Overactive Bladder
Urgency, frequency and nocturia — stepwise NICE/BNF-aligned management
Overactive bladder is characterised by urinary urgency, often with daytime frequency and nocturia, with or without urgency urinary incontinence. Safe management starts with exclusion of infection and other serious causes, then follows a structured stepwise pathway from conservative therapy to medicines and specialist options.
What is overactive bladder?
Overactive bladder is a symptom syndrome rather than a single disease diagnosis. The key feature is urgency — a sudden compelling need to pass urine that is difficult to defer — usually accompanied by frequency and nocturia. Some people also have urgency leakage. Clinical evaluation should exclude urinary tract infection, haematuria-related pathology, retention, and other causes before confirming the syndrome for treatment planning.
Stepwise treatment approach
NICE guidance supports conservative treatment first: bladder training, fluid and caffeine modification, and pelvic floor support where mixed symptoms exist. If symptoms remain troublesome, pharmacological therapy is added using either an antimuscarinic or beta-3 agonist based on patient profile, tolerability, blood pressure status, and cognitive risk. Follow-up review is essential to assess benefit, side effects, and whether treatment should be adjusted or switched.
When to escalate
Escalate to specialist care when symptoms are refractory despite optimised conservative and pharmacological treatment, or when red flags appear (e.g., haematuria, recurrent infection, retention concern, neurological signs). Specialist pathways may include botulinum toxin, tibial nerve stimulation, or sacral neuromodulation.
