Clinical trials have shown that participants who completed a 12-week treatment program that included 50 mg of Naltrexone and counseling saw significant improvements. Of the 54% of participants who completed the program, 39% abstained from alcohol by the end of the program. Within the same group, 86% of participants who continued drinking while taking Naltrexone consumed less alcohol after 12 weeks. This is to say that people who stick with their program experience promising success rates. That means consistently taking Naltrexone before drinking and attending counseling or coaching sessions.
