How effective is cipro (ciprofloxacin) for uti / gastroenteritis?

Depends: It depends on the infection.For utis in our part of the country we find lot of resistant organisms and treatment with Cipro (ciprofloxacin) is not successful.So it has lost favour to other antibiotics as starting drug for a uti for gastroenteritis we do not use or recommend antibiotics including Cipro (ciprofloxacin) due to increased resistance and rarely antibiotics for severe symptoms azithromycine or bacrim is preferred.
