@kaybast I don't know what oral antibiotics topically will do, but it's a good hypothesis. You can call a doc anytime if you think the meds are causing problems. The dizziness is a concern. I wouldn't wait. I'm always concerned when I need gloves for meds I'm putting in my body. I was a Chemo RN and I won't put that stuff in me either. (I cured my own cancer.) Special gloves, tubing , and disposal units. Yikes! I've gone holistic in my old age for a good reason. Do you have chronic sinus infections? They claim that the antibiotic doesn't go systemic with the sinus rinses but anything that goes into you becomes systemic after awhile. Another lovely side effect of Cipro is dizziness.
