Warticon UK: Podophyllotoxin for Genital Warts — How It Works, Application & Results
A clinically reviewed guide to Warticon (podophyllotoxin) — how it works, cream vs solution, the treatment course, side effects, comparison with Aldara, and how to get a prescription online.
When to get urgent help: Call 999 or go to A&E if you have a serious allergic reaction (swollen lips, face or tongue, difficulty breathing). Contact NHS 111 or your GP (same day if possible) if Warticon causes open sores, bleeding, or severe pain or swelling that does not settle after washing it off, it gets in your eyes, or a lump bleeds, changes quickly or is inside the vagina or anus. Sexual health clinics offer free, confidential STI care – no GP registration needed.
▶ What is Warticon?
Warticon is a prescription-only topical treatment for external genital warts, containing podophyllotoxin — a plant-derived antimitotic agent. Available as Warticon 0.15% cream and Warticon 0.5% solution. It clears visible wart tissue by preventing HPV-infected cells from dividing. Most people see clearance within 4 weeks of completing up to 4 treatment cycles. GPhC pharmacy #9011198.
Genital warts are one of the most common sexually transmitted infections in the UK, caused by certain strains of Human Papillomavirus (HPV). They are highly contagious and spread through skin-to-skin sexual contact. Warticon is one of the most widely prescribed first-line treatments — effective, straightforward to use at home, and available online following a clinical consultation. This guide covers everything you need to know about using it correctly.

Start Your Consultation →What Is Warticon?
Warticon contains podophyllotoxin — a natural extract derived from the Podophyllum plant that stops wart cells dividing. It is specifically licensed for external genital warts: on the foreskin of the penis in men, and on the external vaginal area in women. It is not suitable for warts inside the vagina, urethra, or rectum.
HPV facts: Around 1 in 10 people develop genital warts at some point in their lives. Most HPV infections clear without treatment, but some strains cause visible warts that require management. The NHS HPV vaccine (offered to young people aged 12 to 13) protects against the strains most commonly responsible.

How Podophyllotoxin Works
Podophyllotoxin targets HPV-infected cells with precision. It disrupts the process of cell division within wart tissue, preventing the abnormal cells from replicating. This causes the infected tissue to break down and be shed gradually from the skin surface over the treatment course.
Warticon treats the visible warts but does not eradicate the underlying HPV virus. The virus may remain dormant in surrounding skin, which means warts can recur after successful treatment. This is why follow-up sexual health checks and continued use of condoms are recommended after completing a course.
Cream vs Solution: Which Should You Choose?
| Feature | Warticon 0.15% Cream | Warticon 0.5% Solution |
|---|---|---|
| Podophyllotoxin concentration | 0.15% | 0.5% |
| Appearance | White cream | Blue solution (may stain temporarily) |
| Application method | Fingertip — no applicator needed | Included applicator sticks (loop end for small warts; spatula end for larger) |
| Best for | Larger or widespread wart areas; easier self-application | Individual smaller warts; marginally higher efficacy per some evidence |
| Flammable? | No | Yes — store away from flames and heat |
| Relative effectiveness | Clinically effective | Marginally more effective in some trials |
Both formulations are clinically effective. The choice depends primarily on wart size, distribution, and personal preference. Your prescriber will recommend the most appropriate formulation during the online consultation.
How to Apply Warticon: Step-by-Step
Applying Warticon Cream (0.15%)
1
Wash and dry the area
Wash the affected area with mild soap and water. Pat dry thoroughly with a clean towel before applying.
2
Apply directly to each wart
Use a fingertip to apply a small amount of cream directly onto each wart. A mirror may help you see the area clearly.
3
Cover the wart only
Apply just enough to cover each wart. Do not allow cream to contact surrounding healthy skin — if it does, wash off immediately with soap and water.
4
Allow to dry
Let the cream dry completely before dressing or putting on underwear.
5
Wash hands
Wash your hands thoroughly after every application.
Applying Warticon Solution (0.5%)
1
Wash and dry the area
Wash the affected area gently with soap and water and dry thoroughly.
2
Use a new applicator for each application
Do not reuse applicator sticks between sessions.
3
Choose the correct end
Use the loop end for small individual warts. Use the spatula end for larger warts or clusters.
4
Apply to the wart only
Apply just enough solution to cover the wart surface. Avoid contact with healthy surrounding skin.
5
Allow to dry completely
Wait until fully dry before dressing.
6
Secure the cap and store safely
The solution is flammable — replace the cap firmly and store away from naked flames, heat, and children.
Important application notes: Do not apply to open wounds, cuts, or broken skin. Do not apply more frequently or in greater quantities than prescribed — this does not improve results and increases side effect risk. You do not need to cover treated areas with a dressing. Avoid unprotected sexual contact shortly after application.
Treatment Course and Timing
| Detail | Instruction |
|---|---|
| Frequency | Twice daily (morning and evening, roughly 12 hours apart) |
| Days on per cycle | 3 consecutive days |
| Break between cycles | 4 days off (no application) |
| One complete cycle | 3 days on + 4 days off = 7 days |
| Maximum cycles | 4 (28 days total) |
| If warts persist after 4 cycles | Do not repeat — consult your GP or sexual health clinic |
Many people see significant wart reduction after 1–2 cycles. Do not exceed 4 complete cycles. If the full course does not clear the warts, in-clinic treatments such as cryotherapy or surgical removal may be more appropriate.
Side Effects
Local skin reactions are the most common side effects of Warticon, typically occurring from the second or third day of each treatment period. They usually improve during the 4-day break between cycles.
| Side effect | How common | What to do |
|---|---|---|
| Local burning, stinging, or mild pain at the application site | Very common | Usually settles during the break period. Ensure cream or solution is applied to warts only. |
| Redness, irritation, or itching | Common | Expected; monitor. If severe, contact your prescriber. |
| Erosion or ulceration at application site | Uncommon | Stop treatment and contact your prescriber. |
| Blue staining of skin (solution only) | Common (temporary) | Normal; resolves after stopping treatment. |
Stop Warticon immediately and seek urgent medical advice if you experience: severe burning or intense pain not settling after washing off · heavy bleeding or significant blistering · widespread irritation spreading beyond the treated area. Wash the product off immediately with soap and water and call 111 or attend your nearest urgent treatment centre. In an emergency, call 999.
Who Cannot Use Warticon
- Pregnancy — podophyllotoxin is absorbed through the skin and may cause foetal harm. Do not use if pregnant or trying to conceive.
- Breastfeeding — may pass into breast milk; discuss alternatives with your prescriber.
- Internal warts — not licensed for warts inside the vagina, urethra, rectum, or anus. These require in-clinic treatment.
- Broken, inflamed, or infected skin — do not apply to skin that is not intact at the treatment site.
- Children — Warticon is for adult use only.
Warticon vs Aldara (Imiquimod): How They Compare
Two topical treatments are available for genital warts in the UK: Warticon (podophyllotoxin) and Aldara (imiquimod). They work through fundamentally different mechanisms.
| Feature | Warticon (podophyllotoxin) | Aldara (imiquimod 5%) |
|---|---|---|
| Mechanism | Directly destroys wart tissue by preventing cell division | Immune response modifier — stimulates local immune system to attack HPV-infected tissue |
| Speed of clearance | Faster — typically up to 4 weeks | Slower — up to 16 weeks |
| Recurrence prevention | Lower (does not address underlying immune response) | Higher — immune stimulation reduces recurrence risk |
| Treatment schedule | Twice daily, 3 days on / 4 days off, maximum 4 cycles | Three times weekly for up to 16 weeks |
| Relative cost | Generally lower | Generally higher |
| Best for | First-line treatment; fast clearance needed | Recurrent warts; or where Warticon has not cleared warts fully |
Neither is universally superior — choice depends on wart characteristics, treatment history, and patient preference. Your prescriber will recommend the most appropriate option during the consultation.
UK safety and prescribing information
Key UK rules for using Warticon safely, alongside the advice above.
- UK legal status: Warticon cream (0.15%) and solution (0.5%) are prescription-only medicines (POM). Safety has not been established in under-18s, so they are prescribed for adults. Access Doctor supplies MHRA-licensed UK medicines, dispensed by a GPhC-registered pharmacy (#9011198) after a prescriber’s assessment. It is illegal to sell or supply prescription-only medicines without a prescription in the UK.
- Treatment limits: twice daily for 3 days, then 4 days off, for no more than 4 weeks in total. If the area to be treated is larger than 4 cm², treatment should be supervised by a healthcare professional. Do not use on open or bleeding wounds or with other podophyllotoxin products.
- Internal and anal warts: do not use Warticon inside the vagina, urethra or back passage, or around the anus, unless a clinician has told you to — these warts are usually treated at a sexual health clinic.
Pregnancy and breastfeeding: Warticon must not be used in pregnancy or while breastfeeding, and women who could become pregnant should use reliable contraception during treatment. Genital warts in pregnancy are usually treated in a sexual health clinic, for example with freezing (cryotherapy) — speak to your midwife, GP or clinic.
- Free NHS treatment: genital warts can be diagnosed and treated free and confidentially at NHS sexual health clinics, without GP registration. A full STI check is recommended at the same time.
- HPV vaccination: the NHS offers the HPV vaccine to children aged 12 to 13, and to gay, bisexual and other men who have sex with men up to age 45 through sexual health clinics. It protects against HPV types 6 and 11, which cause most genital warts.
- Prescription charges: NHS prescription charges apply in England unless you are exempt; prescriptions are free in Scotland, Wales and Northern Ireland.

View Genital Warts Treatments →Frequently Asked Questions
What is Warticon and what does it treat?
Warticon is a prescription-only topical treatment for external genital warts, containing podophyllotoxin — a plant-derived antimitotic agent. Available as Warticon 0.15% cream and Warticon 0.5% solution. Licensed for external warts on the penis (foreskin) and external vaginal area. Not suitable for internal warts.
How does Warticon (podophyllotoxin) work?
Podophyllotoxin disrupts cell division in HPV-infected wart tissue, preventing replication. The infected tissue breaks down and sheds over the treatment course. It clears visible wart tissue but does not eradicate the underlying HPV virus, which may remain dormant.
How long does Warticon take to work?
Most people see clearance within 4 weeks of completing up to 4 treatment cycles (3 days on, 4 days off per cycle). If warts persist after 4 complete cycles, consult your GP or a sexual health clinic — do not repeat the course.
What is the difference between Warticon cream and Warticon solution?
Both contain podophyllotoxin. The cream (0.15%) is easier to apply by fingertip and better for larger or widespread areas. The solution (0.5%) has a higher concentration, uses applicator sticks, is blue-coloured (may temporarily stain), and is flammable. The solution is marginally more effective per some evidence.
Can I have sex while using Warticon?
Avoid unprotected sex shortly after application — there is a risk of transferring the treatment to a partner. Genital warts spread through skin-to-skin sexual contact. Condoms reduce transmission risk but do not provide complete protection against HPV.
Is Warticon or Aldara better for genital warts?
Warticon works faster (typically 4 weeks vs up to 16 weeks for Aldara) and is generally lower cost. Aldara stimulates the immune system and is more effective at preventing recurrence. Your prescriber will advise based on your clinical situation, wart history, and preference.
Who cannot use Warticon?
Warticon is not suitable during pregnancy or breastfeeding, for internal warts, on broken or infected skin, or in children. A clinical consultation screens for these contraindications before a prescription is issued.
Can I get genital warts treated free on the NHS?
Yes. NHS sexual health clinics diagnose and treat genital warts free of charge and in confidence, and you do not need to be registered with a GP. Treatment may include creams such as podophyllotoxin or imiquimod, or freezing (cryotherapy) in the clinic. If a GP prescribes treatment instead, prescription charges apply in England unless you are exempt.
