Precautions

Caution: Do NOT use this device without first consulting a doctor or other health care professional.
Using this device poses minimal risk of injury. Even so, it is recommended to consider multiple treatment options. If symptoms worsen, make sure to contact a healthcare
professional.
The Flow device should only be used by people over 18 years of age who have been diagnosed with depression (Major Depressive Disorder).

• Pregnancy (or suspected pregnancy)
• Suicidal thoughts (thoughts about ending your life)
• Bipolar disorder (or having a history of hypomanic/ manic episodes)
• Epilepsy (or having a history of seizures)
• Heart disease (or suspected heart disease)
• A neurological or neuropsychiatric condition
• Having recently had a surgical procedure
• Having a defect in neurocranium and/or an implant inside the skull
•  Having an active, implanted medical device (e.g. cardiac pacemaker, spinal cord stimulator, vagal nerve stimulator, auricular stimulator, deep-brain stimulating electrodes,
  cochlear implant, implanted hearing aid or defibrillator) or other implanted metallic or electronic device.

Warnings

• Apply the headset ONLY on the head as directed and not on other body parts.
• Keep the headset dry and out of sunlight.
• Keep the headset out of the reach of children.
• Do not apply the headset over areas of skin that lack normal sensations.
• Do not apply the headset outdoors or close to water.
• Do not apply the headset while driving.
• Do not apply the headset during any activity creating a significant risk of injury.
• Do not apply the headset while intoxicated or incapacitated.
• Do not apply the headset in environments with strong magnetic fields.
• Do not apply the headset without the supplied Headset Pads.
• Do not apply the headset with dried-out Headset Pads (Pads are single use).
• Do not charge the headset with any other charger than the one supplied with the headset.
• Worsening of symptoms: If you experience a significant worsening of your symptoms while using this device, consult a physician before continuing the treatment.

Possible Adverse Reactions

• Some skin redness under the electrode or near the electrode sites is normal, due to increased local blood flow and will normally subside within approximately an hour of the end of use.
• DO NOT apply the device over open wounds, or broken or damaged skin. This might create further irritation and/or skin damage.
• Skin irritation might be experienced beneath the stimulation electrodes. In this case, electrodes should NOT be reapplied to the irritated skin.
• Discontinue treatment if the sensation of tingling, itching or burning under electrodes becomes severe (mild sensation of tingling, itching or burning is normal).
• Discontinue treatment if you experience a mild headache that does not pass within an hour after the end of a session.
• Discontinue treatment if you experience tinnitus (noise or ringing in the ears) during or after using the device.
• Discontinue treatment in case of any other adverse reaction from the device.

NOTE: Any serious incident that has occurred in relation to the device should be reported to Flow Neuroscience and the local competent authority.
Prerequisites

• A smartphone or other device running either Apple iOS 11+ or Android 5.0+.

The Treatment Program

• The Flow treatment programme consists of 15 sessions during the first 3 weeks, as shown in the table below.
• After this first treatment period, 1-2 sessions are recommended per week.
• The number of sessions you can do per week is restricted and you can only do 1 per day.
• Each session lasts 30 minutes, plus a few minutes of preparation time.
