For Alcohol Use Disorder "My boyfriend has been on Antabuse for a few months now, and for the most part, just the thought of drinking scared him. He takes this pill daily at the same time. Now, after witnessing one of the sickest people I've ever seen due to one drink while taking this medicine, I'm scared for him. He literally was bright red, his body was on fire, and the sickness he felt was something he had never felt before and never wishes that he had drunk. He was in massive pain. This drug works wonders, but under no circumstances, no matter how much stress you have in your life, DON'T DRINK while on this medicine. You have absolute helplessness over the situation. There isn't an antidote."

For Alcohol Use Disorder "So, I've been battling alcoholism for years - about a decade (and I'm 30). I've been to 2 treatment centers and an outpatient program with the longest stint of sobriety being a solid 109 days. I've gone from being 100% alcohol dependent in my mid-20s to sober to recreational drinking, but almost always I'll end up on benders or sneaking it. Anyway, I tried Antabuse about 6 months ago and took it for about a month... drank on it repeatedly and got so sick each and every time, so I just stopped taking the pills. I'm talking beet red face and neck and chest, heart racing, etc. I'm back on it now. I started yesterday and vowed to take it for 6 months."

For Alcohol Use Disorder "Antabuse works! It really helped me stay sober for 3 months. I didn't even think about drinking because I just knew it wasn't an option. Well, a few days ago I drank 3 light beers. I was violently sick! I threw up 3 times and couldn't even hold water in my system. I'm glad it happened because I will never drink again as long as I'm taking Antabuse."

"I have tried this medication without success. When my cravings became too difficult, I would stop taking the medication and plan my drinking for 4 to 5 days later, which sometimes wasn't enough time to get the medicines out of my system and I became very ill. My recommendation is if you are going to use this medication and you don't trust yourself, have someone else administer the pills to you and keep you accountable. Congratulations to those who have found success with this. I'm trying Campral next."

For Alcohol Use Disorder "I tried Antabuse, the first time I drank on it, I was sick, but after 48 hours, it did nothing but make my heart beat fast. You have to take it every day for the best results."
