antibiotics are the first line of treatment in acute prostatitis (cat. i). antibiotics usually resolve acute prostatitis infections in a very short period of time. appropriate antibiotics should be used, based on the microbe causing the infection. some antibiotics have very poor penetration of the prostatic capsule, others, such as ciprofloxacin, co-trimoxazole and tetracyclines penetrate well. severely ill patients may need hospitalization, while nontoxic patients can be treated at home with bed rest, analgesics, stool softeners, and hydration.
