What Is Bazuka Verruca Gel and How Does It Treat Warts?

 

Warts and verrucas are incredibly common. In fact, the NHS estimates that most people will develop at least one wart at some point in their lives. They are caused by the human papillomavirus (HPV), which triggers an overgrowth of skin cells, creating those familiar rough, raised lumps. Bazuka verruca gel is a trusted, over-the-counter topical treatment that targets this hardened skin directly, helping to remove warts and verrucas gradually with regular use. At just £6.21 for a 5g tube, it offers an accessible option for people who want to treat the problem at home without a GP appointment. You can browse our full range of foot care products if you are looking for additional support alongside your treatment.

The active ingredient is salicylic acid at a concentration of 26%. This is a well-established keratolytic agent — meaning it works by softening and dissolving the outer layers of thickened skin. It has been used in dermatology for decades and is recommended by the NHS as a first-line treatment for common warts and verrucas.

 

How Does Bazuka Verruca & Wart Gel Work on Skin?

 

The mechanism behind Bazuka is straightforward but clinically effective. Salicylic acid disrupts the bonds that hold dead skin cells together, allowing the thickened tissue overlying the wart to be gradually removed. Here is how the process works:

  • Salicylic acid penetrates the outer layer of skin (the stratum corneum) and breaks down keratin proteins.
  • This softens the hardened skin that forms over the wart or verruca.
  • The dead skin can then be filed away with an emery board, exposing the underlying tissue.
  • Repeated daily application gradually reduces the size of the wart until it is eliminated.

The gel formulation also creates a protective film over the treated area, which helps to keep the active ingredient in contact with the skin for longer. This is one reason why gel-based preparations are often preferred over liquid drops for verrucas on the sole of the foot, where pressure and movement can dislodge treatments quickly.

 

Who Should Use Bazuka Verruca & Wart Gel?

 

This product is suitable for a wide range of people dealing with common warts or verrucas. It is designed for topical use on the hands and feet and is appropriate for both adults and children aged 2 years and over. That said, it is not suitable for everyone.

  • Adults with common warts or verrucas on the hands or feet
  • Children aged 2 and over, under adult supervision
  • People looking for a convenient, at-home treatment option
  • Those who have not responded to simple filing and moisturising alone

It is not suitable for use on facial warts, genital warts, or warts with hair growing from them. People with diabetes, poor circulation, or peripheral neuropathy should speak to a doctor before using any salicylic acid product, as reduced sensation can mask skin damage.

Is Bazuka Verruca Gel Safe to Store at Home?

 

Yes — provided you follow a few simple precautions. The gel contains alcohol and is highly flammable, so it must be kept away from heat sources and naked flames. Store it below 25°C, out of direct sunlight, and always keep the cap tightly closed after use. Keep it out of reach of children, even though the product itself is suitable for use in children aged 2 and over. If you are also managing other skin conditions, our skin care collection includes a range of complementary products that may help support overall skin health during treatment.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Bazuka Verruca & Wart Gel 5g

 

What Is Bazuka Verruca & Wart Gel and What Is It Used For?

 

Bazuka Verruca & Wart Gel 5g is an over-the-counter topical medicine used to treat common warts and verrucas (also called plantar warts). It contains salicylic acid 26% w/w as its active ingredient. Warts are small, rough growths caused by certain strains of the human papillomavirus (HPV). Verrucas are simply warts that develop on the soles of the feet and are pushed inward by the pressure of walking, making them particularly uncomfortable. The NHS confirms that salicylic acid is one of the most widely recommended first-line treatments for these conditions.

 

What Do You Need to Know Before Using Bazuka Verruca & Wart Gel?

 

Before you start using this gel, it is important to check whether it is appropriate for you. Do not use Bazuka Verruca & Wart Gel if any of the following apply:

  • You are allergic to salicylic acid or any other ingredient in the gel
  • The wart is on your face, genitals, or anal area
  • The wart has hair growing from it
  • The skin around the wart is broken, inflamed, or infected
  • You have diabetes mellitus
  • You have poor blood circulation or peripheral vascular disease
  • You are treating a child under 2 years of age

There are no significant known drug interactions with topical salicylic acid at this concentration when used as directed. However, you should be aware of the following:

  • Avoid applying to healthy surrounding skin — use petroleum jelly (e.g. Vaseline) to protect the area around the wart
  • Do not use alongside other topical skin treatments on the same area without pharmacist advice
  • The gel is flammable — do not use near naked flames or heat sources

 

How Should You Use Bazuka Verruca & Wart Gel?

 

Consistent daily application is key to getting results. Follow these steps carefully each time you use the gel:

  1. Soak the affected area in warm water for 2–3 minutes to soften the skin.
  2. Dry the area thoroughly with a clean towel.
  3. Gently file away any loose or dead skin using an emery board or pumice stone. Dispose of the filing material after use — do not share it.
  4. Apply a thin layer of Bazuka gel directly to the wart or verruca only, using the applicator. Avoid contact with healthy surrounding skin.
  5. Allow the gel to dry completely — this usually takes a few minutes.
  6. Cover the treated area with a plaster or dressing.
  7. Repeat once daily, ideally at the same time each day.
Indication Age Group Dose Frequency
Common warts Adults & children 2+ Thin layer to wart only Once daily
Verrucas (plantar warts) Adults & children 2+ Thin layer to verruca only Once daily

If you are also dealing with fungal skin conditions on the feet, you may find our athletes foot and fungal infections range useful alongside your wart treatment.

 

What Are the Possible Side Effects of Bazuka Verruca & Wart Gel?

 

Like all medicines, Bazuka Verruca & Wart Gel can cause side effects, although not everyone will experience them. Most side effects are localised to the area of application and are mild.

Common side effects:

  • Mild skin irritation at the application site
  • Redness or soreness around the treated area
  • Temporary stinging or burning sensation on application

Less common side effects:

  • Blistering of the skin if the gel spreads to healthy tissue
  • Skin peeling beyond the treated area
  • Allergic skin reaction (rash, itching, swelling) — stop use immediately if this occurs

If you experience severe irritation, blistering, or signs of an allergic reaction, stop using the gel and seek advice from your pharmacist or GP. For minor first aid needs during treatment, our first aid collection includes plasters and wound dressings that can help protect the treated area.

 

How Should You Store Bazuka Verruca & Wart Gel?

 

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and heat sources
  • Keep away from naked flames — the gel is highly flammable
  • Always replace the cap tightly after use
  • Keep out of the reach and sight of children
  • Do not use after the expiry date printed on the tube
  • Do not dispose of medicines via wastewater or household waste — return unused product to your pharmacy

Frequently Asked Questions

Where can I buy Bazuka Verruca Gel online in the UK?

You can buy Bazuka Verruca & Wart Gel 5g directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £6.21. It is available without a prescription as it is classified as a General Sale List (GSL) medicine. No consultation is required — simply add it to your basket and it will be dispatched to your door.

How does Bazuka Verruca Gel work in the body?

Bazuka Verruca Gel contains 26% salicylic acid, a keratolytic agent that breaks down the keratin protein in the hardened skin overlying a wart or verruca. This softens the thickened tissue so it can be filed away, gradually reducing the size of the wart with each daily application. It does not directly kill the HPV virus but removes the infected skin cells layer by layer.

How do I use Bazuka Verruca Gel step by step?

Start by soaking the affected area in warm water for 2–3 minutes, then dry it thoroughly. Apply a thin layer of gel to the wart or verruca only — avoid healthy skin — and allow it to dry before covering with a plaster. Repeat this process once daily, filing away dead skin before each application using a disposable emery board.

How long does Bazuka Verruca Gel take to work?

Results vary depending on the size and depth of the wart or verruca, but the NHS advises that salicylic acid treatments can take up to 12 weeks of consistent daily use to be fully effective. Smaller, more superficial warts may respond more quickly. Patience and consistency are essential — missing applications will slow progress.

Can children use Bazuka Verruca Gel safely?

Yes — Bazuka Verruca Gel is suitable for children aged 2 years and over, but it must always be applied by or under the supervision of an adult. Care should be taken to avoid contact with healthy skin, eyes, and mouth. If you are unsure whether it is appropriate for your child, speak to your pharmacist before use.

What are the side effects of Bazuka Verruca Gel?

The most common side effects are mild skin irritation, redness, and a temporary stinging sensation at the application site. Less commonly, blistering or peeling may occur if the gel spreads to healthy surrounding skin. If you experience a severe reaction or signs of allergy such as swelling or widespread rash, stop use immediately and consult a pharmacist or GP.

Is Bazuka Verruca Gel safe for people with diabetes?

No — people with diabetes should not use Bazuka Verruca Gel without first consulting their doctor or pharmacist. Diabetes can cause reduced sensation and impaired healing in the feet, meaning skin damage from salicylic acid may go unnoticed and worsen. A healthcare professional can advise on safer alternatives for managing warts and verrucas in this group.

What is the best time of day to use Bazuka Verruca Gel?

There is no clinically specified time of day, but most people find it easiest to apply the gel in the evening after bathing or showering, when the skin is already softened. Applying at night also means the treated area can be covered with a plaster and left undisturbed for several hours. Consistency matters more than timing — pick a time you can stick to every day.

What happens if I miss a dose of Bazuka Verruca Gel?

If you miss a day, simply resume your normal application routine the following day — do not apply a double amount to compensate. Missing occasional applications will not cause harm, but it will slow down the overall treatment process. The NHS recommends consistent daily use for the best chance of clearing warts and verrucas with salicylic acid.

What are the alternatives to Bazuka Verruca Gel?

Alternatives include other salicylic acid-based products such as Wartner Wart & Verruca Gel, as well as over-the-counter cryotherapy sprays that freeze the wart tissue. For persistent or painful verrucas, your GP may refer you for professional cryotherapy or other treatments. You can explore our broader foot care range for additional options.

How long can you use Bazuka Verruca Gel for?

The gel can be used for up to 12 weeks. If the wart or verruca has not improved after this period, you should stop use and consult your GP or pharmacist for further advice. Continuing beyond 12 weeks without improvement is not recommended, as persistent warts may require a different treatment approach.

Can I use Bazuka Verruca Gel on my face?

No — Bazuka Verruca Gel must not be used on facial warts. The skin on the face is more sensitive and the high concentration of salicylic acid (26%) can cause significant irritation or chemical burns. Facial warts should be assessed by a GP or dermatologist, who can recommend appropriate treatment options.

Is Bazuka Verruca Gel suitable during pregnancy?

There is limited safety data on the use of topical salicylic acid at high concentrations during pregnancy. If you are pregnant or breastfeeding, you should speak to your GP or pharmacist before using Bazuka Verruca Gel. They can advise on whether the benefits outweigh any potential risks in your individual situation.

What are the latest studies on salicylic acid for verruca treatment?

Salicylic acid remains one of the most studied and evidence-supported treatments for warts and verrucas. A Cochrane review found that salicylic acid preparations showed a statistically significant benefit over placebo in clearing warts. The NHS continues to recommend it as a first-line treatment, reflecting its established safety and efficacy profile in clinical literature.

Who is not eligible to use Bazuka Verruca Gel?

You should not use this gel if you have diabetes, poor circulation, or peripheral neuropathy; if the wart is on your face or genitals; if the skin is broken or infected; or if you are allergic to salicylic acid. Children under 2 years of age should also not use this product. If you are unsure, our skin care collection includes alternative products that may be more suitable for sensitive skin types.

How Should You Use Bazuka Verruca & Wart Gel?

Using Bazuka Verruca & Wart Gel correctly makes a real difference to how quickly you see results. The gel should be applied once daily to the wart or verruca only, taking care to protect the healthy skin around it. Before each application, protect the surrounding skin by applying a small amount of petroleum jelly (such as Vaseline) to the area around — but not on — the wart.

Follow these steps each time you apply the gel:

What Is the Correct Dose of Bazuka Verruca & Wart Gel?

The correct dose is a thin layer of gel applied directly to the wart or verruca once daily. You should not apply more than a thin covering — using excess gel increases the risk of irritation to surrounding healthy skin without improving results. The table below summarises dosing by indication and age group.

When Is the Best Time to Use Bazuka Verruca & Wart Gel?

There is no single clinically mandated time of day, but most people find that applying the gel in the evening — after bathing or showering — works best. At this point the skin is already softened from warm water, which makes filing easier and helps the gel penetrate more effectively. Applying at night also means the plaster can remain in place undisturbed for several hours, maximising contact time between the salicylic acid and the wart tissue.

Whatever time you choose, consistency is what matters most. Try to apply the gel at the same time each day to build a routine and avoid missed applications, which can slow your progress.

How Long Can You Use Bazuka Verruca & Wart Gel For?

You can use Bazuka Verruca & Wart Gel for up to 12 weeks. The NHS advises that wart treatments using salicylic acid may take the full 12 weeks to produce results, particularly for larger or deeper verrucas. Do not be discouraged if you do not see immediate improvement — gradual reduction in size is a sign the treatment is working.

If the wart or verruca has not cleared after 12 weeks of consistent daily use, stop treatment and speak to your GP or pharmacist. They can assess whether a different approach — such as professional cryotherapy — would be more appropriate for your situation.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Bazuka Verruca & Wart Gel?

Most people who use Bazuka Verruca & Wart Gel tolerate it well, but some localised side effects can occur. These are generally mild and related to the keratolytic action of salicylic acid on the skin. Common side effects include:

  • Mild skin irritation at the site of application
  • Redness or soreness around the treated area
  • A temporary stinging or burning sensation immediately after applying the gel
  • Slight skin peeling or flaking as the dead skin is broken down

These effects are usually a sign that the treatment is working. They tend to be more noticeable in the first few days of use and often settle as your skin adjusts. Protecting the healthy skin around the wart with petroleum jelly before each application can help minimise irritation.

What Are the Less Common Side Effects of Bazuka Verruca & Wart Gel?

Less commonly, some people may experience more pronounced skin reactions, particularly if the gel comes into contact with healthy skin or is applied too liberally. Less common side effects include:

  • Blistering of the skin at or around the application site
  • Skin peeling extending beyond the treated area
  • Prolonged or worsening soreness that does not settle between applications
  • Discolouration of the skin around the wart

If you notice any of these effects, reduce the area of application and ensure you are only applying the gel to the wart itself. If symptoms persist, stop use and seek advice from your pharmacist.

What Are the Serious Side Effects of Bazuka Verruca & Wart Gel?

Serious side effects are rare when the gel is used as directed, but they can occur. You should stop using the gel immediately and seek medical attention if you experience any of the following:

  • Signs of an allergic reaction — including widespread rash, itching, swelling of the face, lips, or throat, or difficulty breathing
  • Severe chemical burn or deep blistering of the skin
  • Signs of skin infection at the treatment site — including increased warmth, pus, or spreading redness

Allergic reactions to salicylic acid are uncommon but possible. If you have previously reacted to aspirin or other salicylate-containing products, you may be at higher risk and should consult your pharmacist before use.

What Should You Do If You Experience Side Effects of Bazuka Verruca & Wart Gel?

For mild irritation, try reducing the frequency of application temporarily or ensuring you are protecting the surrounding skin more carefully. If side effects are moderate or worsening, stop use and speak to your pharmacist — they can advise on whether to continue, switch to an alternative treatment, or refer you to your GP. Do not attempt to treat blistered or broken skin with the gel.

In the event of accidental ingestion or eye contact, rinse thoroughly with water and seek immediate medical advice. Keep the product out of reach of children at all times.

Can Bazuka Verruca & Wart Gel Interact With Other Medicines?

There are no significant known drug interactions associated with topical salicylic acid at the concentration found in Bazuka Verruca & Wart Gel when used as directed on intact skin. However, you should avoid applying other topical skin treatments to the same area at the same time without first checking with your pharmacist, as this could increase the risk of skin irritation or alter the effectiveness of either product.

People taking oral anticoagulants such as warfarin should be aware that large-area application of high-concentration salicylic acid products is not recommended, though this is unlikely to be relevant when treating a small wart or verruca. If you are on any regular medication, it is always worth mentioning new treatments to your pharmacist.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
