Cystitis/Urinary Tract Infection

An uncomplicated Urinary Tract Infection (UTI) often referred to as cystitis is a common bacterial infection of the lower urinary tract, specifically the bladder and urethra.

It is called "uncomplicated" when it occurs in an otherwise healthy, non-pregnant woman whose urinary tract has normal anatomy and function.

UTIs occur when bacteria (most commonly Escherichia coli or E. coli, which naturally live harmlessly in the gut) enter the urethra and travel upward into the bladder. Because women have a shorter urethra than men, it is much easier for bacteria to reach the bladder and cause localized inflammation.

​

Common Symptoms of a Lower UTI

  • Dysuria: A sharp burning, stinging, or painful sensation when passing urine.

  • Frequency & Urgency: Feeling the sudden, intense need to urinate more frequently than usual, often passing only small amounts.

  • Lower Abdominal Discomfort: A persistent ache or pressure in your lower stomach or pelvic area.

  • Urine Changes: Cloudy, dark, or strong-smelling urine (sometimes containing traces of blood).

Options to Manage a UTI

Managing a UTI involves a combination of supportive self-care to ease discomfort and targeted antibiotic treatment to clear the bacterial infection.

1. Supportive Self-Care & Symptom Relief

  • Stay Hydrated: Drink plenty of fluids (mainly water) to help flush bacteria out of your urinary tract naturally.

  • Over-the-Counter Pain Relief: Paracetamol or ibuprofen can help relieve pelvic pain, fever, and general discomfort.

  • Sodium / Potassium Citrate Products: Over-the-counter cystitis sachets help make urine less acidic, reducing the sharp burning sensation during urination (note: these soothe symptoms but do not kill the bacteria).

  • Avoid Irritants: Steer clear of caffeine, alcohol, fizzy drinks, and acidic fruit juices, which can further irritate an inflamed bladder lining.​

​

2. Prescription Antibiotic Treatments

While mild symptoms sometimes resolve with high fluid intake, prescription antibiotics are the most reliable and direct way to eliminate the bacteria, prevent the infection from spreading upward to the kidneys, and ensure quick symptom relief.

1. Nitrofurantoin MR 100mg Modified-Release Capsules

  • Role: First-Line Standard Treatment (Twice Daily)

  • How It Works: Nitrofurantoin concentrates specifically inside your bladder and urine rather than your whole body. Once inside bacterial cells, it damages bacterial DNA and essential enzymes, preventing them from surviving.

  • Key Benefit: Because it concentrates directly in the urinary tract, it targets the infection where it matters most while minimizing disruption to healthy bacteria elsewhere in the body.

  • Dosing: Taken twice daily (every 12 hours) with food or milk for 3 days. The modified-release (MR) formula releases the active medicine slowly, allowing for convenient twice-a-day dosing.

2. Nitrofurantoin 50mg Standard Capsules

  • Role: First-Line Standard Treatment (Four Times Daily)

  • How It Works: Contains the exact same active antibacterial ingredient as the MR version, providing targeted action inside the bladder.

  • Key Benefit: An alternative immediate-release formulation suitable for patients who require a standard dosing schedule.

  • Dosing: Taken four times daily (spaced evenly throughout the day) with food or milk for 3 days.

3. Cefalexin 500mg Capsules

  • Role: Second-Line / Alternative Treatment

  • How It Works: Cefalexin is a cephalosporin-type broad-spectrum antibiotic. It works by interfering with the formation of the bacteria’s cell wall, causing the bacterial cell to break open and die.

  • When to Select: Prescribed when Nitrofurantoin is not clinically suitable. For example, in patients with reduced kidney function (where Nitrofurantoin cannot reach effective levels in the urine), known resistance, or specific medication intolerances.

  • Dosing: Typically taken two to three times daily for 3 to 7 days, as directed by your clinician.
