Over 2 months of treatment , SSRIs are no more efficacious than placebo in patients with migraine .
In patients with chronic TTH , SSRIs are less efficacious than tricyclic antidepressants .
In comparison with SSRIs , the burden of adverse events in patients receiving tricyclics was greater .
BACKGROUND Headache is a common medical problem .
In view of recent discoveries about the role of serotonin in pain mechanisms , selective serotonin re-uptake inhibitors ( SSRIs ) have been evaluated for the prevention of  migraine and tension-type headaches ( TTH ) .
OBJECTIVES To evaluate the efficacy and tolerability of SSRIs for preventing migraine and TTH .
Antidepressant treatment of chronic tension-type headache: a comparison between fluoxetine and desipramine.
Amitriptyline , which is a noradrenaline reuptake and 5-HT reuptake inhibitor , has an established role in the management of  chronic tension-type headaches .  In a single-blind study , patients with chronic tension-type headache were r and omized to either fluoxetine 20 mg ( a selective 5-HT reuptake inhibitor ) or desipramine 75 mg ( a selective noradrenaline reuptake inhibitor ) and followed for 12 weeks to compare the effectiveness of the two drugs in improving headache , and to assess whether pain control is related to changes in depression . Patients were evaluated at weekly intervals on an analog pain-rating scale and at 4-weekly intervals on the Montgomery and Asberg Depression Rating Scale ( MADRS ) , the MOS general health status question naire ( SF36 ) , the Hospital Anxiety and Depression Scale ( HADS ) , and a side effects checklist .  Eighteen patients were r and omized to take fluoxetine and 19 to take desipramine . Of the 25 patients who completed the trial , 12 were on  fluoxetine and 13 were on desipramine . There was no significant difference between the two groups at baseline nor in change of pain ; reduction in use of analgesic medication ; nor change in the HADS , MADRS , or SF36 scores at 12 weeks , but 72 % of patients who completed the study improved , and this improvement almost exactly mirrored the improvement on the MADRS . The results from this trial are compatible with the notion that the beneficial effect of antidepressants in  chronic tension-type headache  is indirect , mediated by an effect on depression , and not more , dependent on serotonin reuptake inhibition than noradrenaline reuptake inhibition
