Hello
I have gone through your question.
I can understand your concern.
Antibiotics are medicines that can cause
nausea or
vomiting.So,i can say that Metronidasole and
Cipro could be potential causes of her symptom.
At the other side,nausea, vomiting and
diarrhea are some of the most common side effects people have when they first start taking
metformin.
We can exclude metformine ,if this is not the first time that your daughter take this drug.
My advice for you is:Call the doctor who prescribed the medicine to your daughter,to find out whether you should stop taking it or take a different one.
Hope this information is helpful.
If you have otehr doubts,feel free and ask.
Best regards.
