There's a long list of narcotics ranging from Tylenol w/codeine to Vicodin, Percocet, oxyodone, morphine, Dilaudid, Fentanyl patches and methadone and
more. Those drugs are often used in long and/or short-acting form. I was put on Clonidine years ago, which is an old blood pressure med. There are thoughts it can help nerve pain and also withdrawal. It hasn't helped my nerve pain, I don't think, but I stay on it as my blood pressure can run high and pain makes it go higher.
