There is a triptan called Naratriptan, the brand
name is Amerge, and it tends to have much less adverse reactions than
Imitrex. It also doesn't work as well as Imitrex though so if the Imitrex works and doesn't cause you to have an adverse reaction, then I would stick with the Imitrex if I were you. But, I thought I would mention Naratriptan/Amerge just in case you needed a triptan option with a lower side-effect profile.
