Medication Overuse Headache Successfully Treated by Three Types of Japanese Herbal Kampo Medicine.

Medication overuse headache (MOH) usually resolves after the overuse is stopped and starting prophylactic medications. However, it can be challenging to prescribe common prophylactic medications when patients have a history of side effects. As an alternative therapy, traditional Japanese herbal kampo medicine can be used. We herein report a case of a MOH woman with a history of side effects by such common prophylactic medications. A 50-year-old woman presented with a severe migraine attack. She had suffered from migraines for 10 years. She had taken loxoprofen and sumatriptan every day for over eight years. As prophylactic medications, lomerizine, valproic acid, and amitriptyline had been prescribed in the past, but they were discontinued due to side effects. Therefore, she could continue only propranolol as prophylactic medication. She had severe pulsatile headaches and nausea every day. We diagnosed triptan- and non-steroidal anti-inflammatory drug-overuse headache (the International Classification of Headache Disorders 3rd edition code 8.2.2 and 8.2.3.2) and chronic migraine (code 1.3). She was admitted and stopped loxoprofen and sumatriptan. We prescribed three types of Japanese herbal kampo medicines - kakkonto (TJ-1), goreisan (TJ-17), and goshuyuto (TJ-31). Her headache was relieved on day 5, and she was discharged on day 7. In the 40 days after discharge, she had only three times mild headaches with a numeric rating scale (NRS) of 2/10. She did not need any triptans nor anti-inflammatory drugs. We herein presented the MOH woman who was successfully treated using three types of kampo medicine. We should pay attention to their side effects, but kampo medicine may be useful for MOH treatment as acute and prophylactic medications for primary headaches.
