Overview

ℹ️

What is this medicine?

Dexmethylphenidate ER is a medication used to treat Attention Deficit Hyperactivity Disorder (ADHD). It's a stimulant that works by affecting certain natural chemicals in the brain to help improve attention, focus, and control impulsive behavior. The 'ER' means extended-release, so it works throughout the day with one dose.

How to Use This Medicine

Taking Your Medication

To use this medication correctly, follow your doctor's instructions and read all the information provided. Take your medication as directed, with or without food. However, note that taking it with food may delay its onset of action. To minimize sleep disturbances, take your medication early in the day.

It's essential to swallow the medication whole; do not chew or crush it. If you have difficulty swallowing the medication whole, you can sprinkle its contents onto applesauce. If you choose this method, swallow the mixture immediately without chewing.

Storing and Disposing of Your Medication

Store your medication at room temperature, protected from light and moisture. Avoid storing it in a bathroom. Keep your medication in a secure location where children cannot see or access it, and where others cannot easily obtain it. Consider using a locked box or area to ensure its safety. Remember to keep all medications out of reach of pets.

Missing a Dose

If you miss a dose, skip it and resume your regular dosing schedule. Do not take two doses at the same time or take extra doses to make up for the missed one.
πŸ’‘

Lifestyle & Tips

  • Take exactly as prescribed, usually once daily in the morning to avoid sleep problems.
  • Do not crush, chew, or divide the capsule. Swallow whole or sprinkle contents on a small amount of applesauce and consume immediately.

Pharmacology

πŸ”¬

Mechanism of Action

Dexmethylphenidate is the d-threo enantiomer of methylphenidate. It is a central nervous system (CNS) stimulant. Its therapeutic effect in Attention Deficit Hyperactivity Disorder (ADHD) is thought to be due to its ability to block the reuptake of norepinephrine and dopamine into the presynaptic neuron and increase the release of these monoamines into the extraneuronal space.

Tmax: Biphasic: approximately 1.5 hours and 4.5 hours (for ER formulation)
FoodEffect: Food (high-fat meal) can delay Tmax by approximately 1.5 hours but does not significantly affect AUC or Cmax.

Distribution:

Vd: Approximately 2.6 L/kg
ProteinBinding: Approximately 15%
CnssPenetration: Yes

Elimination:

HalfLife: Approximately 5-7 hours (for ER formulation)
Clearance: Not readily available for dexmethylphenidate specifically, but methylphenidate clearance is high.
ExcretionRoute: Primarily renal (approximately 90% as ritalinic acid)
Unchanged: <1%

Pharmacodynamics

OnsetOfAction: Approximately 1-2 hours
PeakEffect: Biphasic: approximately 1.5 hours and 4.5 hours

⚠️

Precautions & Cautions

It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication. This will help ensure your safety and prevent any potential interactions with other treatments.

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.

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:

First Trimester: Potential increased risk of cardiac malformations (based on methylphenidate data), though absolute risk is low.
Second Trimester: Limited data, potential for fetal growth restriction.
Third Trimester: Limited data, potential for withdrawal symptoms in neonate if exposed near term.
🀱

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 mother’s clinical need for dexmethylphenidate and any potential adverse effects on the breastfed infant.

Infant Risk: Low to moderate risk. Monitor for irritability, poor feeding, and sleep disturbances.
πŸ‘Ά

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.

πŸ‘΄

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

πŸ’Ž

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.
πŸ”„

Alternative Therapies

  • Methylphenidate (various formulations: immediate-release, extended-release, transdermal patch, chewable tablets)
  • Amphetamine/dextroamphetamine (various formulations: Adderall, Vyvanse, Mydayis)
  • Lisdexamfetamine (Vyvanse)
  • Atomoxetine (Strattera) - non-stimulant
  • Guanfacine extended-release (Intuniv) - non-stimulant
  • Clonidine extended-release (Kapvay) - non-stimulant

Cost & Coverage

Average Cost: Varies widely, e.g., $150-$400 per 30 capsules
Generic Available: Yes
Insurance Coverage: Tier 2 or Tier 3 (for brand, generic often Tier 1)
