I am prescribed triptans for my chronic daily migraines.
My Headache Specialist is adamant that I stick to these rules.
a) You don't use them when you've got aura (this relates to my hemiplegic migraines)
b) You only use them 2 days per week (that means either the Almogran or the Imigran, i.e. 5 days without either)
c) You don't use Imigran and Almogran on the same day.
Like all medications have side-effects triptans are no exception. I am in no means trying to put you off as they can provide some much needed relief but it is good just to be aware.
