How long until medication fully kicks in?

Patient: I started doxycycline for prostatitis that I got from an Urinary Tract infection. I’ve been on the medication for two weeks and while all severe symptoms have gone away I still notice that my stream when peeing is not completely normal how long until all symptoms will subside?

Symptoms: Prostatitis from a UTI

Doctor: Thanks for your answer.Usually Urinary tract infections take 3 weeks to resolve and to be sure of your cure from UTI, you need to get one culture & sensitivity of urine to see it is sterile.Hope it helps.
