hi metronidazole and alcohol interaction causes disulfiram-like reaction. this leads to nausea vomiting tachycardia (increased heartbeat) shortness of breath etc. if you had consumed red wine 5 hours before the drug intake then it is all right. there is nothing much to fear. you may have nausea and vomiting but that would be minimal and temporary. 5 hours is ample time for the wine to be metabolized in the body. for further follow up consult a family physician online --> <link>
i took tablet metronidazole 5 hours after i had taken 20 ml of red wine. what can i do now?
