Warts & Verrucas

Let’s face it, getting a wart or verruca can feel a bit embarrassing. But just because something might feel embarrassing doesn’t mean you should be embarrassed. After all, warts and verrucae are just the result of an infection with the human papillomavirus (HPV).¹ HPV is incredibly common, meaning 5–30% of school age children and adults have warts.² … Read More See less

Warts and verrucae usually go away on their own.³However, they can take a long time to clear up, which can be frustrating.^3,4 There are things you can do to try and make them clear up more quickly.³But even if you might feel self-conscious about them, warts and verrucae aren’t usually a cause for concern.⁵

What are warts and verrucae?

Cutaneous warts are small, benign (non-cancerous) growths that are caused by an infection with HPV.^1,5 There are over 100 subtypes (strains) of HPV, but only a few types can cause warts.⁵

Warts are generally harmless, but they can be sometimes painful and make it difficult to wear shoes and walk.⁵ They can also affect your self-esteem.²

Most people will have warts at some point in their life, but they tend to affect children and teenagers more than adults.⁶

Types of warts

Warts can appear anywhere on your skin and mucosa, like on your hands and knees.^1,3,5 They vary in appearance and may develop on their own or in clusters.⁶

There are different types of warts, depending on where they are and what they look like:^6–9

Common warts – warts on your fingers, hands, or knees. These warts are firm, rough and might look like a very small cauliflower. They’re usually only a few millimetres across and are greyish-white or light brown
Verrucae (plantar warts) – warts on your feet (soles) that might have tiny black dots in the centre. Verrucae can be painful, especially when you put weight on them. If you have a cluster of verrucae, they can fuse together and form mosaic warts
Plane warts (flat warts) – most common on your face and the backs of your hands. These warts are smooth, round, and slightly raised, with a flat top. They can be slightly brown, greyish-yellow or skin-coloured. You tend to have more than one at a time
Filiform warts – commonly found on your face or neck. These look a bit like a finger and sometimes have a stalk
Periungual warts – typically found around your fingernails or toenails. Like common warts, these have a cauliflower-like appearance

Genital warts are a type of wart on your genitals also caused by HPV.⁷ These are classed as a sexually transmitted infection and treated differently to the other types of warts, so we have dedicated a separate page to discussing genital warts, anal warts and genital warts treatments.⁷

When to see a GP

You shouldn’t normally need to see a GP for a wart or verruca, as a pharmacist can usually provide the help you need.³ But you should see a GP if:³

A growth on your skin is causing you concern
You have a wart or verruca that keeps coming back
You have a very large or painful wart or verruca
A wart or verruca bleeds or changes in appearance
You have a wart on your face or genitals

Are warts contagious?

HPV is contagious and so are warts.⁵ They can spread through direct, skin-to-skin contact.^5,6But they can also spread through indirect contact with contaminated objects, such as:^5,6

Towels
Shoes
Areas surrounding swimming pools
The floors of communal changing areas

The HPV virus can enter your skin through small cuts if your skin is damaged.⁸Then, once you have a wart it can spread to other parts of your body, for example, if you scratch it and then touch another part of your body.⁶

You’re more likely to get a wart or spread a wart to another part of your body if your skin is damaged or wet.^6,7 This is because HPV virus can enter your skin through small cuts and is more likely to infect moist skin.^6,7

How to treat warts

Typically, warts and verrucae clear up on their own without any treatment.^3,6,11 However, it can take up to two years for the virus to leave your system and the warts to disappear.^3,6,11 Though this can vary from person to person, and can take even longer in older children and adults.⁶

As warts tend to go away by themselves, treatment isn’t always recommended because it can be painful and cause adverse effects like:¹¹

Pain
Blistering
Infection
Scarring

This means, a lot of the time, the benefits of treatment don’t necessarily outweigh the downsides.^6,11 Especially because, sometimes, a wart can return following treatment.⁶However, there are some circumstances in which treatment may be worthwhile. For example, if your wart is:

Painful (e.g. On the soles of the feet or near a nail)
Not getting better after treatment
Causing you distress or embarrassment due to its position (e.g. On the face)

Common ways to treat warts and verrucae include:^3,6,11

Over-the-counter products

You can buy creams, gels, wart paints, wart and verruca freeze sprays and medicated plasters over the counter to treat warts and verrucae. Some of these treatments contain topical salicylic acid (most preparations are 12–26 %), which should be applied every day for up to 12 weeks. Over-the-counter products may irritate your skin, are not suitable for warts on your face and don’t always work.

Cryotherapy

If over-the-counter treatment has not worked or you have a wart on your face, your GP or a podiatrist may use liquid nitrogen to freeze spray a wart and destroy the affected skin cells. This procedure is called cryotherapy and is usually carried out every 2–4 weeks for six treatments or until the wart is gone.

How to prevent warts

To reduce your chances of getting warts or verrucae and prevent them spreading to others:^3,6,10

Keep your feet dry
Change your socks every day and do not share shocks with someone who has a verruca
Avoid scratching or picking a wart or verruca to prevent it from spreading
Wear gloves if you have a wart on your hand and need to share equipment
Wear shoes or flip flops around communal changing rooms and swimming pools
