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.
