- Antipsychotics (e.g., phenothiazines, haloperidol) - may antagonize stimulant effects.
- Propoxyphene - increased dextroamphetamine levels.
Moderate Interactions
- Adrenergic blockers (e.g., beta-blockers) - may reduce stimulant effects.

Monitoring
Baseline Monitoring
Rationale: Stimulants can increase BP and HR; screen for pre-existing cardiovascular conditions.
Timing: Prior to initiation
Rationale: Stimulants can cause appetite suppression and growth suppression.
Timing: Prior to initiation
Rationale: Stimulants can exacerbate or unmask psychiatric conditions.
Timing: Prior to initiation
Rationale: To identify individuals at higher risk for cardiovascular events.
Timing: Prior to initiation
Routine Monitoring
Frequency: At each visit or every 3-6 months

Action Threshold: Sustained elevation (e.g., >95th percentile for age/sex or significant increase from baseline) warrants investigation and potential dose adjustment or discontinuation.
Frequency: Every 3-6 months
Target: Consistent growth trajectory
Action Threshold: Significant growth deceleration or weight loss warrants nutritional assessment and potential drug holiday or alternative therapy.
Frequency: At each visit
Target: Stable mood and behavior
Action Threshold: Emergence of new or worsening psychiatric symptoms warrants immediate evaluation and potential discontinuation.
Frequency: At each visit
Target: Improved focus, reduced hyperactivity/impulsivity, improved wakefulness
Action Threshold: Lack of efficacy or intolerable side effects warrants dose adjustment or change in therapy.

Special Patient Groups
Pregnancy
Dextroamphetamine is classified as Pregnancy Category C. Studies in animals have shown adverse effects on the fetus, and there are no adequate and well-controlled studies in pregnant women. Use during pregnancy should only be considered if the potential benefit justifies the potential risk to the fetus. Neonates exposed to amphetamines during the third trimester may experience withdrawal symptoms.
Trimester-Specific Risks:
Lactation
Dextroamphetamine is excreted into breast milk. The American Academy of Pediatrics considers amphetamines to have 'unknown effect on nursing infant; potential for concern'. Due to the potential for serious adverse reactions in breastfed infants (e.g., irritability, poor feeding, sleep disturbances, weight loss, cardiovascular effects), a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. Monitoring the infant for adverse effects is recommended if use is unavoidable.
Pediatric Use
Dextroamphetamine is approved for ADHD and narcolepsy in children 6 years and older. Close monitoring of growth (height and weight) is essential due to potential for growth suppression. Cardiovascular and psychiatric monitoring is also crucial, as children may be more susceptible to these side effects. Not recommended for children under 3 years of age for ADHD or under 6 years for narcolepsy.
Geriatric Use
Use with caution in elderly patients, generally starting at lower doses and titrating slowly, due to increased sensitivity to stimulant effects and potential for comorbidities (e.g., cardiovascular disease, glaucoma, hyperthyroidism) that may be exacerbated by stimulants. Renal function should be considered, as excretion may be reduced in the elderly.
Clinical Information
Clinical Pearls
- Dextroamphetamine has a high abuse potential; careful patient selection and monitoring are crucial.
- Administer the last dose several hours before bedtime to minimize insomnia.
- Monitor blood pressure and heart rate regularly, especially in patients with pre-existing cardiovascular conditions.
- Monitor growth parameters (height and weight) in pediatric patients due to the risk of growth suppression.
- Educate patients and caregivers about the signs of psychiatric adverse events (e.g., psychosis, mania, aggression) and the importance of reporting them immediately.
- Avoid co-administration with MAOIs due to the risk of hypertensive crisis.
- Urine pH significantly affects dextroamphetamine excretion; acidic urine increases excretion, while alkaline urine decreases it, potentially leading to higher drug levels.
Alternative Therapies

- Dexmethylphenidate (Focalin)
- Atomoxetine (Strattera)
- Guanfacine (Intuniv)
- Clonidine (Kapvay)
