in general metronidazole is very harsh on the stomach and can cause nausea vomiting and upset stomach. it is recommended to take with food and to avoid alcohol which has a drug-drug interaction (will cause vomiting). if you daughter is pregnant i would not take this medication and would seek advice from your doctor as to why or if another medication can be prescribed. have your daughter-in-law contact her ob-gyn to see if he/she feels safe with her taking this medication. also ask your ob-gyn if they have a list of medications that they believe are safe to take during pregnancy.
my daughter-in-law is pregnant and was prescribed metronidazole. she immediately vomited. what can we do?
