Can you flush out a UTI with water?
No. Drinking water can support hydration and may help with comfort, but it does not reliably eliminate an established bacterial UTI. If you develop burning, urgency, frequent urination, pelvic discomfort, or blood in your urine, contact a pharmacist or another healthcare professional promptly.

Myths and evidence
What helps prevent UTIs—and what does not treat one?
| Question | Direct answer |
|---|---|
| Can water flush out a UTI? | Hydration may support comfort and urinary health, but it does not replace assessment or antibiotics when prescribed. |
| Does cranberry juice cure a UTI? | No. Cranberry products may help some people reduce recurrence, but they do not treat an active infection. |
| Can over-the-counter products cure a UTI? | No. Some products may reduce discomfort, but they do not eliminate the underlying bacterial infection. |
Evidence: Ontario College of Pharmacists UTI assessment algorithm and the Cochrane review of cranberry products for prevention.
Five practical habits
Everyday steps that may lower UTI risk
Keep hydrated throughout the day
Drink fluids regularly so you stay hydrated and urinate normally throughout the day. Water is a simple choice. There is no single amount that is right for everyone, and drinking extra water does not replace treatment if an infection has started.
If you have kidney, heart, or liver disease—or have been told to limit fluids—ask your healthcare professional before increasing how much you drink.
Keep blood sugar within your target range if you have diabetes
High blood sugar can increase the risk of urinary tract infections. Follow the diabetes plan you made with your healthcare team, take medicines as directed, and monitor your blood sugar as recommended.
If you have diabetes and develop UTI symptoms, seek professional assessment promptly. People with diabetes can face a higher risk of complications from an infection.
Wipe from front to back
After using the toilet, wipe from front to back—especially after a bowel movement. This may help reduce the transfer of bacteria from the anal area toward the urethra.
Use gentle hygiene and avoid harsh or heavily scented products that may irritate sensitive skin.
Consider urinating after intercourse
Urinating soon after sexual intercourse is a commonly recommended habit, particularly for people who notice UTIs occurring after sex. It may help clear bacteria near the urethra.
If you experience frequent or recurring UTIs, speak with a pharmacist or prescriber. Recurrent symptoms deserve an individual assessment rather than repeated self-treatment.
Get help when UTI symptoms begin
Do not rely on water or home remedies to “flush out” a possible infection. Contact a pharmacist or another healthcare professional when symptoms begin.
Ontario pharmacists can assess eligible uncomplicated UTIs and may prescribe an approved antibiotic when appropriate. A prescription is not automatic; the safest next step may be treatment, self-care advice, testing, or referral.
Recurrent symptoms
What if UTIs keep coming back?
Two UTIs within six months or three within 12 months are considered recurrent in the Ontario pharmacist assessment algorithm. A relapse means symptoms return within four weeks after finishing antibiotic treatment. Recurrent or relapsing symptoms need medical assessment rather than repeated self-treatment.
Diabetes, menopause, spermicide use, incomplete bladder emptying, urinary-tract conditions, and recent antibiotic use can affect risk or the next step. These factors require individual assessment; they are not a self-diagnosis checklist.
Know the signs
Common UTI symptoms

- burning or pain when urinating
- needing to urinate more often or urgently
- passing only small amounts of urine

Frequently asked questions
UTI prevention and treatment FAQs
Can you flush out a UTI with water?
No. Drinking water can support hydration and may help with comfort, but it does not reliably eliminate an established bacterial UTI. Contact a pharmacist or another healthcare professional when symptoms begin.
Does cranberry juice cure or prevent a UTI?
Cranberry juice does not cure an active UTI. Some cranberry products may help reduce recurrent UTIs for some people, but evidence and product formulations vary. Ask a healthcare professional before relying on a supplement, especially if you take medicines that may interact with it.
Can a pharmacist prescribe antibiotics for a UTI in Ontario?
Ontario pharmacists can assess eligible uncomplicated UTIs and may prescribe an approved antibiotic when appropriate. Pregnancy, male patients, children under 12, fever, flank pain, vomiting, recurrence, and other complicating factors generally require referral.
When should UTI symptoms be treated urgently?
Seek prompt medical care for fever or chills, flank or back pain, nausea or vomiting, confusion, pregnancy, severe weakness, rapidly worsening symptoms, or feeling very unwell. These can suggest a kidney infection or another condition that needs medical assessment.
What counts as a recurrent UTI?
The Ontario pharmacist assessment algorithm defines recurrent infection as two or more UTIs within six months or three or more within 12 months. Relapse means symptoms return within four weeks after finishing antibiotic treatment. Recurrent or relapsing symptoms should be referred for medical assessment.
