Migraine treatment: Moderate to severe (Formulary: CNS)

Guidelines

Reserve triptans for patients resistant to simple analgesics and antiemetic therapy; if the headache always progresses to a moderate to severe attack despite patients taking acute therapy when symptoms are still mild, then consider triptans.

Use during the established headache phase and not during the aura phase of an attack.

Continue triptan treatment for 3 months and only discontinue at that point if ineffective. If one triptan is ineffective then consider trial of another.

Advise patients that triptans should be taken on no more than 2 days per week due to the risk of developing medication overuse headache.
