Short acting: In clinical experience, metadate never exhibits effectiveness beyond 4-6 hours. Methylphenidate has a very short half life. About 90 minutes. The prolonged duration mechanism in metadate prolongs the duration a bit. But two doses are usually necessary to cover an entire day. Check with your prescribing doctor for titration of your medication.
