Has anyone had any experience with the new opiate blocker vivitrol? It's a once a month injection that's supposed to better at suppressing the cravings from opiates? More curious if it works as my sons insurance doesn't cover it and it will be $1200 for 1 injection. Why is the medical field so far behind? Every family member how has an addict know 28 days in rehab doesn't even begin to help a herion addict and finding a year long program that insurance covers doesn't exist. At least my son can't find 1.....the longest help he had was being in jail for 9 months and then a drug court system for the next year but once he was done with that he went right back to herion. 9 years of active use and no hope in site....he's tried methodone(awful awful stuff) suboxone (not much better)
