Benign prostatic hyperplasia — non-cancerous enlargement of the prostate gland — affects approximately 50% of men aged over 50 and up to 80% of men by age 80, according to the British Association of Urological Surgeons (BAUS). Lower urinary tract symptoms (LUTS) caused by BPH are among the most common reasons men visit their GP, but many men first seek advice at the pharmacy counter.

Community pharmacists are often the first healthcare professional a man will approach about urinary symptoms — partly because the pharmacy consultation feels less formal than a GP appointment, and partly because many men delay seeking help for urological symptoms due to embarrassment.

Recognising BPH symptoms at the counter

Men presenting with the following symptoms may have BPH-related LUTS:

Storage symptoms (irritative):

• Frequency — needing to urinate more than 8 times per day
• Urgency — a sudden, compelling need to urinate
• Nocturia — waking more than once per night to urinate

Voiding symptoms (obstructive):

• Hesitancy — difficulty starting urination
• Weak stream
• Straining to urinate
• Terminal dribbling
• Incomplete emptying

These symptoms overlap significantly with other conditions, including prostate cancer, urinary tract infection, overactive bladder and diabetes. Pharmacists should not diagnose BPH — that requires clinical examination and investigation — but can identify the symptom pattern and recommend appropriate action.

What pharmacists can supply

OTC options

The OTC options for BPH are limited compared to prescription therapies:

Tamsulosin: In several countries, tamsulosin 400mcg is available OTC for men aged 45–75 with BPH symptoms. In the UK, tamsulosin OTC was available as Flomax Relief from 2010 but was voluntarily withdrawn by the manufacturer in 2018 for commercial reasons. It remains prescription-only in practice. Pharmacists should not supply tamsulosin without a prescription.

Lifestyle advice

Evidence-based lifestyle modifications that pharmacists can recommend:

• Fluid management: avoid excessive fluid intake (more than 2 litres daily is unnecessary for most men). Reduce evening fluid intake to manage nocturia
• Caffeine and alcohol reduction: both increase urinary frequency and urgency
• Bladder training: try to increase intervals between voiding to improve bladder capacity. Urge suppression techniques (mental distraction, pelvic floor contraction)
• Double voiding: after finishing urination, wait 30 seconds and try again to improve emptying
• Avoid constipation: a full rectum presses on the prostate and worsens urinary symptoms. Dietary fibre and adequate hydration help
• Review medicines: alpha-blockers (prescribed for BPH) can cause dizziness; antimuscarinics (for OAB) can worsen retention; decongestants (pseudoephedrine, phenylephrine) can worsen BPH symptoms — flag OTC decongestant purchases

Medicines to avoid recommending

Pharmacists should be aware that several common OTC medicines can worsen urinary symptoms in men with BPH:

• Pseudoephedrine and phenylephrine (cold and flu remedies): alpha-adrenergic agonists that increase smooth muscle tone in the prostate and bladder neck, potentially causing acute urinary retention
• Antihistamines with strong anticholinergic effects (chlorphenamine, diphenhydramine): can reduce bladder contractility and worsen retention
• Codeine: constipation worsens BPH symptoms

A man presenting with urinary symptoms who also asks for a cold remedy containing pseudoephedrine should be advised to choose an alternative decongestant or a pseudoephedrine-free product.

When to refer

Community pharmacists should refer men to their GP when:

• Urinary symptoms are new or worsening — needs examination and PSA testing to exclude malignancy
• Haematuria (blood in urine) — urgent referral required
• Acute urinary retention (complete inability to pass urine with a painful, distended bladder) — this is a medical emergency. Call 999 or direct to A&E
• Recurrent urinary tract infections in a man — uncommon and requires investigation
• Significant nocturia (three or more times per night) affecting quality of life
• Family history of prostate cancer — lower threshold for investigation
• Age under 45 with urinary symptoms — BPH is unusual at this age; other diagnoses should be considered

PSA testing: what pharmacists should know

Pharmacists are often asked about the prostate-specific antigen (PSA) blood test. Key points:

• PSA is not a screening test — the UK National Screening Committee does not recommend population PSA screening
• An elevated PSA can indicate BPH, prostatitis or prostate cancer — it is not specific
• Men aged 50 and over can request a PSA test from their GP (the "informed choice" programme)
• Physical activity, urinary tract infections and ejaculation can temporarily elevate PSA — advise patients to discuss timing with their GP

Pharmacists should neither encourage nor discourage PSA testing, but should ensure that men requesting information understand both the benefits and limitations of the test.

The pharmacy role

BPH is a condition where pharmacy can make a real difference in care pathways — not through treatment, but through early identification, appropriate referral and harm avoidance. The pharmacist who recognises BPH symptoms, avoids supplying medicines that could worsen them, and encourages timely GP assessment is providing clinical value that no other healthcare professional in the community routinely delivers.
