How to treat an ear infection without cipro (ciprofloxacin)?

I assume you..: Are talking about an external ear infection and referring to Cipro (ciprofloxacin) drops. If so, a 50:50 mixture of white vinegar and rubbing alcohol works well for killing bacteria and fungus. I recommend using it twice a day and flushing the canal with peroxide at the end of the day. If that doesn't improve things over a 3 to 4 day period you should see a doctor.
