I would think it would increase the infection's resistance to antibiotics, so counter-productive. Ask your doctor though. The best way to avoid UTIs is to drink plenty of water.

This is a great help. It confirms my own reservations on using Sulfamethoxazole
(bactrim) more than the usual ten days prescription.

The answer is actually more complicated than a simple Yes or No. One needs to determine if there are underlying causes, e.g., in women, vaginal prolapse, anatomic distortions of the pelvic area due to multiple childbirths, urinary retention due to meds(anticholinergics in PD patients), chronic vesicoureteral reflux (urine flows back up into the ureters which carry urine from the kidneys to the bladder), UTI's triggered by intercourse, chronic dehydration, chronic constipation wherein stool stuck in the colon area near the anus prevent full bladder emptying, fistulas(an abnormal conduit from the bowel to the bladder), and many others. Bladder stones or recurrent kidney stones can cause UTI's in both sexes. In men, causes include an enlarged prostate that restricts emptying of the bladder, blockages or scarring in the urethra(tube that carries urine from the bladder down into the penis and hence out, meds(anticholinergics) or medical conditions such as PD that impair bladder drainage. Dehydration and constipation can also affect men.

It is correct that long-term usage of antibiotics for this can select for resistant bacteria that can be more difficult to treat . Sometimes, however there is no alternative.

Recent medical studies have shown that some more traditional treatments such as supplements of d-mannose or cranberry juice are not very effective. If you have diabetes, cranberry pills are better since they have much less sugar.

Methenamine hippurate (is not an antibiotic) can be used. .

The most important step is to see a urologist who can do a full exam, document if having bonafide UTI's, pin down cause and tailor treatment appropriately.

Other advice includes maintaining good hydration, especially during hot weather, watch urine color(the more yellow it is, the more water you need to drink, although some meds like the PD med Entacapone can discolor urine brownish orange). Women should get up and void as soon as possible after intercourse. Both sexes should not hold urine for overly long periods of time.

Hope this helps.

I agree with that and doctors or some time for reluctant to prescribe anabiotic‘s as freely as I did 15 to 20 years ago when they gave anabiotic‘s for everything.
