Approved Use
This medication is not approved for weight loss. If you have any questions or concerns, discuss them with your doctor.
Safety Precautions
Avoid operating a vehicle or engaging in activities that require alertness and clear vision until you understand how this medication affects you.
Tolerance and Dependence
Long-term or high-dose use of this medication may lead to tolerance, where the medication becomes less effective, and higher doses may be required to achieve the same effect. If you experience a decrease in the medication's effectiveness, contact your doctor. Do not exceed the prescribed dose.
Additionally, long-term or regular use of this medication may result in dependence. Stopping the medication abruptly may lead to withdrawal symptoms. Consult your doctor before reducing the dose or discontinuing the medication, and follow their instructions carefully. Report any adverse effects to your doctor.
Heart Tests and Monitoring
You may need to undergo heart tests before starting this medication. If you have questions, discuss them with your doctor. This medication may cause high blood pressure, so it is essential to monitor your blood pressure and heart rate as directed by your doctor.
Interactions with Other Medications
This medication may affect the results of certain laboratory tests. Inform all of your healthcare providers and laboratory personnel that you are taking this medication. Before using over-the-counter (OTC) products that may increase blood pressure, such as cough or cold medications, diet pills, stimulants, non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen, and certain natural products or aids, consult your doctor.
Severe Skin Reactions
A severe skin reaction, known as Stevens-Johnson syndrome or toxic epidermal necrolysis, may occur. This condition can cause severe health problems that may be permanent or even fatal. Seek immediate medical attention if you experience symptoms such as red, swollen, blistered, or peeling skin (with or without fever), red or irritated eyes, or sores in your mouth, throat, nose, or eyes.

- Confusion
- Assaultiveness
- Hallucinations
- Panic states
- High fever
- Rhabdomyolysis
- Arrhythmias

What to Do:
Call 911 or Poison Control immediately (1-800-222-1222). Seek emergency medical attention. Management includes symptomatic treatment, gastric lavage, activated charcoal, and sedation for CNS overstimulation.
Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs) (concurrent use or within 14 days of MAOI use) - risk of hypertensive crisis.
Major Interactions
- Serotonergic drugs (e.g., SSRIs, SNRIs, triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, St. John's Wort) - risk of serotonin syndrome.
- Antihypertensive drugs - may decrease the hypotensive effect of these drugs.
- Urinary acidifying agents (e.g., ammonium chloride, ascorbic acid) - increase urinary excretion of amphetamine, decreasing efficacy.
- Urinary alkalinizing agents (e.g., sodium bicarbonate, acetazolamide) - decrease urinary excretion of amphetamine, increasing efficacy and prolonging duration of action.
- Proton Pump Inhibitors (PPIs) and H2-receptor antagonists - may alter gastric pH, potentially affecting absorption (though less significant for lisdexamfetamine due to hydrolysis in blood).
Moderate Interactions
- Tricyclic Antidepressants (TCAs) - may potentiate cardiovascular effects of amphetamines.
- Antipsychotics - may antagonize the stimulant effects of amphetamines.
- Adrenergic blockers (e.g., beta-blockers) - may potentiate the pressor effect of amphetamines.
- Alcohol - may alter absorption or increase adverse effects.
Minor Interactions
- Not available
Monitoring
Baseline Monitoring
Rationale: CNS stimulants can cause increases in BP and HR.
Timing: Prior to initiation of therapy.
Rationale: Monitor for growth suppression in pediatric patients.
Timing: Prior to initiation of therapy.
Rationale: Assess for pre-existing cardiac conditions that may contraindicate stimulant use.
Timing: Prior to initiation of therapy.
Rationale: Assess for pre-existing psychiatric conditions that may be exacerbated by stimulants.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: At each visit or at least every 3-6 months.
Target: Within normal limits for age.
Action Threshold: Persistent elevation above normal range; consider dose reduction or discontinuation.
Frequency: Every 3-6 months (pediatric patients).
Target: Normal growth trajectory.
Action Threshold: Significant growth deceleration or weight loss; consider drug holiday or alternative therapy.
Frequency: At each visit.
Target: Stable mental health.
Action Threshold: New or worsening psychiatric symptoms; consider dose reduction or discontinuation.
Frequency: At each visit.
Target: No signs of abuse or diversion.
Action Threshold: Signs of abuse or diversion; implement appropriate management strategies.
Symptom Monitoring
- Chest pain
- Shortness of breath
- Syncope
- New or worsening psychotic symptoms (e.g., hallucinations, delusions)
- New or worsening manic symptoms
- Aggression or hostility
- New or worsening tics
- Unexplained weight loss
- Growth deceleration (in children)
- Peripheral vasculopathy (e.g., Raynaud's phenomenon)
Special Patient Groups
Pregnancy
Use during pregnancy should be considered only if the potential benefit justifies the potential risk to the fetus. Amphetamines may cause fetal harm, including premature delivery and low birth weight. Neonates exposed to amphetamines during pregnancy may experience withdrawal symptoms.
Trimester-Specific Risks:
Lactation
Lisdexamfetamine and its active metabolite, dextroamphetamine, are excreted into human milk. Due to the potential for serious adverse reactions in breastfed infants (e.g., agitation, insomnia, anorexia, reduced weight gain), breastfeeding is not recommended during treatment.
Pediatric Use
Safety and efficacy established for ADHD in children 6 years and older. Monitor growth (height and weight) regularly, as stimulants can cause growth suppression. Monitor for emergence or worsening of psychiatric symptoms (e.g., psychosis, mania, aggression, tics).
Geriatric Use
Clinical studies did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Clinical Information
Clinical Pearls
- Lisdexamfetamine is a prodrug, meaning it is inactive until converted in the body to dextroamphetamine. This conversion occurs primarily in the blood and is not affected by gastrointestinal pH, which may lead to more consistent absorption compared to immediate-release amphetamines.
- The chewable tablet can be chewed thoroughly and swallowed, or dissolved in water, orange juice, or yogurt and consumed immediately. Do not store the mixture.
- Due to its long duration of action (up to 14 hours), it is typically dosed once daily in the morning to avoid interference with sleep.
- Careful cardiovascular and psychiatric screening is essential before initiating therapy and throughout treatment.
- Patients should be educated on the potential for abuse and dependence, and the importance of taking the medication exactly as prescribed.
- Growth monitoring is crucial for pediatric patients on long-term therapy.
Alternative Therapies
- Other CNS Stimulants (e.g., Methylphenidate, Dextroamphetamine, Mixed Amphetamine Salts)
- Non-stimulants (e.g., Atomoxetine, Guanfacine ER, Clonidine ER)
- Behavioral therapy and psychotherapy (especially for ADHD and BED)
