Do not use metronidazole vaginal if you have ever had an allergic reaction to it.
Before using metronidazole vaginal, tell your doctor if you have liver disease, a seizure disorder, problems with circulation (such as Raynaud’s syndrome), or if you have taken disulfiram (Antabuse) within the past 14 days.
Avoid having sex until your vaginal infection has been completely treated and you have finished using the medication.
Avoid using other vaginal creams or douches at the same time as metronidazole vaginal unless your doctor approves.
Use metronidazole vaginal for the entire length of time prescribed by your doctor, even during your menstrual period. Your symptoms may get better before the infection is completely treated.
If the infection does not clear up after you have finished one course of therapy, or if your symptoms get worse, see your doctor. You may have another type of infection that metronidazole will not treat.
