Doxycycline
"Wow. I've had mild rosacea for years and had heard about this medication but was unable to take it because I was pregnant then nursing.  I saw results in just over a week. I don't even need to use the Metrogel anymore. I take it at night with a glass of water and have never had any side effects. I definitely recommend this. Luckily my copay is only $25 month. I was told to be careful with sun exposure while taking this but it's winter so I'm hoping this isn't a problem in summer."
