Viral warts and verrucas are benign and self-limiting and can be managed within primary care.
NHS England (NHSE) has published new prescribing
guidance for various common conditions for which over-the-counter (OTC) items should not be routinely prescribed in primary care (quick reference guide). One of these conditions is warts and verrucae.
Many of these products are cheap to buy and are readily available OTC along with advice from pharmacies. Some self-care medicines are available from shops and supermarkets. Please click
here for further information, exceptions, and a patient leaflet.
Cryotherapy is not appropriate for viral warts on the hands and feet since it is painful; it can cause significant scarring and can exacerbate the condition. Surgical treatment is inappropriate for these lesions.
