Precautions & Cautions
Long-term use or high doses of this medication may lead to tolerance, reducing its effectiveness. If you experience decreased effectiveness, contact your doctor. Do not exceed the prescribed dose.
Prior to starting this medication, your doctor may recommend heart tests. If you have questions or concerns, discuss them with your doctor.
This medication may increase the risk of seizures, particularly in individuals with a history of seizures. Consult your doctor to determine if you are at a higher risk of seizures while taking this medication.
There is a potential risk of high blood pressure associated with this medication. Monitor your blood pressure and heart rate as directed by your doctor, and seek immediate medical attention if you experience severe headaches, dizziness, fainting, or changes in vision.
To minimize potential interactions, limit your consumption of caffeine (found in tea, coffee, cola, and chocolate), as it may cause nervousness, shakiness, and rapid heartbeat when combined with this medication. Avoid consuming alcohol while taking this medication.
If you have high blood pressure, consult your doctor 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.

Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs) - concurrent use or within 14 days of MAOI discontinuation due to risk of hypertensive crisis.
Major Interactions
- Vasopressors (e.g., phenylephrine, pseudoephedrine) - risk of increased blood pressure.
- Halogenated Anesthetics (e.g., halothane, isoflurane) - risk of sudden blood pressure and heart rate increases during surgery.
- Antihypertensive drugs - may reduce the effectiveness of antihypertensive agents.

Moderate Interactions
- Coumarin anticoagulants (e.g., warfarin) - may inhibit metabolism, requiring dose adjustment of anticoagulant.
- Anticonvulsants (e.g., phenobarbital, phenytoin, primidone) - may inhibit metabolism, requiring dose adjustment of anticonvulsant.
- Tricyclic Antidepressants (e.g., imipramine, desipramine) - may inhibit metabolism, requiring dose adjustment of antidepressant.
Minor Interactions
- Alcohol - may alter release profile of extended-release formulation.
Monitoring
Baseline Monitoring
Rationale: CNS stimulants can cause increases in BP and HR.
Timing: Prior to initiation of therapy.
Rationale: Stimulants are associated with growth suppression in pediatric patients.
Timing: Prior to initiation of therapy (especially in pediatric patients).
Rationale: To identify patients at risk for cardiac events.
Timing: Prior to initiation of therapy.
Rationale: Stimulants can exacerbate pre-existing psychiatric conditions or induce new ones.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Regularly, at each visit or at least every 3-6 months.
Target: Within normal limits for age.
Action Threshold: Significant or sustained increases warrant dose reduction or discontinuation.
Frequency: Every 3-6 months (pediatric patients).
Target: Normal growth trajectory.
Action Threshold: Significant growth deceleration may warrant drug holiday or alternative treatment.
Frequency: Regularly, at each visit.
Target: Absence of new or worsening symptoms.
Action Threshold: Emergence or worsening of symptoms may require dose adjustment or discontinuation.
Frequency: Regularly, at each visit.
Target: Improved attention, reduced hyperactivity/impulsivity.
Action Threshold: Lack of efficacy or intolerable side effects may require dose adjustment or alternative treatment.
Symptom Monitoring
- Chest pain
- Shortness of breath
- Syncope
- Palpitations
- New or worsening aggression
- Hostility
- Psychotic symptoms (e.g., hallucinations, delusions)
- Manic symptoms (e.g., elevated mood, grandiosity, decreased need for sleep)
- Motor or verbal tics
- Blurred vision
- Persistent priapism
- Unexplained weight loss
- Insomnia
- Anorexia
Special Patient Groups
Pregnancy
Category C. There are no adequate and well-controlled studies in pregnant women. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Trimester-Specific Risks:
Lactation
L3 (Moderate Risk). Dexmethylphenidate and/or its metabolites are excreted in human milk. Monitor breastfed infants for agitation, insomnia, anorexia, and reduced weight gain.
Pediatric Use
Safety and effectiveness established in pediatric patients 6 to 17 years of age. Monitor growth (height and weight) regularly due to potential for growth suppression. Long-term effects on growth are not fully established.
Geriatric Use
Clinical studies did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Use with caution in elderly patients, generally starting at the low end of the dosing range, due to the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Clinical Information
Clinical Pearls
- Focalin XR is the extended-release formulation of dexmethylphenidate, providing once-daily dosing convenience.
- It is the more potent d-isomer of methylphenidate, meaning lower doses are typically used compared to racemic methylphenidate.
- Counsel patients not to crush or chew the capsules, as this will lead to immediate release of the entire dose and potential for adverse effects.
- Consider a drug holiday periodically to assess the need for continued therapy and to mitigate potential growth suppression in children.
- Careful cardiac screening is important before initiating therapy, especially in patients with pre-existing cardiac conditions or a family history of sudden cardiac death.
- Monitor for the emergence or worsening of psychiatric symptoms, including psychosis or mania, particularly in patients with a history of bipolar disorder or psychosis.
Alternative Therapies
- Methylphenidate (e.g., Ritalin, Concerta, Daytrana, Quillivant XR)
- Amphetamine/Dextroamphetamine (e.g., Adderall, Vyvanse, Dexedrine)
- Lisdexamfetamine (Vyvanse)
- Atomoxetine (Strattera)
- Guanfacine extended-release (Intuniv)
- Clonidine extended-release (Kapvay)
- Bupropion (Wellbutrin - off-label for ADHD)
