I did the same thing - was on doxy and zithromax (same drug class as biaxin), and i switched from doxy to bactrim. I waited 2 days just to give my system a rest, not for any other reason. It will not negatively affect your treatment, since you are still on the biaxin, but it's up to you. and it also doesn't hurt to take a "drug holiday" for a day or two, just be prepared to herx - if you do herx, that is.
I took this drug combo for lyme and bartonella, so it is a good choice! I just prefer zithromax bc biaxin kills my stomach, no matter what I eat with it. I also hate the aftertaste, but if it works for you, stick with it!!
