The early double-blind studies of this device, as sent to the FDA for clearance, have excellent efficacy data with very few adverse events. Thus, it is used by many patients. The company has arranged a lower cost for the first month of treatment so a patient can see whether the device is effective.
There's also a device called Relivion®, which is worn like a tiara on the head to stimulate 4 nerves above the eyebrows that are part of the trigeminal system and 2 in the back of the head that affect the occipital nerves.
One of the earliest devices to launch is the gammaCore vagal nerve stimulator . It is handheld and controlled by the patient. It is placed on the front and side of the neck in the region of the vagal nerve. For acute care of migraine, the patient stimulates for 2 minutes and then waits several minutes before repeating 2 minutes of treatment. If you want to prescribe it for the prevention of migraine, a patient could do this sequence twice per day. It has been approved for acute care and prevention of migraine and, along with other medication for cluster headaches, it is easy to use and approved for almost any kind of headache. Unfortunately, it is extremely expensive for patients and is not covered well by insurance unless the patient is a veteran or goes to a Veterans Health Administration hospital for care.
There are a few other devices that also work for migraine. Most electrical stimulation devices are costly, but we do hope that insurance companies will begin to cover them soon. Most devices cause few adverse events, have few contraindications, and will be used more as they become more affordable.
Can you summarize migraine treatment for us in one paragraph?
No, but I will try. We have many acute care treatments for migraine that are effective. Some, such as the triptans, do constrict blood vessels, and certain patients should not be taking medications that affect blood vessels. Some medications cause certain side effects or take too long to work, and we have other options for those patients. If a patient has ≥4 headache days per month or fewer associated with a lot of disability, we need to consider prevention. We have older preventives such as beta blockers and epilepsy medications, which are less expensive and can work but usually have many side effects. Now we have 4 mAbs that bind to CGRP or its receptor, which work well for a month or more with few adverse events. We also have 2 oral gepants for prevention. When you add in several devices, I have so many options for my patients today that I am a lucky neurologist, and my patients are even luckier!
