Seems you have apprehensions about Methadone, I have been well educated on Methadone. I know more than my Medical doctor, she didn't prescribe Methadone, my Pain Management Doctor did. Also my Mother & Sister are both Registered Nurses, I just stayed out of the medical field. They both work for a very well known clinic that deals with Opiate addiction, Methadone done works very well for that addiction. I just have seen in people that taking Amitriptyline can cause suicidal tendencies. Thank you for your response. Sometimes, I have seen my pharmacist doesn't catch everything, he fills my prescription for Methadone every month, but never says anything about my allergy for codeine & morphine, so he doesn't catch everything! My pain management doctor knows about the allergy & taking Methadone hasn't caused an allergy reactions, my pharmacist didn't even ask!
