"this is my emergency migraine medicine. i am on propranolol daily, and take rizatriptan when i have an actual migraine. once in a while, that doesn&#039;t help, and i have to go to my doctor for an emergency shot of toradol. i can have a migraine so bad that i can&#039;t open my eyes or speak, but this takes care of it in about an hour. the only side effect i experience is fairly severe pain at the injection site for about 5 days."
