Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs) - concurrent use or within 14 days of MAOI discontinuation (risk of hypertensive crisis)
Major Interactions
- Alkalinizing agents (e.g., sodium bicarbonate, acetazolamide, thiazide diuretics) - increase amphetamine plasma levels and prolong half-life
- Acidifying agents (e.g., ascorbic acid, ammonium chloride, cranberry juice) - decrease amphetamine plasma levels and shorten half-life
- Tricyclic Antidepressants (TCAs) - may potentiate cardiovascular effects of amphetamines
- Serotonergic drugs (e.g., SSRIs, SNRIs, triptans, fentanyl, tramadol, St. John's Wort) - increased risk of serotonin syndrome
- Antihypertensive agents - amphetamines may reduce the effectiveness of antihypertensives
- Halogenated Anesthetics - increased risk of sudden death due to ventricular arrhythmias
Moderate Interactions
- Antipsychotics (e.g., phenothiazines, haloperidol) - may antagonize the stimulant effects of amphetamines
- Lithium - may inhibit the stimulant effects of amphetamines
- Proton Pump Inhibitors (PPIs) / H2 Blockers - may increase gastric pH, potentially affecting absorption (less significant for ER formulations)
- CYP2D6 inhibitors (e.g., quinidine, ritonavir, fluoxetine, paroxetine) - may increase amphetamine exposure
Minor Interactions
- Alcohol - may increase risk of adverse events and alter release profile of extended-release formulations (though not specifically for Adzenys XR ODT)
Monitoring
Baseline Monitoring
Rationale: Amphetamines can cause increases in BP and HR; screen for pre-existing cardiovascular conditions.
Timing: Prior to initiation and periodically during treatment.
Rationale: Monitor for growth suppression in pediatric patients.
Timing: Prior to initiation and periodically during treatment.
Rationale: Screen for pre-existing psychiatric conditions that may be exacerbated or unmasked.
Timing: Prior to initiation.
Rationale: Assess risk for abuse and dependence.
Timing: Prior to initiation.
Routine Monitoring
Frequency: At least annually, or more frequently if clinically indicated.
Target: Within normal limits for age and baseline.
Action Threshold: Sustained clinically significant increases (e.g., >10-20 mmHg systolic/diastolic, >10-20 bpm HR) warrant further evaluation and potential dose adjustment or discontinuation.
Frequency: Every 3-6 months in pediatric patients.
Target: Consistent growth trajectory.
Action Threshold: Significant growth deceleration or weight loss warrants evaluation and potential treatment interruption.
Frequency: Regularly at follow-up visits.
Target: Absence of new or worsening symptoms.
Action Threshold: Emergence of severe psychiatric symptoms warrants immediate evaluation and potential discontinuation.
Frequency: Regularly at follow-up visits.
Target: Improved attention, reduced hyperactivity/impulsivity, improved academic/social functioning.
Action Threshold: Lack of efficacy or intolerable side effects warrants dose adjustment or alternative treatment.
Symptom Monitoring
- Chest pain
- Shortness of breath
- Syncope
- Palpitations
- New or worsening aggression
- New or worsening tics/Tourette's syndrome
- Hallucinations
- Delusions
- Mania

- Severe headache
- Numbness, coolness, or pain in digits (Raynaud's phenomenon)

Special Patient Groups
Pregnancy
Use during pregnancy should be avoided unless the potential benefit justifies the potential risk to the fetus. Amphetamines may cause fetal harm, including premature birth and low birth weight. Neonates exposed to amphetamines during the third trimester may experience withdrawal symptoms.
Trimester-Specific Risks:
Lactation
Amphetamine is excreted into human milk. Due to the potential for serious adverse reactions in breastfed infants (e.g., irritability, poor feeding, sleep disturbances, weight loss), breastfeeding is not recommended during treatment with Adzenys XR ODT.
Pediatric Use
Safety and efficacy established in pediatric patients 6 years and older. Long-term effects on growth (weight and height) should be monitored. Psychiatric adverse events (e.g., psychosis, mania, aggression) can occur. Cardiovascular monitoring is essential.
Geriatric Use
Clinical studies did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Generally, 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
- Adzenys XR ODT is an extended-release formulation designed for once-daily morning dosing. Its orally disintegrating tablet form is beneficial for patients who have difficulty swallowing pills.
- The dose of Adzenys XR ODT is expressed in amphetamine base equivalents. Ensure correct conversion if switching from other amphetamine products.
- Counsel patients on the importance of taking the medication early in the morning to avoid insomnia.
- Regular monitoring of blood pressure, heart rate, and growth (in children) is crucial due to potential cardiovascular and growth-related side effects.
- Educate patients and caregivers about the signs of serious psychiatric adverse events (e.g., new-onset psychosis, mania) and the need for immediate medical attention if they occur.
- Due to its abuse potential, proper storage and disposal of Adzenys XR ODT should be emphasized.
Alternative Therapies
- Other amphetamine-based stimulants (e.g., Adderall XR, Vyvanse)
- Methylphenidate-based stimulants (e.g., Concerta, Ritalin LA, Focalin XR, Quillivant XR, Jornay PM)
- Non-stimulants (e.g., Strattera (atomoxetine), Intuniv (guanfacine ER), Kapvay (clonidine ER))
