Can cranberry juice fight a UTI that is already present, or does it only prevent them?

Weak action. Cranberry juice is a weak UTI preventative and virtually of no use in treating an active uti. Most utis burn themselves out without medication, as used to happen in olden times before the advent of antibiotics, unless there is a structural abnormality of the urinary tract. Drinking plenty of liquids and a short course of antibiotics are best weapons against utis.

Can I prevent a UTI with herbs or natural remedies like cranberry juice?

The evidence says... The evidence says..... No. If you are male with a uti, see a urologist. If you are female: stay hydrated, always urinate after sexual intercourse, and make sure you "try" to urinate at least ever 2-3 hours while awake. If you are doing all of the above and still getting uti's, see you doctor asap. There is no evidence that cranberry or other "natural" remedies work. Read more...
PROBABLY. Uti prevention begins with good hygiene - wipe away from the urethra, urinate after sexual contact, drink plenty of water, etc. Many herbs inhibit bacteria & can be used successfully on as needed basis (before sexual activity for example). Some to consider are intermittent uva ursi or cranberry. Don't use together since they work at different pH levels. Respect herbs since you can be allergic. Read more...

Maybe. Studies are not consistent with some suggesting benefit and others finding no benefit. Theoretically, cranberry juice may work because it contains a substance that inhibits the ability of bacteria to attach to cells that line the urinary tract. There is no reason not to try it. Read more...

Cranberry no help. Cranberry juice won't help much. For a long time, it was believed cranberry juice or pills could prevent or cure UTIs, but recent research and shows no significant benefit, and mnost expers agree. Make sure you have been tested for STDs, which can cause UTI-like symptoms and are very common at your age of 21. You need to see a doctor, and stick with the same doctor over time. Good luck!
