Adderall XR, a widely prescribed medication for Attention Deficit Hyperactivity Disorder (ADHD), has become a staple in the treatment of this condition. One of the most common questions among patients and caregivers is how long the effects of 15mg XR Adderall last. This article aims to provide a detailed and informative response, exploring the factors that influence the duration of action and what patients can expect from their treatment.
Introduction to Adderall XR
Adderall XR is an extended-release formulation of the medication, designed to provide a steady and controlled release of the active ingredients, amphetamine and dextroamphetamine. This allows for once-daily dosing, which can improve adherence to treatment and reduce the risk of side effects. The 15mg dose is a common starting point for many patients, and its duration of action can vary depending on several factors.
