Adderall and Concerta are prescription stimulants commonly used to treat ADHD, but they differ in formulation, duration, and effect. Adderall combines amphetamine salts and typically lasts 4–6 hours (IR) or up to 12 hours (XR), while Concerta contains methylphenidate and provides extended symptom control for up to 12 hours. Comparing Adderall vs Concerta helps patients and caregivers understand which option may best fit individual needs based on effectiveness, side effects, and lifestyle considerations.
