A BOTTLE OF 30 8MG GOES FOR AROUND 350 IN MY STATE. Of course,you can buy generic for far, far less under the name Buprenorphine.
I have insurance, so SUBOXONE is 80 a month, bupe is $5....big diff. If money is a problem, i believe GENERIC low dose is the way to go. But the doctor visits will be costly. AND, at least at first you will have to go every month to a visit, in order to get a refill. I get mine from a psychiatrist, who DOESN'T take insurance (none do) so in reality, though i pay 5 for the meds, I pay another 175 per month for a 45 minute visit.
Good luck, mam, having a child with a habit is an awful, awful thing....and please try to remember that THIS problem is one that is often better handled with tough love, as much as it hurts. I know from experience. THank god my wife can use the tough love routine, I know I couldn't ,, and I would have made things worse.
