Contact a clinician promptly, especially if symptoms are severe, worsening, or you’re pregnant, male, immunocompromised, have kidney disease, or have recurrent UTIs
Start prescribed antibiotics as directed if you’re evaluated and diagnosed
Drink plenty of water to help flush your urinary tract
Use a heating pad or warm compress on the lower abdomen or back for discomfort
Use over-the-counter phenazopyridine for short-term symptom relief (follow label directions; do not use longer than 2 days unless told by a clinician)
Use OTC pain relief such as ibuprofen or acetaminophen if you can take them safely
Avoid bladder irritants: caffeine, alcohol, carbonated drinks, and spicy/acidic foods
Urinate when you feel the urge; don’t hold urine
Consider cranberry products if you prefer (may help some people prevent recurrence; do not delay medical evaluation if you have significant symptoms)
If you use a catheter or have an underlying urologic condition, seek medical advice quickly
Seek urgent care or emergency help if you have fever, chills, flank/back pain, nausea/vomiting, blood in urine with clots, confusion, or you’re unable to keep fluids down
Get same-day evaluation if symptoms are new and you suspect a UTI, especially if you don’t improve within 24–48 hours after supportive care
