Medication-overuse headaches are a relevant medical and
social problem, for which specific treatments have not yet been
defined. In patients with chronic daily headache who take
analgesics every day, this headache is most likely to be caused
by drugs and will vanish with abstinence. Nonetheless, there is
anecdotal evidence that selective serotonin reuptake inhibitors
(SSRI) are effective in chronic daily headache, because of the
concomitant presence of psychiatric comorbidities (depression,
anxiety, or a combination of both). Six migraineurs were
admitted to the Neurology Clinic for medicationoveruse headache
and associated depression, anxiety and behavioural changes.
Treatment consisted in suppressing other drugs and by using an
SSRI, citalopram, at modest dosage (≤30 mg daily). Analgesic
withdrawal was performed in hospital and was not particularly
problematic. Over a 1-year follow-up, pain coping strategies
ameliorated and depression decreased; drug withdrawal was easy,
even from barbiturates, and pain control was good. Further
investigation into the possible use of citalopram or other SSRIs
in medication-overuse headache is waranted.
