Precautions & Cautions
When you first start taking this medication, be cautious when driving or performing tasks that require alertness and clear vision, as it may affect your ability to do so. Wait until you understand how this medication affects you before engaging in these activities.
Long-term or high-dose use of this medication can lead to tolerance, where the medication becomes less effective, and you may need higher doses to achieve the same effect. If you notice that the medication is not working as well as it used to, contact your doctor. Do not take more than the prescribed dose, as this can lead to adverse effects.
Prolonged or regular use of this medication may cause dependence, and stopping it abruptly can result in withdrawal symptoms. If you need to reduce the dose or stop taking this medication, consult your doctor, and follow their instructions carefully. Report any adverse effects to your doctor promptly.
Before starting this medication, you may need to undergo heart tests to ensure your safety. If you have any questions or concerns, discuss them with your doctor.
This medication may cause an increase in blood pressure. Monitor your blood pressure and heart rate as directed by your doctor, and have regular blood tests to check for any potential effects.
It is crucial to inform all your healthcare providers and laboratory personnel that you are taking this medication, as it may affect the results of certain lab tests. Do not take antacids while taking this medication, as they may interact with it.
Some individuals may experience behavioral or mood changes, such as altered thinking, anger, or hallucinations, while taking this medication. If you or a family member have a history of mental or mood disorders, such as depression or bipolar illness, or if a family member has committed suicide, inform your doctor.

- Methylene Blue (MAOI activity)
Major Interactions
- Serotonergic drugs (SSRIs, SNRIs, TCAs, triptans, fentanyl, lithium, tramadol, St. John's Wort) - risk of serotonin syndrome
- Antihypertensives - may reduce hypotensive effect
- Urinary alkalinizing agents (e.g., sodium bicarbonate, acetazolamide, thiazide diuretics) - increase amphetamine levels and prolong half-life
- Urinary acidifying agents (e.g., ammonium chloride, ascorbic acid) - decrease amphetamine levels and shorten half-life

- Antipsychotics (e.g., phenothiazines, haloperidol) - may antagonize stimulant effects
Moderate Interactions
- Proton Pump Inhibitors (PPIs) and H2 blockers - may alter absorption (less significant for ER formulation)
- CYP2D6 inhibitors (e.g., quinidine, fluoxetine, paroxetine, ritonavir) - may increase amphetamine exposure

Minor Interactions
- Not available
Monitoring
Baseline Monitoring
Rationale: Risk of cardiovascular adverse events (hypertension, tachycardia)
Timing: Prior to initiation
Rationale: Risk of growth suppression in pediatric patients; general health assessment
Timing: Prior to initiation
Rationale: Risk of exacerbating pre-existing psychiatric conditions or inducing new ones
Timing: Prior to initiation
Rationale: Risk of serious cardiovascular events
Timing: Prior to initiation
Routine Monitoring
Frequency: At each visit or at least every 3-6 months
Target: Within normal limits for age/baseline
Action Threshold: Sustained elevation (e.g., >95th percentile for age/sex/height or significant increase from baseline) warrants investigation/intervention.
Frequency: Every 3-6 months (pediatric); annually (adult)
Target: Normal growth trajectory (pediatric); stable weight (adult)
Action Threshold: Significant growth deceleration or weight loss warrants investigation/intervention.
Frequency: At each visit
Target: Absence of new or worsening symptoms
Action Threshold: Emergence or worsening of symptoms warrants dose adjustment or discontinuation.
Frequency: At each visit
Target: Improved attention, reduced hyperactivity/impulsivity, improved academic/social functioning
Action Threshold: Lack of efficacy or worsening symptoms warrants dose adjustment or re-evaluation of diagnosis/treatment plan.
Symptom Monitoring
- Chest pain
- Shortness of breath
- Syncope
- Palpitations
- New or worsening aggression
- Hallucinations
- Delusions
- Mania
- Tics
- Unexplained weight loss
- Sleep disturbances

Special Patient Groups
Pregnancy
Generally not recommended during pregnancy unless the potential benefit justifies the potential risk to the fetus. Amphetamines cross the placenta.
Trimester-Specific Risks:
Lactation
Amphetamines are excreted into breast milk. Due to the potential for serious adverse reactions in breastfed infants (e.g., irritability, poor feeding, sleep disturbances, growth suppression, cardiovascular effects), breastfeeding is not recommended during treatment.
Pediatric Use
Approved for ADHD in children 6 years and older. Monitor growth (height and weight) carefully. Risk of growth suppression. Monitor for emergence or worsening of psychiatric symptoms (e.g., psychosis, mania, tics).
Geriatric Use
Use with caution in elderly patients, generally not recommended due to increased risk of cardiovascular adverse events and other comorbidities. Start with lower doses and titrate slowly. Monitor cardiovascular status closely.
Clinical Information
Clinical Pearls
- Adderall XR has a bimodal release profile, providing two peaks of plasma concentration, which contributes to its extended duration of action.
- The capsule can be opened and sprinkled on applesauce for patients who have difficulty swallowing, but the beads should not be chewed.
- Patients should avoid taking doses in the late afternoon or evening to prevent insomnia.
- Regular monitoring of blood pressure, heart rate, and growth (in children) is crucial.
- Educate patients and caregivers about the high abuse potential and the importance of secure storage.
- Consider a 'drug holiday' (e.g., weekends or school breaks) for pediatric patients to assess baseline ADHD symptoms and potentially mitigate growth suppression, though this practice is debated and should be discussed with a physician.
Alternative Therapies
- Methylphenidate (e.g., Concerta, Ritalin LA, Focalin XR)
- Non-stimulants (e.g., Atomoxetine, Guanfacine ER, Clonidine ER)
- Behavioral therapy
