Precautions & Cautions
Before operating a vehicle or engaging in activities that require your full attention, wait until you understand how this medication affects you. This is crucial to prevent accidents and ensure your safety.
Long-term use or high doses of this medication can lead to tolerance, which means it may not work as effectively, 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.
Before 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 medical attention immediately if you experience severe headaches, dizziness, fainting, or changes in vision.
To minimize potential side effects, limit your consumption of caffeine (found in tea, coffee, cola, and chocolate) while taking this medication, as it can 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 and 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. If you or a family member have a history of mental health conditions, such as depression or bipolar disorder, or if a family member has committed suicide, inform your doctor. Seek medical attention immediately if you experience hallucinations, changes in behavior, or signs of mood changes, such as depression, suicidal thoughts, nervousness, emotional instability, abnormal thinking, anxiety, or loss of interest in life.
In some cases, this medication may affect growth in children and adolescents. Regular growth checks may be necessary, so discuss this with your doctor.
If you are pregnant, plan to become pregnant, or are breastfeeding, consult your doctor to discuss the potential benefits and risks of this medication to you and your baby.

Drug Interactions
Contraindicated Interactions
- Monoamine Oxidase Inhibitors (MAOIs) - concurrent use or within 14 days of MAOI discontinuation (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.
- Serotonergic Drugs (e.g., SSRIs, SNRIs, TCAs, triptans, fentanyl, lithium, tramadol, St. John's Wort) - theoretical risk of serotonin syndrome, though less pronounced than with other stimulants.
Moderate Interactions
- Antihypertensive Drugs (e.g., ACE inhibitors, beta-blockers) - may reduce the effectiveness of antihypertensives.
- Coumarin Anticoagulants (e.g., warfarin) - may prolong prothrombin time (monitor INR).
- Anticonvulsants (e.g., phenobarbital, phenytoin, primidone) - may inhibit metabolism of these drugs, increasing serum concentrations.
- Tricyclic Antidepressants (TCAs) - may increase plasma concentrations of TCAs.
Minor Interactions
- Alcohol - may alter the release profile of the extended-release formulation.

Special Patient Groups
Pregnancy
Use during pregnancy should be avoided unless the potential benefit justifies the potential risk to the fetus. Limited data suggest a possible association with cardiac malformations and other congenital anomalies with methylphenidate exposure during the first trimester.
Trimester-Specific Risks:
Lactation
Dexmethylphenidate is excreted into breast milk. Due to the potential for serious adverse reactions in breastfed infants (e.g., agitation, insomnia, reduced weight gain), 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.
Pediatric Use
Approved for children 6 years and older. Monitor growth (height and weight) carefully. Long-term effects on growth are a concern. Psychiatric adverse events (e.g., psychosis, mania) can occur.
Geriatric Use
Safety and efficacy have not been established in geriatric patients. Use with caution due to potential for increased sensitivity to stimulant effects (e.g., cardiovascular effects, anxiety, insomnia). Generally not recommended for this population unless compelling reasons and close monitoring.
Clinical Information
Clinical Pearls
- Focalin XR is the d-isomer of methylphenidate, meaning it is the more pharmacologically active enantiomer, allowing for lower doses compared to racemic methylphenidate.
- Administer once daily in the morning to avoid insomnia.
- Capsules can be opened and sprinkled on applesauce for patients who have difficulty swallowing, but the beads should not be chewed.
- Monitor blood pressure and heart rate regularly, especially in patients with pre-existing cardiovascular conditions.
- Be aware of the potential for growth suppression in pediatric patients; consider drug holidays if growth deceleration is significant.
- Educate patients and caregivers about the potential for abuse and dependence, and the importance of secure storage.
- Assess for underlying psychiatric conditions (e.g., bipolar disorder, psychosis) before initiating treatment, as stimulants can exacerbate these conditions.
Alternative Therapies
- Methylphenidate (e.g., Ritalin, Concerta, Daytrana, Quillivant XR)
- Amphetamine/Dextroamphetamine (e.g., Adderall, Vyvanse, Dexedrine)
- Lisdexamfetamine (Vyvanse)
- Atomoxetine (Strattera) - non-stimulant
- Guanfacine ER (Intuniv) - non-stimulant
- Clonidine ER (Kapvay) - non-stimulant
- Behavioral therapy for ADHD
