Dexmethylphenidate
Generic: dexmethylphenidate hydrochloride · Brand: Focalin® / Focalin XR® · Class: Stimulant — Schedule II (Methylphenidate)
🧠
How It Works
Dexmethylphenidate is the active d-enantiomer of methylphenidate — essentially the more active half of the Ritalin molecule. By isolating only the therapeutically active component, the same ADHD benefit can be achieved at approximately half the dose of methylphenidate. This may result in fewer side effects for some patients while maintaining equivalent effectiveness. Like methylphenidate, it blocks dopamine and norepinephrine reuptake. Available in immediate-release (Focalin) and extended-release (Focalin XR) formulations.

Cardiovascular Risk: Stimulants raise heart rate and blood pressure. Tell your provider about any heart conditions, high blood pressure, or family history of heart problems. Seek emergency care for chest pain, shortness of breath, or fainting.
Psychiatric Effects: Stimulants can cause or worsen anxiety, irritability, agitation, or psychosis — especially at higher doses. Report any new or worsening psychiatric symptoms.
Growth in Children: Stimulants can slow height and weight gain in children. Your provider will monitor growth at each visit.
Do Not Use With MAOIs: Combining stimulants with MAOIs can cause a dangerous, potentially life-threatening reaction. Wait at least 14 days after stopping an MAOI.
