HI!
I don't blame you for feeling confused! If you have the option, go to a different hospital next time. I wonder if the results they gave your wife were actually hers or whether she was confused with someone else. It sounds like they got all the answers wrong.
MOST importantly--the
MetronidazoleMetronidazole
Metronidazole benzoate
Metronidazole topical
Metronidazole vaginal will NOT hurt the baby.
We used to recommend against prescribing it in the first trimester because of some data derived from studies on bacteria. Within the past 10 years or so, it has been considered safe to use even in the first trimester, although many doctors will avoid it because of its history. There is no increased risk associated with taking this medication.
Your wife could certainly stop taking it at this point however. Since all of the information that you were given at the hospital was questionable, I would probably advise my own patient to stop. I would also advise my own patient to obtain a copy of her records from that ER visit to take to her Obstetrician. Her MD may be able to help her sort out what was going on with the tests--she may never have had trichomonas in the first place.
By the way--congratulations on the pregnancy!
Good luck!
Dr B
