FDA decisions on vagus nerve stimulation include implants approved for epilepsy, depression, stroke rehabilitation and, in 2025, rheumatoid arthritis, plus gammaCore, a neck device cleared for headache pain on prescription. Home neckbands sold for stress and sleep sit outside those decisions: they are marketed as general wellness products rather than treatments, and that is how to read their claims.

Search for a vagus nerve stimulator and two phrases keep appearing: "FDA approved" and "FDA cleared". They sound interchangeable. They are separate decisions, and neither is the label the neckband's maker uses. Knowing which is which takes about five minutes and saves a lot of confusion at checkout.
What is the difference between FDA approved and FDA cleared?
Approved means the device went through premarket approval, which the FDA calls "the most stringent type of device marketing application". Approval rests on the FDA finding enough valid scientific evidence that the device is safe and effective for its intended use. Implanted stimulators take this route. In the FDA's database these records carry a "P" number.
Cleared means the FDA found the device "substantially equivalent" to one already on the market, through a 510(k) notice. Its records carry a "K" number. Clearance is still a real FDA decision, tied to a specific indication.
Both are always for something: a named condition, a named patient group, often a named setting. "FDA approved" with nothing after it tells you very little. The useful question is always "approved or cleared for what?"
Which vagus nerve stimulators has the FDA approved or cleared?
The five decisions below are the ones most readers ask about. They are not a complete list of every FDA record in this field. Each line links to the FDA's own record in the sources.
| FDA decision | Device and route | What it is for |
|---|---|---|
| 16 July 1997, approval P970003 | VNS Therapy System, surgically implanted | Epilepsy |
| 15 July 2005, supplement S050 to the same approval | VNS Therapy System, surgically implanted | Depression |
| 27 August 2021, approval P210007 | Vivistim System, surgically implanted, used during rehabilitation therapy | Reducing upper-limb motor deficits and improving motor function in chronic ischemic stroke patients with moderate to severe arm impairment |
| 23 January 2018, clearance K173442 | gammaCore-S, held against the side of the neck, Class II, prescription use only | Acute treatment of pain associated with episodic cluster headache and migraine in adults |
| 30 July 2025, approval P240039 | SetPoint System, surgically implanted | Adults with moderately to severely active rheumatoid arthritis who have had an inadequate response, loss of response or intolerance to one or more biologic or targeted synthetic disease-modifying drugs |
Sources: FDA premarket approval and 510(k) databases, records P970003, P970003/S050, P210007, K173442 and P240039, read on 15 and 16 October 2026.
Two patterns stand out. Every approval on that list is for an implant placed by a surgeon. The non-invasive device on it, gammaCore-S, was cleared for headache pain in adults, on prescription. Its 510(k) summary describes each stimulation as lasting two minutes on the side of the neck.
Is Pulsetto FDA approved?
No, and the brand does not claim it is. Its store describes the neckband as "a general wellness product" that "is not intended to diagnose, treat, cure, or prevent any disease or medical condition", and its product page adds that it "is not a medical device".
That places it in a separate lane from gammaCore. It is sold without a prescription, and the brand describes its purpose as helping customers manage stress, support better sleep and promote overall wellness. For a buyer, three things follow:
- You can order it directly, without a doctor's prescription.
- It is meant as a daily self-regulation tool, not as treatment for any condition you have been diagnosed with.
- You judge it the way you judge any wellness gear: by whether you keep the routine, inside the 30-day money-back window the brand offers.
Our full review of the Fit, written in the same wellness terms, covers what the short neck sessions involve, the realistic timeline and who should skip it.
How should you read stress and sleep claims on a home device?
The FDA has a guidance document for exactly this. "General Wellness: Policy for Low Risk Devices", issued on 6 January 2026 and replacing the 2019 version, lists the kinds of claims it treats as general wellness. They include "relaxation or stress management" and "sleep management".
The same document gives examples of claims that fall outside that category. One of them reads: "A claim that a product helps treat an anxiety disorder".
That gives you a working vocabulary for any product page:
- Wellness language: helps you unwind, supports a calmer evening, part of a sleep routine, stress management.
- Medical language: treats anxiety, cures insomnia, replaces medication, reverses a disease.
When a home device uses the second kind of language, look for an FDA record that matches it. Without one, the claim goes beyond what the general wellness category covers.
What should you check before buying any home stimulator?
- What does the brand say the device is?Look for a plain statement: medical device with an FDA record you can find, or general wellness product. Either can be legitimate. The problem is a vague mix of both.
- Do the claims match that label?Wellness devices should talk about stress, relaxation and sleep routines, not about treating a diagnosed condition.
- Who does the brand say should not use it?A clear list, starting with pacemakers and other active implants, is a sign the company has thought about safety. Our checklist of who should not use a vagus nerve stimulator gathers the main ones.
- What happens if it does not suit you?Check the money-back window, the return conditions and any ongoing costs before you order.
A device that passes all four is honest about what it is. From there the decision is personal: whether a short daily session fits your life.
Frequently asked questions
Is the Pulsetto neckband FDA approved?
No, and it is not marketed as FDA approved or cleared. The brand describes it as a general wellness product that is not intended to diagnose, treat, cure or prevent any disease, and its product page says it is not a medical device. It is sold for relaxation, stress and sleep routines.
What is the difference between FDA approved and FDA cleared?
Approval comes through premarket approval, which the FDA describes as its most stringent type of device marketing application, and is the route the implanted vagus nerve stimulators took. Clearance comes through a 510(k) notice showing a device is substantially equivalent to one already marketed, which is how gammaCore-S was cleared in 2018. Both apply only to the specific use named in the record.
Is there an FDA-approved vagus nerve stimulator for anxiety?
None of the FDA decisions listed on this page is for anxiety: they cover epilepsy, depression, stroke rehabilitation, headache pain and rheumatoid arthritis. The FDA's general wellness guidance gives "A claim that a product helps treat an anxiety disorder" as an example of a claim outside general wellness. If anxiety is affecting your life, talk to a doctor about care.
Can I buy gammaCore without a prescription?
The 2018 clearance, K173442, lists gammaCore-S as prescription use only, for the acute treatment of pain associated with episodic cluster headache and migraine in adults. Check with your doctor for its current status and whether it suits you.

About the author
Alex Moreno writes the health-gadget guides at Lume-Trixa. His interest started at home: his grandmother spent years with intense, burning nerve pain that her doctors struggled to explain in simple terms. That sent him into reading about nerve conduction, inflammation, supplementation and health technology, and into tracking sleep and body data with wearables to look for triggers. He chooses and buys the products he writes about himself, the way any shopper would, then checks them against the published research. He is not a doctor, and his guides are general information, not medical advice.
