About Concerta 18mg
Concerta® 18mg is the starting dose extended-release methylphenidate tablet by Janssen. The red capsule-shaped tablet with imprint alza 18 uses the patented OROS® (Osmotic Release Oral System) delivery mechanism, which releases medication gradually using osmotic pressure — providing 10–12 hours of consistent ADHD coverage from a single daily dose.
The OROS system delivers 22% of the dose immediately upon ingestion and 78% via the pump mechanism throughout the day, mimicking a three-times-daily IR methylphenidate dosing pattern.
Dosage
Children 6+: 18mg once daily in the morning. Adults: 18–72mg/day. Swallow whole — do not crush or chew. Prescription required.
