Patients should use their device for 20 minutes a day until symptoms are resolved. When depression, anxiety and/or insomnia symptoms are completely resolved (full remission), patients may discontinue use of the device. If symptoms are significantly reduced but not in complete remission, patients may continue with daily use. Many patients continue using their device after their symptoms go into remission in order to derive the focus and concentration benefits that the device provides.

Medical devices that require a purchase authorization or prescription from a licensed healthcare provider are not allowed to be sold on Amazon. As a result, Fisher Wallace sells the wellness version of the Fisher Wallace Stimulator®, called Circadia®, on Amazon. Circadia® clones the technology of the Fisher Wallace Stimulator® but is intended for sleep and stress management.

If we have an authorization on file, the device will ship within 5 - 10 business days. You may track your package via the link that is emailed to you after purchasing the device.

Patients use the Fisher Wallace Stimulator® at home for 20 minutes, once or twice a day on "Level 2." Patients with insomnia use the device within two hours of bedtime. Consistent daily use in the first 30 days is recommended.

If mood and sleep symptoms are reduced but do not go into remission within the first 30 days, patients may continue using the device on a daily basis. The device has been on the market since 1990 without reports of negative effects resulting from long term use.

If mood and sleep symptoms go into remission (no symptoms), patients may use the device three to four times per week -- or as needed -- to maintain their results. There are no withdrawal effects associated with decreasing or stopping use of the device.

The device may be safely used in conjunction with antidepressants and/or other medications. Patients should not reduce or cease taking medication without first speaking with their doctor.

The answer is yes and the reason is that the Fisher Wallace Stimulator® employs a completely different method of action than drug therapy. Instead of inhibiting neurons from absorbing serotonin, as antidepressant medication does, the Fisher Wallace Stimulator® activates brain regions, such as the basal ganglia and dorsolateral prefrontal cortex, that are responsible for mood, sleep and cognition.

Whereas pharmaceutical drugs must be FDA-Approved to enter the market, medical devices must be FDA-Cleared. The Fisher Wallace Stimulator® is FDA-Cleared to treat depression, anxiety and insomnia.

The Fisher Wallace Stimulator® can be used by all patients except those with implanted medical devices, such as an implanted nerve stimulator or pacemaker. The device is contraindicated for use on the body in patients who have demand or sensing type cardiac pacemakers. The stimulator's electrical impulses may interfere with the functioning of such implanted devices.

Additional precautions:

  • This device should not be used around the Carotid sinus.
  • Patients with known or suspected heart disease should not be stimulated.
  • Patients who react poorly to the idea of electrical stimulation of any kind should not use this device.
  • Patients whose skin is irritated around either electrode site should discontinue use of this device.
  • This device must be used only for the purpose for which a physician or healthcare professional has prescribed or authorized.
  • This device must only be used by the person for whom the prescription or authorization has been written.

Neurostimulation devices such as the Fisher Wallace Stimulator® are cleared by the FDA for the treatment of insomnia, anxiety and depression.

Transcranial Direct Current Stimulation (tDCS) is not cleared by the FDA for the treatment of depression, anxiety or insomnia. tDCS was FDA approved in 2004 for Iontophoresis, which is a noninvasive method to deliver medicine or other chemicals through the skin with external patches and a small electrical charge. Transcranial Direct Current Stimulation (tDCS) is not typically an at-home treatment modality, and as a result, can be very expensive because it often requires office visits and doctor supervision during treatment sessions. Insurance companies will not reimburse patients for purchasing or using tDCS for “off label” uses such as the treatment of depression.

The Fisher Wallace Stimulator® and ECT both deliver alternating current to the brain for therapeutic effect, but at vastly different doses. The Fisher Wallace Stimulator® provides very gentle stimulation therapy designed for daily home use without doctor supervision - it does not cause a seizure or serious side effects. ECT, while often effective, is performed in a hospital while the patient is under anesthesia and is designed to induce a seizure. ECT often causes memory loss. Following are more differences:

1. ECT delivers 800 – 1000+ mA of electricity, which causes a seizure.

The Fisher Wallace Stimulator® delivers 1 – 4 mA of electricity, which does not cause a seizure. In fact, the Fisher Wallace Stimulator® is recommended for treating substance abuse patients who are prone to seizures.

2. ECT is administered when a patient is under anesthesia.

The Fisher Wallace Stimulator® delivers such a mild current that patients typically wear it while reading a book, on the computer or watching TV. The stimulation from our device is rarely perceived and is not uncomfortable.

3. ECT delivers a large amount of electricity in a single dose.

The Fisher Wallace Stimulator® delivers a gentle amount of electricity on a daily basis.

4. ECT typically costs $30,000 and, while effective initially, its effects wear off.

The Fisher Wallace Stimulator® costs $799 and the effects do not wear off when the device is used on a regular basis.

5. ECT is indicated to treat severe depression.

The Fisher Wallace Stimulator® can be used to treat temporary or situational depression as well as chronic, severe depression. Our device has also been cleared by the FDA for the treatment of anxiety and insomnia.

Ideally, you should use the device twice a day for 20 minutes until your symptoms go into remission. If you no longer have symptoms, you can stop using the device and then renew treatment if the symptoms return. The device has been on the market for decades without any reports of long-term negative effects. Many patients have used the device for years.

When used cranially to treat insomnia, depression and anxiety, less than 1% of patients report a mild headache upon using the device.

Although not a side effect, improper use of the device may result in minor electrode irritation - this can occur if the sponges are not thoroughly wet before use. Please watch the instructional video and read the instruction manual thoroughly before using the device. People with very sensitive skin may find that the sponge electrodes, even when wet, cause a slight irritation to the skin - but this is very rare.

The Fisher Wallace Stimulator® works by stimulating the brain to produce neurochemicals such as serotonin, while modulating the default mode network and entraining alpha waves. The device treats insomnia but is not a sedative - instead, the device modulates the brain to produce a restful state that accelerates sleep onset and restores longer periods of sleep.
