Frequently asked questions

Yes, apart from common warts, a range of wart types have been identified, varying in shape and site affected, as well as the type of human papillomavirus involved. These include:

Common warts (Verruca vulgaris): These are discrete, flesh-coloured papules, with a rough surface. They may be single or multiple and occasionally can be quite large. They are most common on the hands, but may occur anywhere. They are usually relatively easy to treat.

Plantar warts (Verruca, Verruca pedis): These are discrete and only just raised, having a roughened surface. They can occur on the palm but usually found on the sole, where they penetrate deeply because of the pressure of the body weight and are most difficult to treat. They may be quite painful and can interfere with walking. Minute haemorrhages may occur within them due to trombosed capillaries, which is visible by multiple black specks in the centre. They are usually found on pressure points on the soles of the feet.

Plane warts (Verruca plana): These are small, smooth flattened warts, flesh-coloured, which can occur in large numbers. They can occur everywhere, bust most particularly on the face, neck, hands, wrists and knees. They are quite frequently misdiagnosed, particularly on the face. They often occur in lines corresponding to a scratch or other such trauma.

Filiform or digitate wart: A thread or finger like wart, most common on the face, especially near the eyelids and lips.

Genital wart (venereal wart, Condyloma acuminatum, Verruca acuminata): They occur on the genital area.

Mosaic wart: A group of tightly clustered plantar-type warts, commonly on the hands or soles of the feet.

Periungual wart: A cauliflower-like cluster of warts that occurs around the nails.

• The appearance of a blister: this blister will disappear as soon as the wart or verruca falls off the skin. New skin will already have formed under the blister.
• Discomfort during use: a stinging sensation may occur when the gel formulation is left on the skin. This stinging sensation will fade within 10-15 minutes after application.
• Scars and nerve damage: this will only occur from careless use caused by not following the instructions on the information leaflet. Never use Wartner Wart Pen Wart Pen on healthy tissue, as TCA is a highly corrosive agent that will damage normal skin.
• In case the wart is very small and the treatment is maintained too long or too frequent, TCA may cause peeling of the deeper layers of the skin. If that occurs, the treatment should be immediately stopped. Thanks to natural regenerative properties of the skin- this damage is not permanent- a new & healthy skin will form instead.

Hold the pen vertically with the brush tip facing downwards. Slowly turn/click the dial on the top of the Pen clockwise to dispense the gel.

Allow the gel to flow into the brush tip for 3 to 5 seconds

Carefully apply the dispensed gel only on the wart or verruca (not on healthy skin surrounding it)

Let the gel dry for 10-15 minutes before putting on clothes or shoes.The Wartner Pen formula is very concentrated and only one drop is needed per application. Carefully cover the entire surface of the wart (or verruca) and not the healthy skin surrounding it. Once the treatment is completed, carefully clean the pen with a tissue before storage.

2 ADDITIONAL STEPS FOR VERRUCAS for optimal preparation and after-treatment

After applying the TCA gel and let it dry for 10-15 minutes, you could experience some discomfort when pressure or friction occurs on the treated area. You may find it helpful to protect the sensitive area with a comfort plaster which is widely available for purchase. Comfort pads not included.

• When applied, the TCA peeling effect appears immediately. The peeling effect remains longer after application compared to other acid treatments
• The effects (keratinisation and peeling off the skin) are visible soon after the first round of treatment (4 days with 2 daily applications).
• SPCs of traditional OTC wart & verruca treatments based on salicylic acid tend to indicate daily usage and a treatment time of up to 12 weeks.
• According to a pooled-analysis of 16 different clinical trials assessing the efficacy of salicylic acid treatments, the mean cure rate with salicylic acid treatment for removal of warts is 52%. In the same pooled analysis, it is recommended for trials to follow-up at a period of 12 weeks.
• Another controlled trial assessing the efficacy on warts of a treatment with salicylic acid (40%) applied during 13 weeks showed a cure rate of 24%, wheareas Wartner Wart Pen offers a complete removal up to 65% of treated warts & verrucas only after 4 weeks.

• 89% of patients tested were (very) satisfied with the convenience of the Pen
• 94% of patients tested were (very) satisfied with the efficacy of the Pen
• 82% of all patients tested prefer Wartner Wart Pen over their current treatment

• For removing warts on the face or on the genitals;
• For treating skin conditions with signs of inflammation;
• For removing dark moles, dark-colored, hairy or otherwise unusual looking skin conditions which resemble warts;
• For removing warts on children under the age of four.
• If the common wart or verruca is located in a sensitive area with thin skin (e.g. the face, neck, armpits, chin, breast) or on genital warts.
• If the nearby or affected skin is inflamed.
• If you are not certain that the skin condition you are treating is a common wart or verruca.
• Consult a doctor if you are diabetic.
• Consult a doctor if you are pregnant or breast-feeding.

• White coloration of the skin: as soon as you press the foam applicator onto the problem area, the skin turns white. This discoloration quickly decreases as soon as the foam applicator is removed.
• The appearance of a blister: this blister will disappear as soon as the wart or verruca falls off the skin. New skin will already have formed under the blister.
• Discomfort during use: a stinging sensation may occur when the foam applicator is pressed onto the skin. This stinging sensation quickly fades once the foam applicator is removed.
• Local tissue death: this will only occur during deep freezing of the skin. Therefore, never hold the foam applicator on a wart for more than 20 seconds (40 seconds for verrucas)
• Scars and nerve damage: this will only occur from careless use caused by not following the instructions on the information leaflet. Never hold the foam applicator on the wart for more than 20 seconds (40 seconds for verrucas) to ensure that there is no deep freezing and therefore no damage.

• As with all freezing methods, the skin may turn white temporarily.
• A blister develops under the wart, but this is part of the treatment and is harmless.
• Using Wartner Wart & Verruca Remover may cause some discomfort.
• Applying the foam applicator to the wart or verruca for too long may lead to local tissue death. You should therefore follow the instructions carefully and apply the treatment for the time specified based on the size of the wart or verruca.
• Always use Wartner Wart & Verruca Remover very carefully and accurately. If you’re not careful, scars and nerve damage may occur.

• If you are diabetic.
• If you are pregnant.
• If the common wart or verruca is located in a sensitive area with thin skin (e.g. the face, neck, armpits, chin, breast) or on genital warts.
• If the nearby or affected skin is inflamed.
• If you are not certain that the skin condition you are treating is a common wart or verruca.
• Wartner Wart & Verruca Remover should not be used on children under the age of four.

• Wartner Wart & Verruca Remover may not be used for:
• removing warts on the face or the genitals;
• skin conditions with signs of inflammation;
• dark moles, dark-colored, hairy or otherwise unusual looking skin conditions which resemble warts;
• warts on children under the age of four.

• For treating skin conditions with signs of inflammation;
• For removing dark moles, dark-colored, hairy or otherwise unusual looking skin conditions which resemble corns;
• On children under the age of four.
• If the nearby or affected skin is inflamed.
• If you are not certain that the skin condition you are treating is a corn or persistent callus.
• Consult a doctor if you are diabetic.
• Consult a doctor if you are pregnant or breast-feeding.

• Lower concentration of TCA gel: The Corn & Callus Pen contains TCA gel of less concentration compared to the Verruca & Wart Pen. The TCA gel induces a peeling of the skin. As this occurs, the thickened skin or corn will disappear and new healthy skin will form.
• Bigger pen containing 4ml of gel
• When used, apply only once a day
• In a pilot study, 85% of people assessed had complete removal of their corn or callus in just 1 week, clearly indicating that visible results are seen within the first treatment period of 4 days.

Hold the blue end of the foam applicator between the thumb and index finger and squeeze until a small opening appears. Slide the opening of the foam applicator onto the stick of the applicator holder until the stick is no longer visible.

Hold the aerosol can in an upright position, away from your body and from incandescent flames, heat, direct sunlight and any electrical sources. Place the applicator holder with the foam applicator in the opening on the top of the aerosol can so that the foam applicator is no longer visible. Holding the aerosol can with one hand at the bottom, firmly press down the applicator holder with the other hand for 3 seconds (count from 21 to 23). You will hear a hissing sound whilst pressing. Remove the applicator holder with the foam applicator from the valve. The foam applicator is saturated with cold liquid and condensation will form.  This condensation is harmless.

After saturation of the foam applicator, wait for 20 sec before topical application in order to further reduce application temperature and thus ensuring better efficacy.

After the 20 seconds waiting time, push the applicator holder with the foam applicator lightly on the wart (or verruca). For Warts: Apply for 20 seconds For Verrucas: Apply for 40 seconds Ensure constant contact with the area to be treated. The foam applicator should be applied to the area for the required treatment time.  A slight aching, stinging sensation will occur as a result of freezing.  After treating the wart or verruca, wait 2 minutes before using a tissue to remove the foam applicator from the holder. Discard the foam applicator after single use. Do not reuse the foam applicator or touch the tip of the foam applicator with bare hands to ensure that you don’t re-infect the skin with the HPV virus.

2 ADDITIONAL STEPS FOR VERRUCAS for optimal preparation and after treatment

See above. Same as for removal of warts

After applying for 40 seconds, you could experience some discomfort when pressure or friction occurs on the treated area. You may find it it helpful to protect the sensitive area with a comfort plaster which is widely available for purchase. Comfort pads are not included with Wartner.
