Alcohol and metronidazole interact in a severe or even dangerous way. Even the prescribing information for metronidazole products warn of this possible interaction, stating that consuming alcohol while taking this drug (or even within three days of metronidazole) may cause the following side effects: Nausea; Vomiting; Flushing; Headache; Digestive upset.
However, recent clinical studies have failed to demonstrate a significant interaction between metronidazole and alcohol. Despite the lack of a demonstrated interaction, the doc/pharmacist will probably still warn you to avoid alcohol while taking this medicine. Most of the supposed effects of the metronidazole/alcohol interaction can be attributed to just the antibiotic.
Please take care, best wishes!

Rajive sent you the drug interaction info and he is very thorough. Let me put it to you in plain everyday language, you will hurl, and hurl and hurl. Do NOT attempt to take metro/flagyl until at least 48 hours have passed. It has that warning on the bottle for a very good reason. It can actually make evn people who don't drink alcohol hurl if they take it on an empty stomach. Mkr sure you eat before you take this medicine. Patti

Hello yellibelli - So after all of these thorough and complete answers... DO NOT START YOUR MEDICATION FOR A FEW DAYS!!! That is the bottom line. You said you had some alcohol 11 hours ago now. I would wait until Friday to start that medication or even Saturday but there is NO DRINKING while taking this medication and when the 7 days is up... you MUST WAIT ANOTHER 48 HOURS TO DRINK!
This just cannot be overstated enough as far as I am concerned. NO DRINKING or you will be sicker than dog during a dog day afternoon!!! Okay???
NO BOOZE OF ANY KIND... NONE... NODDA... NIEN. Be careful what you eat and know what is in the food you eat. NO ALCOHOL IN SAUCES like wine or sherry, for instance. I believe you know what "no" and "none" mean. So, be safe and follow your treatment plan. Any questions, ask your doctor before the weekend gets here because this IS A HOLIDAY WEEKEND!!!
Be well and take good care of you!

From what I've read in the last couple of hours there is no proof of a significant interaction between Metronidazole and alcohol. That said it's better safe than sorry. Now to what I have an issue with. You do not need to wait days and days after drinking 22 ounces of 12 percent beer. That's 2.4 ounces of alcohol. What beer is 12 percent? Anyway the average human can process 1 ounce per hour so 2.5 hours is most likely fine. Double it if you want to 5 hours. After 11 hours you are not going to have an issue.
I know this is old and I know it doesn't matter but I have to do my part when I see complete misinformation. I've been prescribed Metronidazole for diverticulitis many times over the years and while I never mixed them I certainly have had alcohol within a timeframe you have been given. If it were the other way I would wait a couple of days after taking Metronidazole to have a drink but alcohol is processed and gone relatively quickly.

OK, let me first of state that in no way shape or form am I saying that it's OK to drink while taking this drug.
With that being said, I will give you my own personal account. That all. What I have experienced.
Me: 42/6'2/180 white male.
I take Metro from time to time over the past 20 years for my Ulcerative Colitits, now Pouchitis, whenever I have a particularly bad flare up.
Usually 250 MG three time a day.
I am constantly on Cipro.
I heeded the warnings for years, very careful not to ingest alcohol at the RX insistance. But that being said, I like to drink alcohol. But none the less I abstained. Then one year one of my closest cousins got married during a flare up while I was on the drug. When it came time for the champagne toast, I thought to myself I'll be damned if I'm not going to drink a toast, I'm a big boy, I know what will happen and I'll deal with the consequences. So I did it.
I didn't think too much of it at the time, but later I decided to research it a bit. The doctors and pharmacy all used the words "violently ill" if I ingested even small amounts of alcohol. But nothing like damage to the liver or anything permenant, just that you'd get very sick.
So reading the sites, like this, I found that besides getting sick, cramps, barfing, etc, there was no real harm. Just that you would get "violently ill".
So one football afternoon with friends I stupidly decided (do not try this) to drink a beer. I figured I'd drink it really slow and if I started to feel any ill effects I'd immediately stop. Gingerly I drank the beer over an hour.
Hmmm. Well, lets try one more. Nothing. I ended up drinking four beers that day. Nothing.
Over the next few years, I make it a rule to try to not drink on this drug, but in all honesty I have gotten quite inebriated, drinking many beers and doing shots and... nothing.
It's stupid, not smart to do. Maybe I'm a rare case. I don't advise anyone at all to do this. But this is my own personal account. And from my own experience, I seem to be able to drink while taking this drug.
Again, don't drink on this drug.
I felt like I should share, every experience, good or bad, helps to get out there.

Hi pouchitisme, it is always interesting to read individual accounts of how medications affect us... I always thought that you MUST leave 48 hours between drinking and taking this medication. Years ago it would be used to try to control drinking in alcoholics because of its side effects when mixed with alcohol. I think you are a very unusual case. I'm glad you didn't become ill, and thanks for sharing your story
