CES Technology: FDA Regulations and Clinical Status
Cranial Electrotherapy Stimulation (CES) is a specialized technology used in healthcare, but its availability and application are strictly governed by regulatory bodies. In the United States, the Food and Drug Administration (FDA) oversees the classification and marketing of these devices to ensure patient safety and treatment efficacy.
Regulatory Classification in the United States
Currently, the FDA classifies CES technology as a Class III medical device. This is the most stringent classification, reserved for devices that require a high level of control to ensure safety and effectiveness. Because of this designation, CES devices cannot be purchased over-the-counter; they must be dispensed by or ordered by a licensed healthcare practitioner.
Eligible practitioners include physicians, psychiatrists, nurse practitioners, psychologists, physician assistants, or occupational therapists. Depending on specific state regulations, the practitioner must also hold an appropriate electrotherapy license. Consequently, a valid prescription is mandatory for obtaining a CES device in the U.S.

Evolution of FDA Oversight
The regulatory landscape for CES has shifted over the last decade. In June 2014, the FDA indicated a move toward easing some requirements. The agency determined that a combination of general controls and "special controls" could provide reasonable assurance of the safety and effectiveness of these devices.
As a result of this determination, the FDA withdrew proposed rules that would have required Premarket Approvals (PMAs)—the most rigorous type of device marketing application. The agency expressed plans to propose reclassifying CES devices from Class III to Class II, which typically involves less stringent oversight.
Current Market Availability
Despite the complex regulatory history, the FDA has cleared 11 specific CES devices for marketing within the United States.
Clinical Evidence and Depression Treatment
While CES devices are marketed for various uses, their efficacy in treating depression has come under scrutiny. In December 2019, the FDA announced that there was no valid evidence to support CES as a treatment for depression.
The FDA's conclusion was based on a review of four studies published between January 1, 2016, and November 1, 2019. The agency found that these studies failed to provide sufficient scientific evidence to prove that the subjects met the criteria for any recognized depressive disorder as defined by the DSM-5 (the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition). Consequently, the FDA has requested that new trials be conducted.

Frequently Asked Questions
Can I buy a CES device without a prescription in the US?
No. Because the FDA classifies CES technology as a Class III medical device, it requires a prescription from a licensed healthcare practitioner.
Who is authorized to prescribe CES technology?
Authorized practitioners include physicians, psychiatrists, nurse practitioners, psychologists, physician assistants, and occupational therapists, provided they meet state-specific electrotherapy licensing requirements.
How many CES devices are cleared by the FDA?
There are currently 11 CES devices cleared for marketing in the United States.
What is the FDA's current stance on CES for depression?
As of December 2019, the FDA concluded that there is no valid scientific evidence demonstrating that CES is an effective treatment for depressive disorders as defined by the DSM-5, and has requested new trials.
What happened to the PMA requirements for CES?
In June 2014, the FDA withdrew the proposed rule calling for Premarket Approvals (PMAs) after determining that general and special controls were sufficient for safety and effectiveness.
