I have microscopic hematuria, urinary urgency frequency and discomfort. doctor said maybe its a prostatitis. hes given me levofloxacin for 3weeks. how long does this antibiotic takes effect and treat the hematuria? any help. thanks.

Prostatitis?: As discussed in 2 other questions, if prostatitis, it's probably non-bacterial and levofloxacin won't work. Antibiotics are often tried in hope they will help, but usually make no difference. But prostatitis usually does not cause these symptoms and hematuria. Maybe you have interstitial or hemorrhagic cystitis, which are a side effect of some drugs, or occur on their own. RU seeing a urologist?
