Rizatriptan 10 mg 1 at onset and another after 2 hours if needed. Max 2 a day max 8 treatments a month so i usually use my rescue but I’ve had times when I had a lot of migraines and I was nervous that I would out use my max monthly useage. I’ve talked to my dr about changing my base usage method but most months this all works so the rare times that side use age of the excedrine is a winning method so far.
