Medication overuse or rebound headaches can occur as the result of excessive intake of caffeine, opioid analgesics, and short-acting barbiturate drug, butalbital (contained in Fioricet, Esgic and similar drugs). These three substances not only worsen migraine headaches, they are also addictive. Two of my patients with medication overuse headaches were able to stop the offending drugs with the help of repetitive transcranial magnetic stimulation (rTMS).
One patient, a 51-year-old man, had his migraines under control with Botox and infusions of eptinezumab (Vyepti) until he sustained a head injury with a skull fracture. His migraines worsened and he became disabled. A variety of therapies failed to reduce his pain. His pain was partially relieved by 60 mg of oxycodone a day, although he still was unable to work. After six weekly sessions of rTMS he was able to start reducing his oxycodone intake and after eight, he completely stopped it. He was able to return to work with the help of injections of fremanezumab (Ajovy).
Another patient, a 50-year-old woman, had been taking butalbital with caffeine and acetaminophen (Fioricet) for 20 years. The number of pills increased over time and for the previous several years, she had been taking 10 to 12 tablets every day. She was also receiving Botox injections, infusions of eptinezumab, and taking rizatriptan (Maxalt), 10 mg three times a day as well as 60 mg of nortriptyline, 12 mg of tizanidine nightly and atogepant, 60 mg. She had tried a wide variety of other treatments but was unable to reduce her Fioricet intake. Despite her persistent migraines, she was able to take care of her family. After three weekly sessions of rTMS she reduced her Fioricet intake to 3-4 a day, by the third month she was taking one a day, and after 6 months she was completely off it. She was also able to stop atogepant and tizanidine and reduced her nortriptyline to 25 mg.
In addition to helping relieve pain and migraines, rTMS has shown promise in the treatment of addiction, particularly in addressing withdrawal symptoms, depression, and cravings. While the use of rTMS for addiction is still relatively recent and not yet FDA-approved, some studies have demonstrated positive outcomes. For instance, a double-blind study showed that individuals receiving rTMS therapy for cocaine addiction had a higher rate of abstinence compared to those who received standard treatment. rTMS for addiction is still considered experimental, and more research is needed to fully understand its long-term effects and optimal treatment parameters.
