Excedrin Migraine contains aspirin, acetaminophen, and caffeine. My understanding is that caffeine boosts the effect of the pain relievers. Blowfish is a good substitute for Excedrin Migraine since it has similar, though not identical, ingredients.
I also like this Blowfish product because it doesn't have acetaminophen, some of my other meds already have plenty of that.View Thread
My neuro recommended using Blowfish in place of Bayer AM and Excedrin Migraine, both are off the market. It's a combination of aspirin and caffeine, in a fizzy tab like Alka Seltzer, and no acetaminophen.
They market it for hangovers, so I was hesitant at first (and the name is pretty funny!) but it really works well. I just take one tab early like you would with the other ones. I've only found Blowfish online but it's worth looking for.
I have had similar symptoms. Eventually they found that I also had mitral valve prolapse with the migraines. Exercising triggered both, a rapidly accelerating heart rate which then pushed into a migraine.
Perhaps you can ask your doctor for an EKG and an echocardiogram to see if you have that.
Now I get my exercise by walking and Pilates, I can't tolerate big aerobic workouts.
Hope this helps.
