General Information

Warts are benign growths of skin caused by the human papillomavirus (HPV). The HPV virus is transmitted by direct skin-to-skin contact.

There are many types of warts and this topic deals with ‘common’ viral warts, which mostly occur on the back of the hands and fingers (less commonly on the elbows and knees). Warts are usually painless and may occur singly or in crops. Most have a cauliflower-like appearance and tiny black dots are usually present within the wart.

Warts are more common in children, with most occurring in adolescents aged 12 to 16 years. Most common warts are self-limiting and disappear by themselves within 2 years. However, most people will seek treatment for cosmetic reasons.

See Your Pharmacist or Medical Professional

  • if the person with the wart is aged over 50 years
  • if the warts are located in other parts of the body as well as the hands (e.g. feet, face, genital region)
  • if there are multiple or widespread warts
  • if you are unsure if it is a wart or some other skin condition
  • if there is any itching or bleeding associated with the wart
  • if the wart has a reddish colour or has changed colour
  • if the wart looks smooth or has a central dimple
  • if the wart has grown recently
  • if you are pregnant or breastfeeding; some treatments may not be suitable

Treatment Tips

  • do not pick, bite or scratch warts since this may encourage spread to other parts of the body
  • most warts will clear up within two years without treatment
  • when using topical products, protect surrounding skin by cutting a hole in a plaster and placing it over the wart, leaving the wart exposed. Alternatively, apply petroleum jelly (Vaseline) to the surrounding skin
  • be patient when using products, since most warts take up to 12 weeks to treat
  • if treatment is unsuccessful you can ask the pharmacist to recommend an alternative product or visit your GP for liquid nitrogen therapy, which freezes the warts
