Warts and verrucas - Treatment 

Treating warts and verrucas 

Warts usually clear up without treatment. However, it can take up to two years for the virus to leave your system and the warts to disappear.

The length of time it takes for a wart to disappear will vary from person to person. They tend to last longer in older children and adults.

In adults and people with a weakened immune system, warts are less likely to clear up on their own or respond well to treatment.

Leaving the wart to go away by itself is one option. However, you may want to consider treatment if your wart is painful, in an awkward position, or is causing you distress or embarrassment.

Your GP should always refer you to a specialist if you need treatment for a wart on your face.

Treatment options

There are a number of treatments available for warts. However, no single treatment is 100% effective, and the wart may return.

The aim of treatment is to remove the wart without it returning and without leaving any scarring.

Treatments include:

  • salicylic acid
  • cryotherapy
  • duct tape
  • chemical treatments

Surgery to treat warts is not usually recommended because warts often return and further treatment is required.

Some treatments may cause side effects such as mild pain, blistering and skin irritation around the wart.

These various treatments are described below.

Salicylic acid

Many wart and verruca treatments – including creams, gels, paints and medicated plasters – are available over the counter from pharmacies.

Salicylic acid is the active ingredient in most of these treatments. It has been shown that salicylic acid is as effective as cryotherapy for treating warts. 

There is limited evidence available to show which type of salicylic acid treatment (cream, gel, paint or plasters) is most effective.

Salicylic acid and other wart treatments also destroy healthy skin, so it is important to protect your skin before applying the treatment. You can use petroleum jelly or a corn plaster to cover the skin around the wart.

Before applying the treatment to your wart, use an emery board or pumice stone to file it down a little (avoid sharing the board or pumice stone with others). Repeat this about once a week while you are treating your warts.

Each time you treat your wart, soak it in water for about five minutes first to soften it, then follow the instructions that come with the medication.

You may need to apply the treatment every day for 12 weeks or longer. You should stop the treatment if your skin becomes sore, and seek advice from your GP or pharmacist.

Don't use treatments that contain salicylic acid to treat warts on your face. Ask your GP or pharmacist for advice about the best type of treatment.

Consult your GP before using over-the-counter treatments that contain salicylic acid if you have poor circulation  for example, if you have a condition like diabetes or peripheral arterial disease (PAD). This is because there is an increased risk of damage to your skin, nerves and tendons.


In cryotherapy, liquid nitrogen is applied to your wart for a few seconds to freeze and destroy the affected skin cells. After treatment, a sore blister will form, followed by a scab, which will fall off 7-10 days later.

A session of cryotherapy usually takes 5-15 minutes and can be painful. Large warts usually need to be frozen a few times before they clear up. You will probably need to wait a few weeks between each treatment.

There are two different cryotherapy methods. Liquid nitrogen may be sprayed directly onto the wart, or it may be applied using a stick with cotton wool on the tip. This second method is often preferred for treatment around the eyes or for small children.

Cryotherapy may be recommended if you have a wart on your face. This is because the risk of irritation is lower than when using salicylic acid or duct tape.

Cryotherapy is not usually recommended to treat young children because they may find the treatment too painful. It may also be difficult for them to stay in the same position while having the treatment.

If cryotherapy hasn't been successful within three months, further treatments aren't likely to be effective.

Possible side effects of cryotherapy include:

  • pain and blistering
  • your skin may become darker (hyperpigmentation) or lighter (hypopigmentation) – particularly if you have black skin
  • your nails may develop an abnormal change in shape or structure if cryotherapy is used to treat warts that develop around the nails (periungual warts)

Cryotherapy is sometimes carried out at GP surgeries or at hospital skincare clinics. However, it may not be available on the NHS in all areas of the country.

A very cold spray (dimethyl ether propane) is also available from pharmacies, which you can apply yourself. You should avoid using this spray on your face. Evidence suggests these sprays are not as effective as cryotherapy using liquid nitrogen.

Duct tape

Treatment with duct tape involves placing a piece of duct tape over your wart for about six days. If the tape falls off, simply replace it with a fresh piece. After six days, remove the tape and soak the wart in water.

After soaking the wart, use an emery board or pumice stone to get rid of any rough areas. Leave the wart uncovered overnight and apply a new piece of duct tape the following morning. This procedure should be repeated for a period of up to two months.

There is limited evidence to support the effectiveness of using duct tape to treat warts. However, side effects of this type of treatment are rare, although the skin can become irritated.

Chemical treatments

Warts can also be treated using chemical treatments available on prescription. The treatments contain chemicals such as:

These chemicals are applied to the warts to kill affected skin cells. Potential side effects include the skin being stained brown (with glutaraldehyde) and burns to the surrounding skin (with silver nitrate). 

Treating warts during pregnancy

If you are pregnant and have warts, your GP may recommend using salicylic acid, cryotherapy or duct tape.

Salicylic acid can be used to treat warts during pregnancy, as long as it is used on a small area for a limited period of time.

I went to see a NHS dermatologist and was given cryotherapy for a skin tag on my right buttock,even though i had known of an alternative natural treatment i had seen on Youtube which is meant to leave no scars.
I still went ahead and now regret going ahead with it as it has left me with a scar that is still even after almost 1 year.
I wish i had bought this natural treatment.
Anyone thinking of having cryotherapy for a skin tag,wart,think twice before you go ahead and try to google for natural treatments..
I opted for the NHS treatment as it was free,but looking back i will try this natural treatment if i get a new skin tag etc

I had two verrucas for fourteen years after having cancer and tried every over the counter product plus chiropodist treatment and they still persisted.Then in May this year I went on a diet to lose weight and cut out all cake ,desserts,chocolate biscuits etc.After a month my verrucas stopped growing and the skin on my feet which had been very dry started to improve.Four months on I have lost two stone,my verrucas are barely visible and my skin generally is much better.This may be a coincidence but worth trying.

Iv got 3 verrucas on the bottom of both of my feet and 1 corn on each small toe which iv had for 15 years, Which i was told it was corns and a the 3 verrucas are the size of a 10p coin. Tryed all the bazookas and the different acid available in pharmacys, in 2013 I went to 7 appointments at a foot clinic where they where spraying it then cutting it. I didn't receive a follow up appointment, when I called to find out they said I missed my appointment and I've been discharged and gp needs to refer me again. 2 years ago I started wrapping my feet in zinc oxide tape and sports tapes and the verrucas and corns drys and peels off but it grows back in a week. Last Wednesday I went to a appointment for cryotherapy and the doctor freezed my verrucas on my left foot, the next 3 days my left foot hurts like hell when I try to walk on it or stand on it or if the frozen area is touched...is cryotherapy treatments worth the pain? Will it go away?

My comment has been removed ? Anyway i had a verruca for ten years and tried everything mentioned and more including expensive podiatry visits.
What actually worked was Marigold Tagetes oil NOT Marigold Calendula.
It only took a few days for the verruca to dry up and i picked it out. I used bottles of freeze spray which i believe damaged the nerves.pretty useless in my case.
Like most of the other treatment here be careful, seek further advise and dont use on children.

A note for GoldenBorage and others.
Had verrucas for 10+ years - went to many GPs, dermatologists and chiropodists. Tried every kind of wartner, bazuka, cryogenic, even formaldehyde (which incidentally appears to just pickle the feet - what else is it expected to do???), you name it. Eventually the verrucas had spread to both feet and covered the balls of my feet almost entirely. When I finally found a wonderful podiatrist who really cared and was up for the challenge she photographed my feet as they were the worst she had ever seen and she wrote an article for a medical journal charting my journey to recovery. After some different treatments again she took me to a podiatry surgeon in Northampton. We waited 4 months for him to complete a tour of duty with the British Army in Iraq. He prescribed Tricetachloric acid. My podiatrist was incredulous as she thought it had been banned here for a long time. The podiatry surgeon reckoned the British Army uses this stuff all the time. Whatever......... 3 days (yes 3 days) after applying the treatment, we took the dressings off and took a look. The verrucas were gone and my feet had new skin like a baby's. Incredible! Fumigated all my shoes with a jar of cider vinegar and hey presto - Never had one since (10years later).

My point is dont give up! Try everything and if all else fails see if you can ask for Tricetachloric acid

cider vinegar and duct tape/waterproof plaster!
my daughter caught a wart probably from the swimming pool and i left it hoping it d go away by itself but it grew and became quite painful .
i first tried hand sanitizer as i saw it in this thread it didn't seem to do much.
I switched to cider vinegar and the result came really fast.The wart turned black within a week and off within another week. I did it on and off as she was a bit grumpy about it and also she kept loosing the plasters or duct tape .
I put a tiny ball of cotton in vinegar then placed on top of the verruca overnight with a waterproof plaster and in the morning replaced with duct tape for a couple of days then started again basically.
you have to be very careful not to put too much cider on the rest of the skin as it is quite aggressive.

Hand sanitiser is the answer! Ive had verrucas for years and tried everything. This works! Ive been taking off the dead skin every couple of days and putting on the hand sanitiser twice a day, great results after a week they look on their last legs. Definitely give it a try.

i had a warts on my face from november 2012 and had a treatment from GP for nearly 8 months but their is no good news. also contact the doctor in wellington hospital near lords cricket ground but it was so expensive to treat, dont even think about it per sitting £2000.00 pound and need to go for three to four sitting.

I consult the doctor in india and had a laser treatment two seatings in gap of two months and fantastic result no sign of warts on my face. costing around £200.00 pound per sittings.
don't waste your time behind GP as NHS doesnot cover the laser treatment.

I would like to thank anyone who suggested the use of hand sanitiser to treat a verruca.

I noticed one appeared earlier this year so immediately went out and bought Wartner. After 2 treatments, it was still there. Since then, I've just tried covering it up with water-proof plasters to avoiding passing it on to others and try to let it go by itself. The stubborn thing would not budge.

After a false alarm where I thought warts were spreading to my fingers, I searched the Internet for any alternative treatments and came across the suggestion of using a pumice stone (to file away the hard skin) hand sanitiser. It took 3-4 days for me to notice the improvement. Basically after soaking my foot and filing on day 4, I noticed that most of the black specks had gone - they previously bled when I picked at the hard skin. Now, less than a week later, there are no more black specks. I'm going to keep using this treatment for a little longer to make sure it clears fully.

My recommendation is to try filing and hand sanitiser before wasting money on expensive treatments. However, I would suggest to be careful when filing and soaking your foot to make sure you don't pass the virus on to others or other parts of your own foot.

I had one verruca on the right foot in early 2009. For two years, I did not treat it in view of the NHS advice that warts and verrucas go away on their own. By early 2012, this advice had proved untrue. I had 9 verrucas spread on both feet, 2 of which where particularly large (1cm each), a new small wart on my thumb and 3 ano-genital warts. The NHS said that warts at different locations were unrelated types of HPV, it however seems a strange coincidence.

By this time, I felt great distress. I tried over the counter medecines, which inflammated my skin and caused bleeding.

Despite the above website saying that a GP can be consulted and treated by cryotherapy if the warts/verrucas cause distress or discomfort, I saw two different GPs who said they did not treat patients with such condition, appart from the ano-genital ones which disappeared after only one cryo treatment.

I paid for 2 private cryotherapy treatments (all I could financially afford at the time) and only the two big verrucas on my feet remained. Two months later, I had 10 new ones on top of the other 2, at different locations than the previous ones. I paid for a further 2 cryo treatments and they reduced to 5 in total. By this time my spirits were crushed. I saw a 3rd GP and broke into tears. She was particularly rude and insensitive to my distress and dismissed me awfully badly saying nothing could be done. A month later I received a letter saying I had an NHS appointment for cryo.

The NHS cryo doctor, was extremely sympathetic and treated my wounds in such a delicate manner that neither pain, blistering nor bleeding occurred. My private cryo treatments (Shuropody) always caused pain, bleeding and blistering. Also the NHS doctor was explaining exactly what I had, while the shuropody one seemed not to know much about details of HPV.

I now have again new ones. I prefer to keep trying rather than let them contaminate the rest of my sole and grow to unmanageable sizes.

I've had warts for 10 years now, I've tried leaving them alone (they multiplied), acid paint which turned them white and painful and I am currently in a course of cryotherapy but I've been told I'm only allowed six treatments and I've been made to feel like I've wasted NHS time seeing my doctor about them and I've been given no hope of ever getting rid of them :( I even tried hand gel which didn't work, I will be combining the freezing with duct tape but can only do that on my foot. It's annoying, I can't go swimming and people don't want me around despite me telling them its benign and of little risk to them.

I had warts when I was a child and the only thing that got rid of them was the sulpher of a match. I have been suffering with verruccas for 6 years and just recently warts appeared on my fingers. I have tried all the treatments and even the chiropodist didn't manage to rid them permanently. I started taking vitamin c with Zinc maybe about 10 months now and I must say for the first time I have never as good. The dam things have all gone. It could be worth trying.

I had a number of warts on both hands for 5 years plus lots of foot veruccas and found the following treatments have worked well for me.

Warts: I originally tried 2 over-the-counter freeze treatments (2 different brands) but found them absolutely useless.

I then treated the warts on a daily basis with an over- the-counter salicylic acid gel (I used the extra strength one). I only missed the odd day here and there but it has taken 4 months of daily treatment to reduce the warts from 8 largish ones to 1 which is barely visible. For the veruccas I covered them with duct tape night & day for 2 weeks then followed the following method: duct tape on during the day, then soaked the feet in water in the evening, rubbed the verrucas with a foot file, then applied tea tree oil and left uncovered overnight. Covered over with duct tape every morning.

I did this daily for about 3 months and although I noticed a good improvement it didn't seem to shift them totally. I then tried using hand sanitiser gel & 'fingers crossed' this seems to have shifted all but one of the veruccas. I'll keep going until they've all gone.

My advice to anyone is to just keep going with a treatment and to apply it everyday. I thought about giving up several times as the little blighters didn't disappear very quickly. But I'm glad I persevered as I've seen some great results.

I have to say that both myself and my sister have always had problems with Warts and myself have had the old verruca now and again.

we are both adults now but i have slowly been able to get rid of them one by one - the last two i have was a big wart on my hand1.5 cm which after many times of picking and counter treatments finally went but it would be raw and weeping blood before the nuqleus seems to have died and health skin started growing back underneith it. i can still see the scar.

However i during this time i have also had picked up a verrruca on the outside rim of my foot which caused pain when too much of the rough skin had formed i could always remove that after a shower, but the core was always too embeded and i had tried every over the counter style proudct you can find in a chemist.

However after giving hand sanitiser a go after reading the above it has work really well - without any scientific testing, at worst it seems to have stoped the excess hard skin forming so i can get ot the core of the wart and at best it seems to have started killing off the virus/core as well- the skin is now flexible around and beneth and only a few back specs are visable as well as feeling from the , hopefully victory is around the corner as i havent been HPV free in decades!!!

all I have been doing is after another digout so i have a little bit exposed is to rough the area up with a pumice stone either after a shower or bath and rub in a small amount of sanitizer. the area started reducing and ive steped this up to twice a day last week and becaus there is no drying period or complcated prep it has been really easy to do it each and every day. Not leting up now victory is soo close!

I had a terrible verruca on my right foot for four years, (about the size of a fifty pence), which was starting to spread. I desperately paid for surgery on it twice, alas to no avail, it kept coming back. It was very painful and ugly, i didnt go swimming for years or take my socks of anywhere!

Eventually I started using athletes foot powder in my shoes and slippers and it worked wonders on the damn thing! I put copious ammounts into my slippers particularly after showering and in all my socks as well. Within two months the verruca dried right up and shrivelled, and surprisingly quickly, healthy skin started to grow in its place.

Definitely try athletes foot powder!!! Its much cheaper than two rounds of painful surgery!

Thank you very for Hand sanitiser post. That was the end to my year long suffering from 2 painful varrucas on my right foot. Daily morning, painful varruca on the heel used to obstruct my daily routine work. I tried all the suggested treatment available over the counter such as freezing, bazuka ,tea tree oil and duct tape in last 1 year. Utimate,easily available cheap and simple treatment applying hand sanitiser helped me. I dont have any pain since i applied hand sanitiser, i will use this for some time till i am sure about complete removal of varruca.
Thank you again for such useful post.

I tried hand sanitiser on my son's two verrucas after reading one of the above posts. Salicylic acid was having little effect after about 6 weeks and was uncomfortable for him. The hand sanitiser was a bit of a long shot but one verruca cleared up within two days and the other within a week. I'm keeping an eye out to see if they return but so far it seems to have been very effective.

I've had a cluster with one main on on side of toe for 6 years or more. No salycilic acid or freezing has had any effect at all (even after limping for a week from the treatment). I have tried duct tape - it might have worked on some of them but when I pull the skin there still seem to be paler patches there - not become worse since I gave up the tape about 4 months back. I'd like try the glutaraldehyde - has anyone tried it? I'd be really pleased if someone came up with a treatment - is there a resistant strain?

I have had a large verruca on my heel for approx 3 years now. Despite spending large amounts if money on over the counter verruca gels, freeze sprays, ointments and seeking medical help from my GP and chiropodist... The verruca remains. I have suffered extreme pain whilst trying to get rid of this painful damn nuisance. I find it extremely difficult to walk at time and feel like I'm just meant to have it forever! I have been told that the reason it is causing me so much pain is that the verruca itself has a nerve running right the way through the core of it! This is why I'm suffering yet no one seems to be able to help. I have children and cannot go swimming with them. I love going to the gym but many days I can't even put weight on my foot because of it. I'm due to go on holiday soon and I know I won't be able to wear any nice sandals or flip flops because of how unsightly the verruca is. Am I just destined to have this thing growing on my heel always? Quite possibly :(

I was having difficulty trying to get rid of my daughter's various verrucas on the soles of her feet and as her school would have a term of swimming the recommendation was for anyone with verrucas to wear swimming socks which are made of rubber. I struggled with putting these socks on so I would coat the inside with talcum powder which made it easier to slip on to her feet but the added bonus was that after doing this for a couple of weeks I noticed her verrucas had all virtually disappeared!!

After a number of attempts the liquid nitrogen treatment seemed to work for me. Or at least it seemed to alert my immune system to the fact there was a virus on the sole of my foot in regards to the verruca. I had a 1cm verruca with little black spots in it.

The freezing treatment comes in drops of the liquid directly onto the verruca and then leaving it to work over a week or so. In my case I saw little happening after 4 or 5 treatments - more than recommended (and I used much more than the recommended dose).

A blister did not form and it did not fall off gradually. It took about an extra six weeks after I finished the treatment for the verruca to fully disappear, but the pain stopped after about 2 weeks after the fifth treatment.

I think it's a weak product purposefully. All in all it's pretty long winded and slow but it gets there in the end. I also tried the salicylic acid but it didn't do anything but kill skin.

My daughter has got a wart on her elbow ( she is 7), a couple of weeks ago, it seemed to open up and there was a cm long piece of skin sticking out. Since then have been to gp who says that they dont do anything for warts and it will go on its on, but last few days it has started to bleed a few time, sometimes with being knocked other times just by bending her arm!!!!

Is there nothing I can do, it bleed quite a lot and most nights we cover it so that it doesnt get caught on her bedding.

I had a cluster of veruccas on my left foot for over a year, maybe even 18 months. I tried everything from going to a chiropodist, using banana peels, vinegar + duct tape, bazuka gel etc. and none of them worked.

I basically just gave up and would only take away the hard skin around that area when it was starting to get a little uncomfortable, thickening of the skin that I'm sure a few of you can relate to.

Now it may have just cleared up over time, but I started using one of those hand sanitiser gels around the area each time after I'd clear away some of the hard skin and I really think it helped. It may have prevented the cycle of spreading the verucca virus when clearing the hard skin away with my "corn & callous file". And the gel has the advantage of drying up quickly so the area wasn't left damp (something that I've read helps the virus spread).

I'd definitely recommend giving it a go, the hand sanitiser gels are pretty cheap and you certainly won't damage your feet using it.

I had cryotherapy yesterday on a small cluster of verrucas on the sole (heel) of my foot. It hurt a bit (not too much) during application, but today it's turned into a big, very sensitive blister which I can't put any weight on at all.

I was told it would likely hurt just for the rest of the day, but It's quite clear to me now that I'll be limping on tip toes on that foot for a good few days, even maybe a week. I would not recommend it unless you've tried absolutely everything else. I'll be cancelling my next session and trying the tape method next.

That said, the missus had cryo on small warts on her feet and it worked a treat after only one go. Perhaps it's just on the sole that it's not a good idea.

I had a verruca on my foot for years and probably picked it up swimming. I was told it would probably just go after a couple of years but 8 years later it was pretty large, about 15-20mm diameter.

Having kids made me want to get rid of it since I didn't want to spread it to them (though it has never even made it across to my right foot).

I tried everything. Salic acid - very little effect. Home freeze kits - very little effect.

In the end I went to my GP and got cryotherapy. It hurt! And what's more, it hurt so much to walk afterwards that I had to use a walking stick for days to avoid hurting my back because I was limping so much. I thought if it worked, I could take the pain. It didn't work!

In the end I tried the duct tape thing. There is some good research behind it - http://archpedi.ama-assn.org/cgi/content/full/156/10/971

I guess there are lots of chemical companies who don't want you to believe this works so they can sell you their products but it worked extremely well.

I bought some tough duct tape (called 'bear tape' in the US) and put a little Salicylic acid on first, then a big patch of duct tape, and left it on for a week (I even swam without it coming off).

At the end of the week the skin under the duct tape looked a bit grim (well it looked dead and nasty). I stuck with it, repeated the procedure over several weeks and one day i took the duct tape off, let the skin recover over night as per instructions on the NHS page above and I had completely killed it. It has turned out to be an incredible effective and pain free treatment.

Duct tape certainly worked very well for me and is much much cheaper than a home freeze kit.

I had a 5mm diameter wart on my right thumb, about 10mm from my nail. I tried using salicylic acid treatment for a number of weeks but each time the top layer was removed it bled profusely, and I became concerned that this would promote it to spread. Yesterday I had freezing treatment, and have a 3cm blood-filled blister encompassing most of my thumb, which is so painful I can't bend it. I spoke to a friend who has had this done in the US, and the doctor used a cone of the appropriate gauge for his wart to protect the surrounding healthy tissue. My GP used about 0.5mm Vaseline haphazardly applied near to the wart, which did absolutely nothing. I now have to attend a minor injuries clinic to have the frankly enormous blister dressed and treated. Was my GP untrained how to administer this treatment, or was the Practice to lazy or cheap to purchase the nozzle cones? Destroying this amount of tissue for a tiny wart is surely wrong - what ever happened to "First do no harm"?

How I cured my hand warts:

100% (not one per-cent) tea tree oil applied four times every day using a cotton bud - if you miss a day they come back and so only reduce once you are sure they are going.

Scraping of warts on hand skin and cutting of warts with nail clippers between the webs of the fingers (painful and self-damaging - entirely at your own risk) was necessary for me, very unfortunately as doing this is so painful.

I can not take any responsibility whatsoever for anybody following my steps to either treat themselves, or any others.

Please only try sensible things and if they don't work then stop. Don't eat or drink anything strange - this may harm you.

I hope this information might help somebody, since warts are so distressful.

Best wishes,

I have had several liquid nitrogen treatents of verrucas.
In no case has the blister detached.
On my GP's advice I use an abrasive stick to abrade the blister. This can take a few weeks. I found it impossible to judge how much to abrade the blister at any one session. It seems very "hit and miss"
Is there any advice on "how much abrasion, how judge, how often" ?

Swimming advice

If you or your child has a wart or verruca, going swimming is fine as long as you take steps to prevent the spread of infection.

You can put a waterproof plaster over the wart or verruca. Special rubber verruca socks are also available from pharmacies.

Wearing pool slippers or flip-flops around swimming pools and in communal changing areas will also reduce the risk of getting verrucas or passing them on to others.
