Alopecia
"I only used Rogaine for 2 days. At the end of my second day I developed a headache,  I took an Excedrin and my headache became a full blown migraine,  I broke out in a cold sweat  and got shaky. I then realized the Rogaine has a drug interaction with both the asprin and acetaminophen in the Excedrin.  I had to wait it out.  As a migraine sufferer I cannot use this drug for the side effects.  I am so disappointed. I purchased the  3 month supply."
