Ciprofloxacin is available only by prescription and is used to treat certain bacterial infections. It comes in a variety of strengths and forms, including eye drops and ear drops. Ciprofloxacin ophthalmic (eye) drops are used for treating bacterial conjunctivitis (also called  pink eye ) and corneal ulcers.
Ciprofloxacin and dexamethasone for the ear(s), or Ciprodex, will start killing bacteria and decreasing swelling immediately. It takes time for it to work and for the infection to resolve, however. You should start to feel better as soon as a few days after you begin using it, but this does not mean you should stop. It is very important to finish the prescription. Call your doctor if you do not get better after one week.
