FL-100 is an FDA-approved, prescription-only at-home treatment for moderate to severe major depressive disorder in adults that uses transcranial direct current stimulation to deliver gentle electrical currents to mood-regulating regions of the brain.
It represents the first device of its kind authorized in the U.S., allowing clinicians to prescribe a non-drug brain stimulation therapy that can be used alone or alongside antidepressants or psychotherapy.
Patients typically follow a structured treatment course over several weeks, guided by the companion app for symptom tracking and therapy support.
