ANSWER: Howard

Antibiotics can cure infections, but when there are repeated infections something else is wrong. It could be prostate obstruction, diabetes, stones, poor personal hygiene or incomplete bladder emptying.

Usually we try to treat underlying good problems well as just the infection. Your internist is not going to be able to do this. If you are not happy with your current urologist, please consult another.

Low dose prophylaxis with antibiotics is reasonable in some cases, particularly when no underlying problem has been found.

QUESTION: I have enlarged prostate and take Flomax and proscar.I had urine test 2 months ago it was normal.now  urinatingf hour no other symptons.urine is clear    does frequent urination only withno symptons usually mean infection.lastn time I used doxycycline and neurofin.think I can use them again


Frequent urination does not necessarily mean a UTI as it can also be due to overactive bladder, polyuria, diabetes and incomplete emptying. You should not take antibiotics unless approved by your physician. For example, any remaining infection is now likely to be resistant to your original antibiotic so it may be reasonable tovswitch.
