Calamine with zinc oxide

How it works

It acts as a mild astringent and provides a cooling, soothing effect on the skin that helps relieve pruritus, with zinc oxide also offering mild protective properties.

Prescribing in practice

• It provides only symptomatic relief and does not treat the underlying cause of itch, which should be identified and managed.
• Calamine lotion can dry the skin and may need an emollient alongside it for dry or eczematous skin.
• Avoid contact with the eyes and broken skin where not appropriate.

Monitoring

Review symptomatically to confirm relief of itch and to reconsider the diagnosis if symptoms persist.

Counselling the patient

• Shake the lotion before use and dab onto the itchy area, allowing it to dry.
• It is for symptom relief only and can be reapplied as needed.
• Use a moisturiser as well if the skin becomes too dry.
