Lisdexamfetamine + Rasagiline

STOP — Contraindicated

FDA contraindication. Same risk as other amphetamine + MAO inhibitor combinations.

Evidence level: STRONG

What this interaction means

Vyvanse (lisdexamfetamine) with rasagiline can cause a dangerous blood pressure crisis. Since Vyvanse is converted to amphetamine in your body, the same MAO inhibitor contraindication applies.

How it works (mechanism)

Same mechanism as amphetamine + MAO inhibitor. Lisdexamfetamine is a prodrug converted to dextroamphetamine. FDA labels contraindicate concurrent use.

Practical advice

Do not take Vyvanse with any MAO inhibitor including rasagiline. A 14-day washout from MAO inhibitor is required.

Timing

Take Lisdexamfetamine in the morning (or early afternoon for IR boosters) to avoid insomnia. Rasagiline follows its prescribed schedule. Acidic foods/drinks can reduce stimulant absorption — take on an empty stomach or with a non-acidic snack.

Risk factors

Higher risk for: those with cardiovascular conditions, hypertension, anxiety disorders, history of seizures, concurrent caffeine or sympathomimetic use, elderly, or those with hyperthyroidism.

Symptoms to watch for

Severe headache, chest pain, rapid heartbeat, very high blood pressure, high fever

What to tell your doctor

Coordinate care between treating physicians. Discuss non-stimulant alternatives. Observe 14-day washout period.

Safer alternatives

Stimulant combinations can increase cardiovascular strain. Reduce caffeine intake and avoid other stimulating supplements. Discuss with your prescriber: non-stimulant ADHD options (atomoxetine, guanfacine) or L-theanine for focus without the sympathomimetic load.
