Been taking doxycycline 7 weeks prostatitus helped but not much can't take cipro (ciprofloxacin) need a stronger antibiotic what is another good choice?

Maybe none...: If doxycycline didn't clear it up, it is unlikely that any other antibiotic will do so. Most prostatitis isn't an infection; antibiotics usually are tried but often don't help. Return to the doctor or clinic who prescribed treatment. If in doubt about doctor's expertise, you won't go wrong with one of your country's excellent NHS genitourinary medicine (GUM) clinics. Or a urologist. Good luck!
