Concerta vs Ritalin
Understanding the differences between these methylphenidate medications
The Bottom Line
Concerta and Ritalin contain the same active ingredient — methylphenidate. The main difference is the duration of action. Concerta is extended-release (lasts 10-12 hours), while Ritalin IR is short-acting (lasts 3-4 hours).

Concerta (Extended-Release)
How It Works
Concerta uses OROS® technology — an osmotic pump system that releases methylphenidate gradually throughout the day. About 22% releases immediately, with the rest releasing slowly over 10-12 hours.
Pros
Cons
Ritalin IR (Immediate-Release)
How It Works
Ritalin IR releases all its methylphenidate at once, producing a quick onset but shorter duration. It's the oldest formulation of methylphenidate and remains widely used.
