The Nitrofurantoin, which is the generic for Macrobid, is what I used while pregnant
, and it cleared my UTI up everytime. Vomiting and nausea is a side effect of the macrobid, and in the future, I would tell my doctor that it caused you to be sick. They can try something else and hopefully it won't make you feel so bad.
Most common antibiotics used to treat UTI's are: Macrobid, Augmentin, Cipro, Amoxicillin, etc. It really depends on the type of bacteria that is present in the urinary tract.
