A Better Solution for Every Care Provider
Discover Spark Wearable Neurostimulation solutions to treat opioid withdrawal.

Flexible, Drug-Free Therapy, Better Patient Outcomes
Whether transitioning patients to MAT/MOUD or eliminating opioids from daily life, managing opioid withdrawal is a pivotal first step. It’s a critical moment - a chance to stabilize patients in withdrawal or risk losing them to an AMA discharge. Studies show approximately 10% of patients leave against medical advice in the first three days of treatment – many due to unmanaged withdrawal.
