Burning when you urinate, frequent trips to the bathroom, lower abdominal pain, or cloudy urine are common signs of a urinary tract infection (UTI) that should be assessed by a doctor the same day.
Most UTIs are straightforward to treat when diagnosed early, but knowing whether your symptoms can wait until your regular GP opens isn’t always easy.
Today, we explain the common signs of a UTI, when home care isn’t enough, and when it’s time to see an after-hours GP.
A urinary tract infection (UTI) occurs when bacteria, most commonly Escherichia coli from the bowel, enter the urethra and multiply in the bladder. Symptoms can develop within hours and range from mild discomfort to signs of a more serious infection.

Most uncomplicated UTIs can be treated by an after-hours GP with an assessment, urine testing if required, and antibiotics when appropriate.
However, symptoms such as fever, chills, flank pain, persistent vomiting, or confusion may indicate that the infection has spread to the kidneys or has become more serious, requiring immediate hospital assessment.
While anyone can develop a UTI, certain factors make some people significantly more susceptible. Understanding your risk helps you act quickly when the symptoms appear.
Same-day treatment for a UTI is designed to confirm the diagnosis, relieve your symptoms quickly, and reduce the risk of the infection becoming more serious. In most cases, the appointment follows a straightforward process from assessment through to treatment and follow-up advice.
Your GP will begin by asking about your symptoms, when they started, whether you’ve had UTIs before, and any medical conditions or medications that could affect your treatment. They may also ask about pregnancy, recent sexual activity, or other factors that can increase the risk of a UTI.
A urine sample is usually collected during the appointment. A urine dipstick test can detect signs of infection within minutes, helping your GP decide on the most appropriate treatment. If your infection is recurrent, severe, or doesn’t fit the typical pattern, a urine culture may be sent to a laboratory to identify the bacteria causing the infection and determine which antibiotics are most effective.
If a UTI is confirmed or strongly suspected, your GP will prescribe an appropriate antibiotic based on your symptoms and medical history. Most uncomplicated bladder infections begin to improve within 24 to 48 hours of starting treatment. Your GP will also explain how to take the medication correctly and stress the importance of completing the full course, even if you start feeling better.
Alongside antibiotics, drinking plenty of water, avoiding bladder irritants such as caffeine and alcohol, and using urinary alkalinisers recommended by your pharmacist may help ease discomfort while the medication takes effect. If your symptoms aren’t improving after 48 hours, return shortly after finishing treatment, or if you develop a fever, chills, back pain, or vomiting, you should seek further medical assessment, as these may be signs that the infection has spread beyond the bladder.
An after-hours doctor for UTI assessment is the right choice when your regular GP is unavailable, and you need same-day treatment to prevent the infection from worsening overnight. Visit an after-hours doctor for UTI concerns if:
GP After Hours Subiaco offers same-evening treatment for UTI symptoms when your regular clinic is not available.
Located inside SJOG Subiaco Hospital at 175 Cambridge Street, our GPs can assess your symptoms, perform an in-clinic test, confirm the diagnosis, and prescribe the appropriate antibiotic the same night.
A urine culture can be sent to the laboratory if the infection appears complicated or recurrent.
This avoids the long wait times of a hospital emergency department for a condition that, while genuinely uncomfortable, does not require hospital-level care in most cases.
The clinic is open Monday to Friday from 7 pm to 10 pm, Saturday from 1 pm to 7 pm, and Sunday and public holidays from 9 am to 7 pm. Appointments can be booked online 24/7 or by calling 08 9382 9600, and walk-ins are welcome.
If your assessment reveals signs of kidney involvement or complications, the GP can refer you appropriately the same night, with consultation notes faxed directly to your regular GP for continuity of care.
You will not be left to manage a progressing infection at home without a clear next step.
In very mild cases in healthy, non-pregnant adults, a UTI may occasionally resolve without antibiotics. However, this cannot be reliably predicted, and the risk of the infection spreading to the kidneys makes self-resolution a gamble. Most GPs recommend treating confirmed UTIs with antibiotics to reliably and quickly clear the infection.
Recurrent UTIs, defined as two or more in six months or three or more in a year, are relatively common in women. Causes can include incomplete bladder emptying, sexual activity, urogenital anatomy, hormonal changes after menopause, or a structural issue with the urinary tract. A GP can investigate the underlying cause and discuss preventive strategies.
Yes, men can develop UTIs, although they are less common than in women.
UTIs in men are more likely to have an underlying cause, such as an enlarged prostate or a structural issue, and typically warrant further investigation rather than a simple antibiotic course.
It is advisable to avoid sexual activity until your UTI has fully resolved and you have completed your course of antibiotics. Sex during a UTI can worsen symptoms, introduce additional bacteria, and delay recovery.
Most people notice significant improvement in the symptoms within 24 to 48 hours of starting antibiotics. The full course, typically three to seven days depending on the antibiotic prescribed, should always be completed even if symptoms resolve earlier. Stopping early increases the risk of the infection returning and of antibiotic resistance.
