high blood pressure
"I cannot take this medication.  I attempted to take it 2 different times and ended up with severe migraines.  I was foolish enough to take it a second time to make sure it was the medication.  Worst migraine of my life.  I had to take a 40mg Relpax and repeat the dosage one hour later to get some relief.  I was in so much pain, I paid $108 for 2 pills of Relpax that my insurance would not cover after trying Generic Maxalt.  Words cannot describe the head pain this medication caused."
