOT be used

Taking bupropion (Wellbutrin) with both Vyvanse 70mg daily AND Adderall 20mg daily, plus duloxetine 60mg daily creates multiple serious safety concerns that outweigh any potential benefits.

Critical Safety Issues

1. Dual High-Dose Stimulant Therapy is Inappropriate

You are currently taking two different amphetamine-based stimulants simultaneously at substantial doses:

• Vyvanse (lisdexamfetamine) 70mg = converts to approximately 20.8mg d-amphetamine 1
• Adderall 20mg = mixed amphetamine salts

This dual stimulant regimen is not standard practice and significantly increases risks when adding bupropion. There is no evidence supporting the safety or efficacy of combining two different amphetamine products at these doses 2.

2. Seizure Risk is Substantially Elevated

Bupropion lowers the seizure threshold, and this risk is dose-dependent and dramatically increased when combined with stimulants 3, 4:

• Bupropion alone carries a seizure risk of approximately 0.4-0.48% at maximum recommended doses 4
• Stimulants can further lower seizure threshold 5
• The combination of bupropion with any stimulant requires extreme caution 2
• Your total stimulant burden (Vyvanse + Adderall) is exceptionally high, compounding this risk

The FDA drug label for bupropion specifically warns about seizure risk, particularly with conditions that lower seizure threshold 5. While there are "no studies of the combination of bupropion and stimulants," clinicians are advised to "proceed with caution" 2.

3. Serotonin Syndrome Risk with Duloxetine

Adding bupropion to duloxetine creates potential for serotonin syndrome, though the risk is lower than with pure SSRIs 6, 7:

• Duloxetine is a serotonin-norepinephrine reuptake inhibitor (SNRI)
• Bupropion has "milder effects on serotonergic activity" but can inhibit cytochrome P450 2D6, increasing duloxetine blood levels 7
• Stimulants (particularly amphetamines) can contribute to serotonergic effects 6
• One case report documented serotonin syndrome from bupropion + SSRI combination 7

Symptoms to monitor: confusion, agitation, myoclonus, tremors, hyperreflexia, tachycardia, hypertension, diaphoresis—these can be fatal if untreated 6.

4. Cardiovascular Risks are Compounded

All three medications increase cardiovascular stress:

• Both stimulants cause tachycardia and hypertension 1
• Bupropion increases heart rate and blood pressure 8
• Duloxetine can cause blood pressure increases 9

The additive cardiovascular burden from this four-drug combination is substantial and potentially dangerous.

5. Neuropsychiatric Adverse Effects

• Bupropion carries a black box warning for suicidal ideation in young adults 8, 4
• The combination with stimulants can cause agitation, anxiety, insomnia, and mood instability 5, 10
• Adding bupropion to your current regimen may worsen these effects

Evidence on Bupropion + Duloxetine (Without Stimulants)

When used without stimulants, the bupropion-duloxetine combination shows:

• Modest efficacy for treatment-resistant depression 11, 12
• Generally tolerable side effect profile 11, 13
• Common adverse effects: nausea, dry mouth, jitteriness, insomnia 11

However, these studies specifically excluded patients on stimulants and did not involve dual high-dose amphetamine therapy.

What You Should Do

Immediate Actions:

1. Do NOT start bupropion with your current medication regimen
2. Consult your prescriber immediately about why you're taking two different stimulants simultaneously—this is highly unusual
3. Request a comprehensive medication review to rationalize your regimen

Safer Alternatives:

If additional treatment is needed for depression or other indications:

For depression with your current stimulants + duloxetine:

• Optimize duloxetine dosing first (can go up to 120mg if needed) 9
• Consider augmentation with non-serotonergic, non-stimulating agents
• Psychotherapy should be prioritized 14

If bupropion is truly necessary:

• First, consolidate to a single stimulant at an appropriate dose 2
• Use the lowest effective bupropion dose (start 150mg once daily maximum) 3
• Close monitoring for seizures, cardiovascular effects, and serotonin syndrome is mandatory

Critical Pitfalls to Avoid

1. Never assume "more medications = better control"—polypharmacy at these doses creates exponential risk
2. Do not self-adjust doses of any of these medications
3. Recognize early warning signs: new-onset tremor, confusion, chest pain, palpitations, or mood changes require immediate medical attention
4. Avoid alcohol completely—it further lowers seizure threshold with bupropion 4

The mortality and morbidity risks of this four-drug combination, particularly with dual stimulants, are unacceptably high and are not justified by any evidence-based indication.
