Buddy got it right. It's an Immediate Release. If you take it for pain you would probably end up taking it every 8-12 hours as directed by your doctor. If the Methadone is for an addiction you should only take it once. The half life of Methadone is approx: 8-59 hours so talking it once will last you 2.5 days until it exits your body through. I hope this helps a little. Have wonderful day.
