In 2020 in the United States, 15.3% of people over the age of 18 years reported experiencing a migraine headache or severe headache within the past 3 months.

This information comes from the Centers for Disease Control and Prevention (CDC).

This article looks at the Zok device for the treatment of migraine, some alternative options, when to contact a doctor, and some frequently asked questions.

Please note that the writer of this article has not tried this product. All information presented is purely research-based and correct at the time of publication.

According to the World Health Organization (WHO), migraine headaches often begin when a person reaches puberty. Migraine is most common in females due to female-specific hormones.

There are some drug treatments available for migraine, including:

  • sumatriptan
  • ergotamine drugs
  • ibuprofen
  • aspirin

Healthcare professionals may also recommend prevention methods such as exercise, relaxation techniques, and avoiding triggers through lifestyle changes.

Zok is a device that a person can insert into the ear.

It simulates the tympanic membrane through inner-ear pressure modulation, which the company claims reduces pressure and tension inside an individual’s head. This should, in turn, reduce the symptoms associated with migraine and headaches.

Brand and reputation

Dr. John D. Hatch created the device, and the team at Zok comprises healthcare practitioners and innovators.

Zok’s current Trustpilot page has no reviews or ratings.

Its Better Business Bureau (BBB) page has an average customer rating of 1 out of 5 stars. It has closed five complaints in the past 3 years, most of which mention refund difficulties and the device not being effective.

Reviews on the Zok website are all highly favorable and have 5 stars. However, it is worth noting that the company may have the ability to filter negative reviews from its page.

The device features a rubber bulb and an earbud. A person inserts this earbud into the ear while squeezing the bulb to deflate it. This creates an airtight seal between the Zok earbud and the ear.

A person holds this in place for 20–30 seconds before removing it from the ear. They then repeat this with the second ear. They can repeat the steps three to five times in each ear until pressure decreases.

Alternatively, a person can insert the earbud into the ear without deflating the bulb, creating an airtight seal. They can then partially deflate the bulb and further release five to 10 times in each ear.

While the device is in the ear, a person may experience a mild increase in pressure, but this should not cause added discomfort.

Individuals can use the Zok device multiple times throughout the day.

Zok is available to purchase online for around $40.

A person should take care when they insert the device. The airtight seal should be just past the entrance to the ear canal and in the same position as the person would place an audio earbud.

If the device causes any discomfort or pain, the individual should stop using Zok immediately.

The company does not note any side effects associated with the device.

A few examples of alternative drug-free migraine relief options include:

  • Nerivio: This is a smartphone-operated device that a person wears on the arm. They attach it when a migraine headache begins and set the intensity level. This device releases electric signals to inhibit incoming pain. For the best results, the manufacturer recommends wearing the device for 45 minutes. It has FDA approval.
  • Cefaly: A person wears this device on their forehead using a reusable self-adhesive. The device releases small electrical impulses to target the trigeminal nerve, which migraine often affects. Individuals can use this device when they initially experience a migraine episode or daily to prevent the risk of such episodes. This device also has FDA approval.
  • gammaCore: This device activates the vagus nerve in the neck using gentle electric stimulation. This nerve communicates with the brain and plays an important role in regulating pain. To use the device, a person applies gel to its stimulation surfaces, positions it in the correct area of the neck, and adjusts the intensity level accordingly. The device has FDA approval.

A person should contact a doctor if they have frequent or severe migraine headaches, as they may be able to prescribe medications to relieve or prevent them.

A person should seek urgent medical attention if they or someone they are with experiences any of the following symptoms:
