rosacea
"I really wanted this medicine to work.  My doctor gave me a sample and I tried it for a week.  Then I got my prescription filled.  After two more weeks me face started turning red in the middle of the day.  I don't mean a little pink, I mean red, almost purple.  It would take several hours to subside.  My nose was affected worst.  In order to determine if the Mirvaso was the cause, I started using it on only one side of my face.  Sure enough, the side with the Mirvaso turned extremely red during the day.  I am going to stop using this medicine.  It was very expensive, but did not work for me."
