Should I add Cipro to my Flagyl to try and kill the Blasto?

I have about 10 days worth on hand and have read these two have been used together (not very successfully however). But, if there is a slight chance of killing it by adding the Cipro, I will do it. Anyone know anything about this? I was on Cipro for two weeks recently alone--because of my white blood cell count being so high. Not sure how this will respond.
