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.

Most patients experience benefit in the first week of daily 20-minute treatments. The device should be used every day for 2 - 4 weeks before making a decision to keep it or return it.

It’s recommended that you use the Stimulator for 20 minutes a day until symptoms go away. When depression, anxiety and/or insomnia symptoms are completely resolved, you may stop using the device. If you feel that your symptoms are significantly reduced but did not go away completely, you may continue to use the device daily. Many people continue using their device after their symptoms go away because they find they can focus and concentrate better, additional benefits that the Stimulator provides.

How it Works

If the green indicator light AND at least one yellow light are illuminated, the device is delivering stimulation. If there is no yellow light illuminated, the sponges may not be sufficiently moist, or the batteries may need to be replaced.

Many patients do not feel the stimulation at all, while some may feel a mild tingling at the sponge contact sites.

The Fisher Wallace Stimulator® works by gently stimulating your brain to produce certain naturally occurring chemicals that improve mood. One of these chemicals is serotonin, known as the body’s mood regulator. The Stimulator also promotes alpha waves, which have a calming effect on the body. Additionally, the device helps to lower cortisol, your body’s stress hormone. The Stimulator treats insomnia but is not a sedative - instead, the device helps your brain produce a restful state that accelerates sleep onset and enables longer periods of sleep.

Ideally, you should use the device twice a day for 20 minutes until your symptoms go away. If you no longer have symptoms, you can stop using the device and then renew treatment if symptoms return.

Is the Fisher Wallace Stimulator® different from other stimulation devices?

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.

Who should NOT use the device?

The Fisher Wallace Stimulator® can be used by everyone EXCEPT for those people implanted medical devices, such as an implanted nerve stimulator or pacemaker. The device should not be used if you 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.
  • If you have known or suspected heart disease, you should not use the Stimulator
  • If you have reacted poorly to the idea of electrical stimulation of any kind, you should not use this device.
  • Discontinue use if your skin becomes irritated around either electrode site
  • 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.

How to Assemble

You should use the Fisher Wallace Stimulator® at home for 20 minutes, once or twice a day on "Level 2." If you have insomnia, use the device within two hours before bedtime. If you are not suffering from insomnia, you can use the device whenever it’s most convenient for you. Consistent daily use in the first 30 days is recommended.

If mood and sleep symptoms are reduced but do not get resolved within the first 30 days, continue using the device on a daily basis. It 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), use the device three to four times per week -- or as needed -- to maintain your results. There are no withdrawal effects associated with decreasing or stopping use of the device.

The device may be safely used with antidepressants and/or other medications. Do not reduce or stop taking your medication without first speaking to your doctor.

Are there any side effects? Is the device FDA regulated?

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 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.

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.
