Scabies is one of the most common skin infestations seen in UK community pharmacies. Caused by the mite Sarcoptes scabiei, it produces intense itching — particularly at night — and a characteristic rash that can affect anyone regardless of hygiene. According to the British Association of Dermatologists, scabies remains a significant public health concern, with outbreaks occurring in households, care homes and schools across England.

Community pharmacists are often the first healthcare professional a patient consults, and effective over-the-counter treatment is available without a prescription.

Recognising scabies

The hallmark of scabies is persistent, intense itching that worsens at night. Patients may describe a rash with small raised spots, particularly in the web spaces between fingers, on the wrists, elbows, armpits, waist and buttocks. In infants and young children, the scalp, face, palms and soles may also be affected.

Burrow tracks — fine, thread-like lines in the skin — are diagnostic but not always visible. The rash itself is an allergic reaction to the mite, its eggs and faeces, and may take four to six weeks to develop after initial infestation. This delay means patients can be infectious before symptoms appear.

Over-the-counter treatment options

Two main treatments are available from UK pharmacies without prescription:

Permethrin 5% cream (Lyclear Dermal Cream)

Permethrin is the first-line treatment recommended by NICE and the British National Formulary. It is applied to the entire body from the chin downwards, left on for 8–12 hours (typically overnight), then washed off. A second application is required seven days later to kill any mites that have hatched from surviving eggs.

Key counselling points for pharmacists to convey:

• Apply to cool, dry skin — not after a hot bath, as vasodilation increases absorption and reduces skin-surface contact time
• Include between fingers and toes, under nails, the soles of the feet, and skin creases
• Reapply to hands if washed during the treatment period
• One 30g tube is usually sufficient for an adult; two tubes may be needed for larger patients

Malathion 0.5% aqueous lotion (Derbac-M)

Malathion is the second-line option, used when permethrin is contraindicated or has failed. It is applied similarly to the whole body, left on for 24 hours, then washed off. A repeat application after seven days is recommended.

Malathion is an organophosphate and should be avoided in patients taking anticholinesterase medications. It is also not recommended in pregnancy or breastfeeding without GP guidance.

Treating household contacts

This is where pharmacy advice is critical. All household members and close physical contacts must be treated simultaneously, even if they have no symptoms. The four-to-six-week incubation period means contacts may be infested but asymptomatic, and untreated contacts are the most common cause of reinfection.

Pharmacists should ask about:

• Partners, children and anyone sharing a bed
• Other household members
• Close contacts outside the home (e.g. sexual partners, carers)

All contacts should apply treatment on the same day. Without simultaneous treatment, the cycle of reinfestation continues indefinitely.

Environmental measures

On the day of treatment, patients should:

• Wash bed linen, towels and clothing at 50°C or above
• Items that cannot be washed should be sealed in a plastic bag for 72 hours (mites cannot survive more than 72 hours away from human skin)
• Vacuuming soft furnishings is advisable but not essential — mites on furniture are rarely the source of reinfestation

When to refer to a GP

Pharmacists should refer patients in the following circumstances:

• Infants under two months of age
• Pregnant or breastfeeding women (though permethrin is considered first-line in pregnancy, a GP should confirm)
• Patients with crusted (Norwegian) scabies — a severe, highly contagious form seen in immunocompromised individuals and care home residents, which requires oral ivermectin
• Treatment failure after two complete courses
• Secondary bacterial infection of excoriated skin (impetigo or cellulitis)
• Widespread eczematous reaction requiring topical corticosteroids

Post-treatment itch

Patients should be warned that itching can persist for two to four weeks after successful treatment. This post-scabies itch is a hypersensitivity reaction, not evidence of treatment failure. Crotamiton cream (Eurax) or a mild topical corticosteroid (hydrocortisone 1%) can help manage residual symptoms. Antihistamines such as chlorphenamine may help with sleep if nocturnal itching persists.

If new burrows appear or itching worsens after the initial post-treatment period, reinfestation or treatment failure should be considered and the patient should return for assessment.

The pharmacy's role

Community pharmacies are ideally positioned to manage uncomplicated scabies. The condition is common, the treatments are available without prescription, and the most important intervention — ensuring all contacts are treated simultaneously — is primarily a counselling task. According to PharmSee's tracker, there are currently 1,715 active pharmacy job vacancies across England, reflecting the continued demand for pharmacists delivering these frontline consultations.
