What is Methylphenidate XR? Learn about its uses for ADHD, dosage forms, how to take it, who should avoid it, cost, and more in this 2026 guide.
Methylphenidate XR is an extended-release prescription stimulant medication used to treat attention-deficit/hyperactivity disorder (ADHD) in children aged 6 and older, adolescents, and adults.
If you or someone in your family has been prescribed Methylphenidate XR — or you're researching it before talking to your doctor — this guide covers the basics: what it is, what it treats, how to take it, who should avoid it, and what it costs in 2026.
Methylphenidate XR is the extended-release version of methylphenidate hydrochloride, a central nervous system (CNS) stimulant that's been used to treat ADHD since the 1950s. The "XR" (or "ER") means it's designed to release the medication slowly throughout the day, so you only need to take it once instead of multiple times.
Methylphenidate XR is sold under several brand names, each with a slightly different release mechanism:
Generic versions are widely available and are the same active ingredient at a lower cost.
Methylphenidate XR belongs to the CNS stimulant drug class. It's classified as a Schedule II controlled substance by the DEA, which means it has recognized medical uses but also a high potential for abuse and dependence. This classification affects how it's prescribed — you'll typically need a new prescription each month (no automatic refills).
Methylphenidate XR is FDA-approved to treat ADHD in children (age 6+), adolescents, and adults. ADHD is a neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with daily functioning.
Immediate-release formulations of methylphenidate are also approved for narcolepsy, but the extended-release versions are primarily used for ADHD.
Some doctors prescribe methylphenidate off-label for conditions like treatment-resistant depression (as an add-on therapy), cancer-related fatigue, and cognitive issues after traumatic brain injury. These are not FDA-approved uses.
The specifics depend on which formulation you're prescribed, but here are the general guidelines:
Important: Do not drink alcohol while taking Methylphenidate XR. Alcohol can cause "dose dumping" — where the entire dose releases at once instead of slowly — which can lead to dangerous side effects.
Your doctor will typically start you at a low dose and increase gradually until the right balance of symptom control and side effects is found. For a deeper look at how the medication works in your body, see our article on how Methylphenidate XR works.
Methylphenidate XR is not safe for everyone. You should not take it if you have:
