EpiWatch is available in the U.S. Seizure detection, monitoring, and caregiver alerting require a prescription from a U.S. clinician.

CLINICALLY VALIDATED SEIZURE DETECTION EpiWatch is powered by an FDA-cleared seizure detection algorithm that detected 98% of tonic-clonic seizures in clinical trials with a false alarm rate of .08 per 24 hour period.
