Is it safe to take Wellbutrin (bupropion) and Adderall (amphetamine and dextroamphetamine) together?

Combining Wellbutrin and Adderall: Safety and Clinical Considerations

Yes, Wellbutrin (bupropion) and Adderall (amphetamine/dextroamphetamine) can be safely combined for most patients, but this combination requires careful monitoring for seizure risk, cardiovascular effects, and neuropsychiatric symptoms. 1

Primary Safety Concern: Seizure Risk

The most critical consideration when combining these medications is the additive seizure risk:

• Bupropion carries a baseline seizure risk of approximately 0.1% at therapeutic doses 2, 3, which increases to less than 1 per 100 at higher inpatient doses 3
• Amphetamines (Adderall) also lower the seizure threshold, though the exact risk is less well-quantified 4
• When combined, these agents may have additive or potentially synergistic effects on seizure risk 5

Absolute Contraindications

Avoid this combination entirely in patients with: 1, 5

• History of seizures or seizure disorder
• Brain metastases or structural brain lesions
• Eating disorders (anorexia nervosa or bulimia)
• Abrupt withdrawal from alcohol or benzodiazepines
• Conditions that lower seizure threshold

Clinical Efficacy and Rationale

Despite the seizure concerns, this combination has legitimate clinical applications:

• Bupropion has demonstrated equivalent efficacy to methylphenidate for ADHD treatment in controlled trials, with mean effective doses of 3.3 mg/kg/day 6
• Both medications work through dopaminergic and noradrenergic mechanisms, providing complementary therapeutic effects 4, 6
• The combination may be particularly useful when treating comorbid ADHD and depression, or when addressing ADHD in patients with substance abuse history 7

Required Monitoring Parameters

Cardiovascular Monitoring

• Monitor blood pressure and heart rate regularly, as both medications can cause tachycardia and hypertension 4, 1
• Consider baseline and follow-up ECGs in patients with cardiac risk factors 2
• Watch for chest pain, palpitations, or other cardiovascular symptoms 4

Neuropsychiatric Monitoring

The National Comprehensive Cancer Network recommends monitoring for: 1

• Agitation and restlessness (common with both agents)
• Mood changes and irritability
• Insomnia and sleep disturbances
• Anxiety symptoms
• Hallucinations (rare but reported) 8

Seizure Precautions

• Educate patients to report any "spells," unusual sensations, or loss of consciousness immediately 5
• Avoid dose escalation beyond recommended maximums (bupropion: 450 mg/day; Adderall: 50 mg/day) 4, 8
• Be particularly cautious with the sustained-release formulations and ensure proper dosing intervals 5

Common Adverse Effects

Patients should expect: 2, 8

• Gastrointestinal symptoms (nausea, vomiting, constipation)
• Dry mouth
• Headache and dizziness
• Tremor
• Insomnia
• Sweating
• Agitation (most common reason for discontinuation at 9.1%) 3

Practical Dosing Strategy

Start conservatively and titrate slowly:

• Begin with bupropion SR 100-150 mg daily or XL 150 mg daily, then increase gradually 4
• Adderall should start at 10 mg daily, increasing by 5 mg weekly as needed 4
• Maximum bupropion dose: 450 mg/day (divided doses for SR formulation) 4
• Maximum Adderall dose: 50 mg/day 4

Special Populations

Pregnancy and Lactation

• Both medications appear relatively safe in pregnancy, with no consistent evidence of major congenital malformations 4
• Possible small increased risks for preterm birth with continued stimulant use in second half of pregnancy (aRR 1.30) 4
• Monitor breastfed infants carefully for irritability, insomnia, and feeding difficulties 4
• Two case reports exist of seizures in breastfed infants exposed to bupropion 4

Substance Abuse History

• Bupropion is specifically recommended over stimulants alone when treating ADHD in substance-abusing individuals 7
• Methylphenidate and dextroamphetamine have abuse potential (23% nonmedical use in one adolescent substance abuse treatment cohort) 7

Key Clinical Pitfalls to Avoid

1. Never combine in patients with eating disorders - both the psychiatric condition and potential purging behaviors dramatically increase seizure risk 2, 5
2. Watch for medication interactions - bupropion metabolism is not significantly affected by most drugs, but be aware of other seizure threshold-lowering medications 2
3. Don't ignore "minor" neurological symptoms - what patients describe as "spells" or dizziness may represent subclinical seizure activity 5
4. Avoid abrupt discontinuation - taper gradually to prevent discontinuation syndrome, particularly with bupropion 2

When to Choose Alternative Strategies

Consider atomoxetine or other non-stimulant ADHD medications instead if: 4, 7

• Patient has any seizure risk factors
• History of significant cardiovascular disease
• Active substance use disorder where stimulant diversion is a concern
• Patient experiences intolerable side effects with the combination
