You need to be careful taking
methadone with a heart condition.I would imagine that you have regular EKG's.Regular high dosing of methadone can cause problems with the QT Intervals????Anyway what you want to look at is the
duragesic patch(fentanyl).If you do decide to switch pain meds (I would stay on the methadone if you can) remember that you will not get the full benifit from the new pain killer for about a week as your receptors get used to the change over.Good luck to and hang in there.....Dave
