Question: how to get rid of a headache that just won't go away?
Answer: Most commonly, rescue treatments are strong NSAIDS like toradol or difenolac, but can also be diphenhydramine, anti-emetics (like Zofran, Compazine, or Phenergan), or even opioids. A rescue treatment should be a medicine that you can administer at home when your abortives fail.
