Contraindications for Vyvanse (Lisdexamfetamine)
Vyvanse is absolutely contraindicated in two situations: patients with known hypersensitivity to amphetamine products or any ingredient in Vyvanse, and patients currently taking or who have taken MAO inhibitors within the past 14 days. 1
Absolute Contraindications
1. Hypersensitivity Reactions
- Known hypersensitivity to amphetamine products or any ingredient in Vyvanse
- This includes patients with prior history of:
- Anaphylactic reactions
- Stevens-Johnson Syndrome
- Angioedema
- Urticaria 1
2. MAO Inhibitor Use
- Concurrent use with MAOIs or within 14 days of stopping MAOIs
- This includes MAOIs such as linezolid or intravenous methylene blue
- Critical reason: Risk of hypertensive crisis and potential cerebrovascular accident 2, 1
Additional Clinical Contraindications from Stimulant Guidelines
While the FDA label specifies only two absolute contraindications, clinical practice guidelines identify additional situations where Vyvanse should not be used 2:
Psychiatric Contraindications
- Active psychotic disorders: Schizophrenia, psychosis NOS, or manic episodes with psychosis
- Stimulants are known psychotomimetics and will exacerbate psychotic symptoms 2
Cardiovascular Contraindications
- Serious structural cardiac abnormalities or serious cardiac disease
- Risk of sudden death in patients with underlying heart problems or heart defects 3, 1
- This includes:
- Cardiomyopathy
- Serious cardiac arrhythmias
- Coronary artery disease
Other Contraindications
- Glaucoma: Sympathomimetics may increase intraocular pressure 2, 3, 2, 3
- Uncontrolled hypertension 3
- Hyperthyroidism 3
- Agitated states 3
Important Clinical Caveats
Not Absolute Contraindications (Despite Package Insert Warnings)
Recent evidence suggests these conditions may NOT be absolute contraindications 2:
- Motor tics or Tourette's syndrome: Controlled studies have not found that stimulants consistently worsen tics
- History of substance abuse: While requiring careful monitoring, even prior stimulant abuse may not represent an absolute contraindication if the patient can be supervised closely
Conditions Requiring Extreme Caution
- Drug dependence history: Black box warning exists, but patients can be treated with intensive monitoring 2
- Peripheral vasculopathy: May worsen conditions including Raynaud phenomenon 3
Monitoring Requirements When Prescribing
Even when not contraindicated, monitor for:
