Q. I'm starting to notice a couple of changes with my migraines and wonder if these are common. One is that I am getting mini-cluster headaches once or twice a day, 2 or 3 days before a big migraine attack, and the other is nausea with no migraine pain. I typically get the nausea after the migraine pain has begun, but is it possible it can switch?

Frovatriptan succinate is the latest of the medications collectively referred to as the "triptans" to be approved by the FDA for treatment of acute migraine headache attacks. The drug has been studied extensively in dose-ranging trials and double-blind placebo trials, controlled for efficacy and safety.
