Has the company EVER said this injectable is a sure? NO!! Obviously you did not read the company news.
"Alkermes has said that administering doses monthly should help alcoholics stay sober as it relieves them of the burden of having to decide daily whether to take the medication.
Vivitrol is to be used in conjunction with traditional addiction counseling."
I don't think it was ever "hyped" as a cure, at least not by ALKS itself. The published research reports (I think published on their site) indicate substantial reductions in the number of binge days for those taking Vivitrol. Although they didn't provide individual data, it seems like some patients benefitted greatly, some a bit, and some not at all. This variability is quite typical for any psychoactive drug. But overall, on average, it made a big difference. No one claimed it was "a cure" that I'm aware of.
