This device is also listed with the Therapeutic Goods Administration (TGA) in Australia (ARTG No. 509725 & 510555). It has also received the Food and Drug Administration (FDA) Breakthrough Device Designation for at-home depression treatment in the United States.
The technology Flow uses is transcranial direct current stimulation (tDCS). tDCS has been used in clinical settings for decades, and its safety and performance has been evaluated in hundreds of clinical trials.

It is important to always use Flow in accordance with the Flow Neuroscience user manual.

Flow - Transcranial Direct Current stimulator (tDCS) is only to be used under the supervision of an appropriately qualified health practitioner.

Who can use Flow?

If you're 18 or older and have been told by a doctor you have depression (mild, moderate or severe), Flow could work for you. Because of the way Flow works, it doesn't interfere with medicines you may be taking and is generally safe to use if you have other medical conditions including diabetes, asthma, hypertension, are neurodivergent, or if you suffer with other mental health conditions in addition to depression.

If an of the following applies to you, talk with your doctor or qualified health practitioner before deciding to use the headset:

You are thinking of changing something about your current treatment, for example changing your antidepressant dosage
You are unsure about your diagnosis
You are pregnant, think you might be, or become pregnant while using Flow
You currently have thoughts about suicide or harming yourself
You have been told there is a problem with your skull or if you have metal parts in the skull, cochlear implants or brain pacemakers such as those used for Parkinson's disease. It is fine to use the device if you have dentures
You have epilepsy or have had seizures
You have a chronic skin condition affecting your forehead, such as psoriasis
You have bipolar disorder

What are the common side effects?

Over 20,000 people have used Flow and less than 5% have reported side effects¹.

The most common side effects experienced are:

Skin reactions (redness, irritation, itching, stinging, minor burns)
Headache
Tinnitus
Worsened symptoms of depression including increased anxiety
Tiredness, fatigue and general malaise including sleep disruption

These side effects typically resolve within a few hours to no more than a few days, and many users tend to adapt to the treatment over time, resulting in a reduction or disappearance of side effects with continued use.

Can Flow treat other conditions?

Flow is certified solely as a treatment for depression. Although it is deemed safe to use Flow for depression alongside other conditions such as obsessive-compulsive disorder (OCD), attention-deficit/hyperactivity disorder (ADHD), or post-traumatic stress disorder (PTSD), we strongly advise against using Flow for any purpose other than depression treatment.
