Revia and morphine?

Question

I was given revia for alcoholism a few months ago and stopped taking it and still havent drank, and then took one pill and a few days later ate half a fetanyl patch and felt nothing. Now its two days later and i took 60 mg morphine and I STILL dont feel opiate effects...anyone know how long this will last? I took the last pill about 3 days ago.

P.S please don't ***** about me using opiates, it's my choice.

Answer 1

Its half life is 13 hours so I guess 5 half lives = ~72 hours is its washout period. So if you now take a morphine product you'd wanna take a low dose as the naltrexone was allowing you survive quite high doses..........you might get respiratory depression so be careful
