Well you'll know on monday

Generally, antibiotics are given for as long 6-8 weeks and can be considerably longer.
If you keep getting this, instead of acute bacterial prostatitis, they refer to it as chronic bacterial prostatitis. Which means you can get it over and over at different points and have to be treated each and every time.
The usual drugs to treat this are Trimethoprim-sulfamethoxazole and ciprofloxacinare. Tetracycline,
Carbenicillin, Erythromycin and Nitrofurantoin can also be used.
Good luck on monday.
