I was on Methadone for chronic pain,but had severe allergic reactions,took 6 months and several E.R trips to get some help.I finally found a new doc and she had me drop from 36mg of methadone for 3 days and take 10 mg oxycodone every 12 hours for 3 days and then drop to 15 mg of methadone for 3 days and take 10 mg of the oxycodone for every 6 hours well now iam off of the methadone and am taking 30 mg of oxycodone every 6 hours but iam not getting any relief.How long does it take the methadone to get out of your system to feel the effects of the other narcotic? Still having some withdrawls but not as bad as if i had nothing but i feel like iam just taking tylenol,not that iam looking for the high,but i feel like the methadone is still blocking it,is this possible?
