I’m hoping someone can answer this for me as well. I took one pill at 4-5am. It’s now 9:30 pm almost. Would I be ok drinking a glass or two of wine?

So I had to take this last week for 7 days and was advised not to drink any alcohol for the entire period including another 48-72 hours after finishing the prescription. I had an event during that time that I've been planning for months including making a mimosa bar, jello shots, etc. So I tested it out each day to see if i would get sick. I never once had anything happen to me. I drank heavily even. However, I do not recommend trying it simply because every person reacts differently to medication and i myself am a pretty heavy drinker on a regular basis which is most likely why it didn't affect me.

I drank while on this medication before, no effects. This last time, I was violently throwing up for days, had to have an IV.
5 days later and I'm still not 100%, not even close.

I'd say, avoid at all costs.

I've taken this medicine a couple times and drank like a sailor . Nothing happened besides a normal hangover and face turned more red than normal but nothing crazy. Everybody reacts different though .

I waited 36 hours after my last dose to have a drink and had zero side effects. I've also been on it before this past round and had a few drinks just about 12 hours after my last dose and been completely fine. With that being said, I do drink quite a bit and was only on a small dose of Metro so I am sure both of those were factors that helped me avoid consequences. I have read so many horror stories though, so if I hadn't already known how it would affect me before I even knew you weren't supposed to drink within 72 hours of your last dose, I wouldn't have taken the risk.

I made an account just to say this - current research does not have evidence that metronidazole has an Antabuse like reaction. There is a group of people who do have a rx so you are taking a risk - do your research and make your own choice.

I’ve had a glass of wine or two for several days during my course and had no issues. I’ve been on this medication multiple times and have stopped a dose to drink as well but I’m not sure if that could lead to antibiotic resistance or giving the bad bacteria more time to grow back.. obviously taking the antibiotic as directed would be the risk free option but I wanted to make my experience known.

Half life of metronidazole is 6-12 hours, I’m not sure if it accumulates in the system but that leads me to believe in 24 hours you could be sure it’s gone. Hope this helps!

I can't speak for bacterial vagionosis -I'm taking mine for a skin infection on my face resulting from a tooth abcess- but I've had no major side effects from drinking on these meds. The alcohol is hitting me a little harder than usual, and the hangover is worse than normal, but there are no serious side effects. That said, I wouldn't want to endorse it because it goes against medical advice, but I would like to reassure you that a couple of drinks won't do any harm.

Avoid alcoholic beverages while taking this medication and for at least 1 day (3 days if you are taking the oral capsules) after finishing this medicine because drinking alcohol may result in severe stomach upset/cramps, nausea, vomiting, headache and flushing. You will get really nasty sick if you drink while taking this medication-not might , WILL!

I have really tried not to answer you because I have a strong reaction to people who have to drink when on meds, but I have to do it. It is NEVER advisable to drink when on medication, but with this med you can get abdominal cramps, nausea, vomiting and headache. Its best not to drink for at least a day after you stop it too.
