Wartner Cryotherapy is based on the liquid nitrogen method of cryotherapy, which is used by doctors. Clinical studies have proved that Wartner Cryotherapy is as effective as liquid nitrogen.

A clinical study to compare efficacy, tolerance and safety of 2 types of cryotherapy (liquid nitrogen (LN) and dimethylether/propane (DMEP) was performed by family physicians for warts on 124 patients (174 warts). Design of the study: randomized, multi-centered, controlled clinical trial with single blind assessment. Conclusions: The results show that both cryogenic agents were >90% effective. Liquid Nitrogen has a temperature of -196ºC, whilst DMEP is -57ºC and therefore much less likely to cause deep tissue damage.

Dermatologists confirm Wartner Cryotherapy’s effectiveness: “the efficacy of Wartner Cryotherapy freezing fluid is as effective as commonly used liquid nitrogen (= doctor’s method). In case of thick callosity we remove the callosity by scraping in a gentle way and apply Wartner Cryotherapy freezing liquid effectively” Dr I H Boersma – Dermatologist – Albert Schweizer Hospital – Zwijndrecht, The Netherlands.

“The effectiveness of Wartner Cryotherapy is comparable to that of the classic technique (Liquid Nitrogen = doctor’s method) in every respect, and the freezing effect it has is similar to that obtained by Liquid Nitrogen, perhaps a little slower (20″ application instead of 3″ application), which I think is safer and less painful” Dr J M Gray – Dermatologist – Paris, France

Wartner 2^nd Generation reaches a temperature on skin of -50° which is the coldest therapeutic temperature reached on the market as a cryotherapy.

Based on clinical research, Wartner clearly outperforms competition in relation to therpautic temperature and saturation of the applicator.

If you follow all the directions in the instruction leaflet correctly, using Wartner Cryotherapy will not result in scarring. Skin discoloration may occasionally occur, but will disappear over time.

No, if you have several common warts or verrucas in the same area, treat only one at a time. Treat each remaining wart or verruca separately with a 2-week interval between treatments.

No. Wartner Cryotherapy should be applied with precision, but it’s not difficult. The information leaflet explains exactly how you should apply Wartner Cryotherapy.

You press the valve down firmly for three seconds.

No. After pressing the foam applicator into the valve for 3 seconds, 20 seconds need to be waited before application on skin. This waiting period allows the gas on the foam applicator to reduce even further in temperature, resulting in the most effective therapeutic temperature for a fast and convenient removal of the wart/verruca.

Warts: (max.) 20 sec.
Verrucas: (max.) 40 sec.

Each foam applicator may be used once only and should then be discarded to avoid spreading the virus.

Only one per hand or foot may be treated by Wartner Cryotherapy at a time.

Wartner Cryotherapy may be used up to 3 times per wart or verruca. You should leave a 2-week interval between treatments.

For old or persistent warts or verrucas, two or three applications maybe required. To help with treatment, remove the top layer of skin with a pumice stone or emery board; this will expose the core. Treat each wart or verruca with a 2-week interval between treatments. Consult your doctor if there is no improvement after three treatments.

A successfully treated wart or verruca usually means that it has been removed permanently. The body’s immune system will normally purge any remaining traces.

• 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 Cryotherapy should not be used on children under the age of four.

There are a number of possible side-effects:

• 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 Cryotherapy 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 Cryotherapy very carefully and accurately. If you’re not careful, scars and nerve damage may occur.

• 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.

Always consult a doctor if the stinging sensation does not disappear or if other complications occur through using Wartner Cryotherapy.

Wartner Cryotherapy may be used by most adults. You can also use Wartner Cryotherapy to remove warts and verrucas on children over the age of four, but the treatment must be carried out by an adult.

Yes, Wartner Cryotherapy is suitable for children over the age of four.

We do not recommend the use of Wartner Cryotherapy to treat children under the age of four.

No. Do not use Wartner Cryotherapy if you are pregnant or breastfeeding.

It takes approximately 10-14 days for the wart or verruca to disappear.

If the wart or verruca doesn’t disappear after 14 days, you can treat it again. You can treat each wart or verruca with Wartner Cryotherapy a maximum of three times, with a 2-week interval between each treatment.

If the wart or verruca doesn’t disappear after three treatments, you should go to your doctor.

Wartner Cryotherapy has a number of important advantages. It saves time and is easy to use. You no longer have to wait at the doctor’s surgery. The liquid nitrogen that your doctor uses has a much lower temperature than Wartner Cryotherapy. Because of this Wartner Cryotherapy is less painful but just as effective.

Wartner Cryotherapy is manufactured by Omega Teknika – Farnham Drive, Finglas, Dublin 11, Ireland, and is distributed by Omega Pharma by its local affiliates.

You can buy Wartner Cryotherapy at your local pharmacy or supermarket.

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 flame, 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 a better efficacy of Wartner.

After the 20 seconds waiting time, push the applicator holder with the foam applicator lightly on the wart. For Warts: use the applicator for 20 seconds For Verrucas: use the applicator 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, 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 wart virus.
