rosacea
"I had used Metrogel for years, but it didn't seem to be making a difference any more, so I went to a derm & he prescribed Mirvaso.  I should have walked away when I saw the price!  The first couple of days I used it, my face and along my hairline itched.  Redness increased and acne appeared.  I stayed with it for two weeks; the flushing got worse and my face burned, along with my ears & neck.  Acne increased.  But the worst effect was the headaches.  I have migraines that I finally was able to manage with 2 prescriptions.  The derm didn't tell me a side effect of Mirvaso.  Did The FDA approved this?"
