Concerta is a brand name for a long-acting form of methylphenidate, a central nervous system stimulant used primarily to treat Attention-Deficit/Hyperactivity Disorder (ADHD) in children, adolescents, and adults. It helps improve attention, focus, and impulse control by increasing the levels of dopamine and norepinephrine in the brain.

Concerta is designed as an extended-release tablet, typically taken once daily, providing symptom control for up to 12 hours. It uses a special osmotic release system to gradually deliver the medication throughout the day.

Common side effects include insomnia, loss of appetite, increased heart rate, nervousness, and headache. Concerta is a Schedule II controlled substance due to its potential for abuse, misuse, and dependence. It should only be used under the guidance of a healthcare provider, especially in individuals with a history of heart problems or mental health conditions.
