I had two cases of UTI this year and took Nitrofurantoin both times. It didn't give me any side effects. The first course was only a 3 day one and I don't think that fully cleared the infection - hence the UTI coming back. The second course was 7 days and, touch wood, I think that cleared it.
You could ask your GI doc if you could switch to that. But unless the side effects are intolerable I really would try to finish the course - the UTI is liable to come back unless you bosh all
the bacteria. Plus not finishing courses of antibiotics contributes to future antibiotic resistance.
