A wearable device claiming to block the pain of opioid withdrawal has been cleared by the Food and Drug Administration under an expedited review process for medical devices. However, patient safety advocates note that the device has limited evidence for its effectiveness.
The NSS-2 Bridge is a device that attaches to the ear and transmits small electrical pulses through four cranial nerves. It’s marketed by Indiana-based Innovative Health Solutions, and was cleared to treat chronic and acute pain in 2014. IHS can now market the device as one that reduces symptoms of opioid withdrawal including nausea, anxiety, and aches.
