No
The device description and performance studies focus on a cryosurgical system using a chemical mixture and mechanical components, with no mention of AI or ML.
Yes
The device is described as a "cryosurgical system for the over-the-counter removal of common warts and plantar warts," which directly indicates its use for a therapeutic purpose (treatment of warts).
No
The device is described as a cryosurgical system for the removal of common warts and plantar warts. Its intended use is to treat warts, not to diagnose them.
No
The device description explicitly lists physical components: a pressurized canister, a reusable activator, and disposable applicators. This indicates it is a hardware-based medical device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside of the body (in vitro).
- Device Function: The Dr. Scholl's Freeze Away Wart Remover works by applying a cryogen directly to the wart on the skin. It is a topical treatment that acts on the body, not by analyzing samples from the body.
- Intended Use: The intended use is for the "over-the-counter removal of common warts and plantar warts on the bottom of the foot." This is a direct treatment, not a diagnostic test.
The device description and performance studies also focus on the physical properties of the cryogen and applicator, and their effect on the wart, not on analyzing biological samples.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
a. Laboratory Testing
The average temperature of the Dr. Scholl's Freeze Away Wart Remover applicator surface after saturation is -42°C and is similar to that of the predicate devices.
b. Biocompatibility
The cryogen used is a mixture of dimethyl ether and propane, which is the same as the cryogen used in the primary predicate device (Wartner).
The standard biocompatibility studies recommended under ISO 10993 for a medical device with limited surface contact duration to breached/compromised skin were conducted on the applicator material and are included in this 510(k).
Applicator Effectiveness Duration
Dr. Scholl's Freeze Away Wart Remover maintains a temperature of -42°C at the applicator tip for approximately 170 seconds when tested using a temperature probe resting on a room temperature Teflon surface. A temperature of -57°C is measured if tested using a temperature probe held in mid-air. The method that employs a Teflon surface under the temperature probe is a more appropriate method for simulation of actual use conditions and was used for the substantial equivalence comparison.
The primary predicate device (Wartner) maintains a similar temperature (-36℃) for approximately 75 seconds, while the Histofreezer device maintains the same temperature as Freeze Away (-42°C) for approximately 230 seconds. All devices maintain the freezing temperature for a sufficient length of time to allow the product to be used according to the instructions for use.

-
- Description of Device:
Dr. Scholl's Freeze Away Wart Remover is a cryosurgical system for the over-thecounter removal of common warts and plantar warts on the bottom of the foot. The device consists of the following:
- Pressurized canister with a cryogen mixture of liquid dimethyl ether and propane a.
- b. Reusable activator that releases the cryogen into the applicators
- Disposable applicators C.
- d. Information booklet
-
- Intended Use Statement:
Dr. Scholl's Freeze Away Wart Remover is indicated for the over-the-counter removal of common warts and plantar warts on the bottom of the foot.
-
- Comparison of Technological Characteristics:
Dr. Scholl's Freeze Away Wart Remover is substantially equivalent to the Modification to Wartner Wart Remover System by Wartner Medical Products. The only significant difference between the two products is that the Freeze Away Wart Remover product is additionally indicated for the removal of plantar warts. For the over-the-counter plantar wart indication, we are claiming substantial equivalence to the Histofreezer Wart Removal System.
- Comparison of Technological Characteristics:
All 3 devices (Freeze Away, Wartner, Histofreezer) are portable cryosurgical systems comprised of a canister containing cryogen and an applicator that is saturated with cryogen and then applied to the wart to be treated.

K031697
a. Laboratory Testing
The average temperature of the Dr. Scholl's Freeze Away Wart Remover applicator surface after saturation is -42°C and is similar to that of the predicate devices (see below).
b. Biocompatibility
The cryogen used is a mixture of dimethyl ether and propane, which is the same as the cryogen used in the primary predicate device (Wartner).
The standard biocompatibility studies recommended under ISO 10993 for a medical device with limited surface contact duration to breached/compromised skin were conducted on the applicator material and are included in this 510(k).
c. Comparison to Predicate Devices:
Application
Dr. Scholl's Freeze Away Wart Remover includes an applicator that is saturated with cryogen and then applied to the wart to be treated.
The primary predicate device (Wartner) uses a similar applicator constructed of a different material.
Applicator Effectiveness Duration
Dr. Scholl's Freeze Away Wart Remover maintains a temperature of -42°C at the applicator tip for approximately 170 seconds when tested using a temperature probe resting on a room temperature Teflon surface. A temperature of -57°C [similar to that listed in 510(k)s K011708 and K924114] is measured if tested using a temperature probe held in mid-air. The method that employs a Teflon surface under the temperature probe is a more appropriate method for simulation of actual use conditions and was used for the substantial equivalence comparison.
The primary predicate device (Wartner) maintains a similar temperature (-36℃) for approximately 75 seconds, while the Histofreezer device maintains the same temperature as Freeze Away (-42°C) for approximately 230 seconds. All devices maintain the freezing temperature for a sufficient length of time to allow the product to be used according to the instructions for use.
Crvogen
Dr. Scholl's Freeze Away Wart Remover uses a cryogen composed of dimethyl ether and propane.
The primary predicate device (Wartner) uses the same cryogen.
2
Safety / Ease of Use
Dr. Scholl's Freeze Away Wart Remover includes a safety feature whereby the cryogen will be released into the applicator only after the applicator is attached to the pressurized can and pressed onto the activator. The applicator on the Freeze Away product also contains a luer lock which allows the applicator to be twisted onto the can, preventing accidental detachment during activation or treatment.
The primary predicate device (Wartner) utilizes the first safety feature listed above but does not contain the second safety feature.
Indications for Use
Dr. Scholl's Freeze Away Wart Remover is indicated for the over-the-counter removal of common warts and plantar warts.
The primary predicate device (Wartner) is indicated for the over-the-counter removal of common warts, while a second predicate device (Histofreezer) is indicated for the over-the-counter removal of common warts and plantar warts.
Labeling
The labeling of Dr. Scholl's Freeze Away Wart Remover has been developed to ensure the consumer has adequate directions for safe use. Freeze Away labeling has also been developed to provide adequate information for the consumer to make a self diagnosis and to ensure that they contact their doctor if in any doubt, if stinging or aching persists after treatment, or if the wart does not improve after four treatments.
The safety and warning statements for the OTC predicate device (Modification to Wartner Wart Removal System) are essentially similar.
7. Conclusion
Based on the information presented above, it is concluded that the proposed Dr. Scholl's Freeze Away Wart Remover is safe and effective for its intended use when used in accordance with label directions and is substantially equivalent to the predicate devices.
