Multi-Pack CryoBuds BUDP come in small, medium, and large sizes.
What lesions can I treat with a canister of Verruca Freeze?
The most recent cryosurgery textbooks state that -50°C is adequate to treat most benign skin lesions. Verruca-Freeze delivers freezing temperatures of -70°C, exceeding the minimum recommended freezing temperatures. The FDA has cleared Verruca-Freeze® for removal of 21 types of lesions including: warts, plantar warts, seborrheic and actinic keratoses, achrochordon (skin tags), molluscum contagiosum, age spots, dermatofibroma, small keloids, granuloma annulare, porokeratosis plantaris, angiomas, lentigo maligna, keratoacanthoma, lentigo discreta, chondrodermatitis, epithelial nevus, leukoplakia and pyogenic granuloma.
How many lesions can I treat with a canister of Verruca Freeze?
A 95ml canister contains approximately 35 freezes, the 162ml canister contains approximately 65 freezes and the 236ml canister contains approximately 100 freezes. The number of lesions you can treat with a canister will depend on how large and deep the lesions are since some lesions may require a second freeze in the same office visit. For example, difficult plantar warts may require 2 or 3 freezes at the same visit while venereal warts require a very light single freeze. The number of treatments also depends on how much pressure you use to squeeze the trigger. The number of freezes per canister was determined by using the 5mm cone.
Some physicians increase the number of lesions they treat successfully by combining chemical treatment with cryosurgery. They use salicylic acid after cryo to treat difficult plantar warts and podophyllum after cryo to treat small, invisible venereal warts.
What are the methods of application for Verruca Freeze?
Verruca-Freeze has two methods of application: transparent limiting cones, available in five sizes (3mm, 5mm, 7mm, 9mm, 12mm) and CryoBuds™ available in sizes small, medium and large. CryoBuds™ are convenient in hard-to-reach or bony areas of the body. CryoBuds™ are disposable. They can be used more than once on the same patient, but are not interchangeable between patients.
The limiting cones are reusable and should be soaked in bactericidal solution for sterilization. Cones can be autoclaved on the lowest setting if desired.
What is the recommended freeze time for Verruca Freeze?
Spray time is approximately 3 to 6 seconds. When using the transparent limiting cones, accumulate approximately 1/8th inch (3mm) of cryogen into the cone. When using the CryoBud™, saturate the bud to its first drip point.
Freeze time varies depending on the size, type and depth of the lesion. Freeze time is approximately 20-30 seconds. Allow a thaw time of approximately 40 seconds, no more than 55 seconds. We recommend two freeze-thaw cycles on lesions greater than 5mm and plantar warts.
By watching the training video, reading the instruction manual, and practicing on the practice media sent with each kit, you will soon learn how much of the cryogen to spray. Freeze and thaw times are important in order to achieve success in effectively treating lesions with Verruca-Freeze®
If you feel you have sprayed too much Verruca-Freeze®, let the cryogen spill to the floor, then remove the limiting cone, and place your hand on the lesion to stop the freeze cycle. Always protect the eyes and ears when performing cryosurgery.
What is the shelf life of Verruca-Freeze and how do I store it?
A canister of Verruca-Freeze has a minimum of a 5 year shelf life. Just store it in a room where the temperature does not exceed 100°F and the canister is kept out of direct sunlight.
Why should I use Verruca-Freeze instead of Nitrous oxide?
Nitrous oxide can also be used for cryosurgery and is usually applied with a cryoprobe. To use nitrous oxide a physician must have a gas cylinder, a regulator, a pressure gauge, and a cryogun with assorted tips. While the gas does not evaporate like liquid nitrogen, the cost of the basic tank, without the probes can be close to $2,000 with the probes costing well over $100 each. When the tank is empty a refill can run from $50 to $178 plus delivery charges. Because the temperature is warmer than liquid nitrogen, nitrous oxide is not suitable for treating malignant cells. Nitrous oxide is a known teratogen. In addition, because of studies done on health care professionals showing adverse health consequences, OSHA requires that all nitrous oxide systems be vented directly outside. This is not practical in many office situations.
