Precautions & Cautions
Until you know how this medication affects you, avoid driving and other activities that require you to be alert. If you have been taking this medication for an extended period or at high doses, you may develop tolerance, which means it may not work as well as it initially did. In this case, you may need higher doses to achieve the same effect. If you suspect you have developed tolerance, contact your doctor. Do not exceed the prescribed dose.
Before starting this medication, your doctor may recommend heart tests to ensure your safety. 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 seizures. Consult your doctor to determine if you are at a higher risk of seizures while taking this medication.
There is a 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 headache, 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 may cause nervousness, shakiness, and rapid heartbeat. Additionally, avoid consuming alcohol while on this medication.
If you have high blood pressure, consult your doctor before taking any 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. If you or a family member have a history of mental or mood problems, such as depression or bipolar disorder, or if a family member has committed suicide, inform your doctor. Seek immediate medical attention if you experience hallucinations, changes in behavior, or signs of mood changes, including 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 weigh the 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)
Major Interactions
- Vasopressor agents (e.g., phenylephrine, pseudoephedrine): Risk of hypertensive crisis.

Monitoring
Baseline Monitoring
Rationale: To identify pre-existing cardiovascular conditions that may be exacerbated by stimulant use.
Timing: Prior to initiation of therapy
Rationale: To establish baseline for monitoring growth in pediatric patients.
Timing: Prior to initiation of therapy
Rationale: To assess risk for psychiatric adverse events (e.g., psychosis, mania).
Timing: Prior to initiation of therapy
Routine Monitoring
Frequency: At each visit or every 3-6 months
Target: Within normal limits for age
Action Threshold: Significant or sustained elevations warrant dose reduction or discontinuation.
Frequency: Every 3-6 months
Target: Normal growth trajectory
Action Threshold: Significant growth deceleration or weight loss may require dose adjustment or drug holiday.
Frequency: At each visit
Target: Absence of new or worsening symptoms
Action Threshold: Emergence of new psychotic or manic symptoms warrants immediate evaluation and discontinuation.
Frequency: At each visit
Target: Improved attention, reduced hyperactivity/impulsivity, improved academic/social functioning
Action Threshold: Lack of efficacy or worsening symptoms may require dose adjustment or alternative therapy.
Symptom Monitoring
- Chest pain
- Shortness of breath
- Syncope
- Palpitations
- New or worsening aggression
- New psychotic symptoms (e.g., hallucinations, delusions)
- Manic symptoms (e.g., elevated mood, decreased need for sleep, racing thoughts)

- Unexplained weight loss
- Growth deceleration (in children)
- Priapism (prolonged and painful erections)
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. Data from a pregnancy registry suggest an increased risk of cardiac malformations with methylphenidate exposure in the first trimester, but overall risk is low.
Trimester-Specific Risks:
Lactation
Dexmethylphenidate and/or its metabolites are excreted into human milk. Monitor breastfed infants for signs of adverse reactions (e.g., agitation, insomnia, decreased weight gain). Weigh the developmental and health benefits of breastfeeding against the motherβs clinical need for dexmethylphenidate and any potential adverse effects on the breastfed infant.
Pediatric Use
Safety and efficacy established in pediatric patients 6 to 17 years of age. Monitor growth (height and weight) regularly, as long-term use may be associated with growth suppression. Monitor for emergence or worsening of psychiatric symptoms.
Geriatric Use
Safety and efficacy have not been established in geriatric patients. Use with caution due to potential for increased sensitivity to adverse effects, particularly cardiovascular effects, and presence of comorbidities.
Clinical Information
Clinical Pearls
- Administer in the morning to minimize the risk of insomnia.
- Capsules can be opened and sprinkled on applesauce for patients who have difficulty swallowing whole capsules, but the mixture should be consumed immediately.
- Monitor for signs of diversion or abuse, especially in patients with a history of substance abuse.
- Consider drug holidays (e.g., weekends, school breaks) in pediatric patients to assess continued need for medication and potentially mitigate growth suppression, though this should be discussed with a healthcare provider.
- Patients should be advised to avoid activities requiring mental alertness, such as driving or operating machinery, until they know how the medication affects them.
Alternative Therapies
- Methylphenidate (various formulations: immediate-release, extended-release, transdermal patch, chewable tablets)

- Lisdexamfetamine (Vyvanse)
- Atomoxetine (Strattera) - non-stimulant
