Precautions & Cautions
Before engaging in activities that require your full attention, such as driving, wait until you understand how this medication affects you. If you experience any changes in your alertness or reaction time, consult your doctor for guidance.
Long-term use or high doses of this medication can lead to tolerance, reducing its effectiveness. If you notice that the medication is not working as well as it previously did, contact your doctor. Do not exceed the prescribed dose, as this can increase the risk of adverse effects.
Prior to starting this medication, your doctor may recommend heart tests to assess your cardiovascular health. If you have any questions or concerns, discuss them with your doctor.
This medication may increase the risk of seizures, particularly in individuals with a history of seizure disorders. 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) while taking this medication, as it may cause nervousness, shakiness, and rapid heartbeat. Additionally, avoid consuming alcohol during treatment.
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.
This medication may cause changes in behavior and mood, including altered thinking, anger, and hallucinations.

Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs): Concomitant use or within 14 days of discontinuing an MAOI due to risk of hypertensive crisis.
Major Interactions
- Vasopressor Agents: May enhance the pressor effect of vasopressor agents.
- Halogenated Anesthetics: Risk of sudden blood pressure and heart rate increases during surgery.
- Serotonergic Drugs (e.g., SSRIs, SNRIs, TCAs, Triptans, Fentanyl, Tramadol, Tryptophan, St. John's Wort): Increased risk of serotonin syndrome.
- Antihypertensive Drugs: May reduce the effectiveness of drugs used to treat hypertension.
Moderate Interactions
- Alcohol: May lead to a more rapid release of dexmethylphenidate from the extended-release capsule.
- Antacids/H2 Blockers/PPIs: No significant interaction expected as release is pH-independent.
- Warfarin, Phenytoin, Phenobarbital, Primidone: May inhibit the metabolism of these drugs, requiring dose adjustment and monitoring.
Confidence Interactions
Monitoring
Baseline Monitoring
Rationale: CNS stimulants can cause increases in BP and HR.
Timing: Prior to initiation of treatment.
Rationale: CNS stimulants are associated with weight loss and growth suppression in pediatric patients.
Timing: Prior to initiation of treatment (especially in pediatric patients).
Rationale: To assess risk of psychiatric adverse events.
Timing: Prior to initiation of treatment.
Rationale: To assess risk of serious cardiovascular events.
Timing: Prior to initiation of treatment.
Routine Monitoring
Frequency: Regularly (e.g., at each visit or every 3-6 months)
Target: Within normal limits for age
Action Threshold: Persistent elevation requiring intervention or dose adjustment.
Frequency: Regularly (e.g., every 3 months for pediatric patients)
Target: Normal growth trajectory
Action Threshold: Significant growth deceleration or weight loss.
Frequency: Regularly (at each visit)
Target: Stable or improved
Action Threshold: New or worsening symptoms requiring intervention or discontinuation.
Frequency: Regularly (at each visit)

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. Studies in animals have shown adverse effects.
Trimester-Specific Risks:
Lactation
L3 (Moderately Safe). Dexmethylphenidate and/or its metabolites are excreted in human milk. The American Academy of Pediatrics considers methylphenidate (racemic mixture) to be compatible with breastfeeding. Monitor breastfed infants for agitation, insomnia, anorexia, or poor weight gain.
Pediatric Use
Approved for children 6 years and older. Monitor growth (height and weight) and cardiovascular parameters. Assess for emergence or worsening of psychiatric symptoms. Long-term safety and efficacy in children under 6 years have not been established.
Geriatric Use
Safety and efficacy have not been established in geriatric patients. Use with caution due to potential for increased sensitivity to stimulant effects, especially cardiovascular effects. Consider lower initial doses and careful titration.
Clinical Information
Clinical Pearls
- Focalin XR is the d-threo-enantiomer of methylphenidate, meaning it's the more active component, allowing for lower doses compared to racemic methylphenidate.
- The extended-release formulation provides a biphasic release, aiming for once-daily dosing and sustained effect throughout the school/work day.
- Patients should be advised to take Focalin XR in the morning to avoid insomnia.
- Due to its Schedule II classification, strict prescribing regulations apply, including no refills and specific prescription requirements.
- Careful monitoring for cardiovascular and psychiatric adverse effects is crucial, especially during dose titration and long-term therapy.
- Patients and caregivers should be educated on the potential for abuse and diversion.
Alternative Therapies
- Methylphenidate (e.g., Ritalin, Concerta, Daytrana, Quillivant XR)
- Amphetamine/Dextroamphetamine (e.g., Adderall, Vyvanse, Dexedrine)
- Lisdexamfetamine (Vyvanse)
- Atomoxetine (Strattera) - non-stimulant
- Guanfacine extended-release (Intuniv) - non-stimulant
- Clonidine extended-release (Kapvay) - non-stimulant
- Behavioral therapy for ADHD
