I would wait 3 or 4 days before adding in the next Rx. If she has an allergic reaction it usually happens sooner than later (but not always).
I would recommend starting with Nystatin first for a full week to help reduce candida, then add Zith (usually well tolerated), then plaq (also pretty benign), and doxy last. I'm sure others will chime in also
