FDA Zaps Tongue Nerve Stimulators into Moderate Regulation Category
Published Date: 12/19/2025
Rule
Summary
The FDA is officially classifying the electrical tongue nerve stimulator, a device that helps people with movement problems, as a Class II device with special safety rules. This change makes it easier and faster for patients to get this innovative treatment by reducing some regulatory hurdles. The new classification is effective December 19, 2025, and could speed up device availability without extra costs for users.
Analyzed Economic Effects
4 provisions identified: 2 benefits, 2 costs, 0 mixed.
Class II ruling speeds patient access
The FDA classified the electrical tongue nerve stimulator as a Class II device with special controls, which the agency says will enhance patients' access and reduce regulatory burdens. The final order is effective December 19, 2025, and FDA states this classification can make it easier and faster for patients to get this treatment.
Creates predicate for future devices
Because FDA classified this device via the De Novo process, the electrical tongue nerve stimulator can serve as a predicate device. Future device sponsors can use the less-burdensome 510(k) process instead of a De Novo request or premarket approval, lowering regulatory hurdles for companies making similar devices.
Manufacturers must meet special controls
To be classified as Class II, manufacturers must meet special controls including biocompatibility testing for patient-contacting components; electromagnetic, battery, electrical, mechanical, and thermal safety testing; non-clinical performance testing of stimulation parameters; software verification/validation and cybersecurity assessment; and specific labeling (technical summary, instructions, cleaning, storage, charging, disposal).
Device is prescription-only
The FDA states the electrical tongue nerve stimulator is a prescription device. That means the device is available only with a prescription and is exempt from layperson 'adequate directions for use' requirements under specified statutory provisions.
