I know I've read somewhere around here about someone who places actual antibiotic pills into their bladder. The ones meant for oral consumption. How do you do that? Is it safe? Being as it's meant to go to the stomach and not bladder. Is it actually effective? What about comparison to say gentamicin bladder instillation that's MEANT to go into the bladder? Why do it will the pills instead of gentamicin, is it a cost/acquiring gentamicin issue?

Obviously this is an off label use. I'm looking for responses from the people who actually do it. I don't think anyone in the medical field would recommend it...
