Key takeaways
Dexmethylphenidate (Focalin, Focalin XR) and clonidine ER (Kapvay) are both used to treat attention-deficit hyperactivity disorder (ADHD), but they work in different ways and belong to different medication classes. Dexmethylphenidate is a stimulant that helps improve focus and attention by increasing levels of norepinephrine and dopamine in the brain. In contrast, clonidine ER is an alpha-2 adrenergic agonist that works on certain brain receptors, though its exact mechanism for treating ADHD is not well understood. Dexmethylphenidate is a controlled substance with a risk of misuse and dependence, while clonidine ER is not a controlled substance and has no potential for abuse. Dexmethylphenidate can cause side effects like stomach upset, nervousness, and trouble sleeping, whereas clonidine ER often causes irritability, nausea, and sleepiness. Additionally, dexmethylphenidate is available in both immediate-release and extended-release forms, while clonidine ER is only available as an extended-release tablet. Both medications are available in generic forms, making them more affordable options.
