Warts and verrucas


Warts and verrucas are small lumps on the skin that most people have at some point in their life.  They usually go away on their own but may take months or even years.

Check if you have a wart or verruca

Warts feel firm and rough.  They can appear on palms, knuckles, knees and fingers.

Warts are usually skin coloured but may appear darker on dark skin

Verrucas appear on your feet.  They have tiny black dots under the hard skin.

Some warts are round, flat and can be yellow (plane warts).  You can have many of them.

Clusters of warts, spread over an area of skin (,osaic warts) are common on feet and hands.

Warts do not cause you any harm but some people find them itchy, painful or embarrassing.  Verrucas are more likely to be painful - like standing on a needle.

You can treat warts if they bother you, keep coming back or are painful.

A pharmacist can help with warts and verrrucas

You can buy creams, plasters and sprays from pharmacies to treat warts and verrucas. 

These treatments can take up to 3 months to complete, may irritate your skin and do not always work.  You should not use these treatments on your face.

Your pharmacist can give you advice about the best treatment for you.

Find a pharmacy.

See a GP if:

  • you're worried about a growth on your skin
  • you have a wart or verruca that keeps coming back
  • you have a very large or painful wart or verruca
  • a wart bleeds or changes in how it looks
  • you have a wart on your face or genitals

Genital warts can be treated at a sexual health or GUM clinic.

Find your nearest sexual health service.

Treatment from a GP

A GP may be able to freeze a wart or verruca so it falls off a few weeks later.  Sometimes it takes a few sessions.

If treatment has not worked or you have a wart on your face, your GP might refer you to a skin specialist.  Other treatments include minor surgery and treatment with laser or light.

How to stop warts and verrucas spreading

Warts and verrucas are caused by a virus.  They can be spread to other people from contaminated surfaces or through close skin contact.  You're more likely to spread a wart or verruca if your skin is wet or damaged.

It can take months for a wart or verruca to appear after contact with the virus.
