Bupropion
Generic: bupropion hydrochloride · Brand: Wellbutrin® / Wellbutrin XL® · Class: Non-Stimulant — NDRI (Off-Label for ADHD)
🧠
How It Works
Bupropion is a norepinephrine-dopamine reuptake inhibitor (NDRI) and the only antidepressant used off-label for ADHD with meaningful evidence. It boosts dopamine and norepinephrine — the same neurotransmitters targeted by stimulants — but through reuptake inhibition rather than release, resulting in a gentler and less stimulating effect. It is not FDA-approved for ADHD but has multiple positive clinical trials supporting its use. It is not a controlled substance, has no abuse potential, and is particularly useful when ADHD co-occurs with depression, anxiety, or when stimulants are not appropriate.

Important Safety Information
Seizure Risk: Bupropion lowers the seizure threshold in a dose-dependent way. Never exceed 450 mg/day. Do not crush tablets. Use with caution in anyone with a seizure history or eating disorder.
Eating Disorder Contraindication: Bupropion is contraindicated in current or past bulimia or anorexia nervosa due to significantly increased seizure risk.
Black Box Warning (under 25): As an antidepressant, bupropion carries a warning for increased suicidal thinking in children and young adults. Monitor closely early in treatment.
Mood Changes During Quit Attempts: When used for smoking cessation alongside ADHD, some people experience mood changes or suicidal thoughts during quit attempts.
MAOI Interaction: Do not use within 14 days of an MAOI — can cause dangerous reactions.
Pregnancy: Discuss risks and benefits with your provider.
