You can try Excedrin Migraine or take 800 of Motrin with an Extra Strength Tylenol.
But taking Motrin every 5 hours is too soon depending on the dose you are using.
You would need to watch for worsening migraines with no relief at all. Also if you have sinus symptoms that could be adding to the headache.
We like to examine our patient if there is anything outside the norm of the regular migraine just to make sure that it is not a sinus infection or more than a migraine.
