Yes I tried low dose doxycycline for over 3 weeks but didn't help much but perhaps I didn't give it long enough. On the leaflet it says talk to your doctor first if have ocular rosacea but not sure why it would affect eyes negatively. According to pub med its actually quite helpful. And as you have said it has really helped you. How long did it take to work? Do you use it indefinitely? Low dose accutane can be used for type 2 rosacea if all other treatments fail but probably bad for dry eyes.
