Accutane can be quite effective for rosacea, but it frequently takes longer to see a response as compared to Accutane for acne. It is relatively common for flares of either condition to occur while on Accutane (about 1/3 of patients) so to answer your question, although it is not "normal," we do see it. The flares generally last 4-6 weeks. It is likely that if you continue accutane at the current dose, you will see your rosacea improving within a few days to weeks. My suggestion would be to decrease the frequency of dosing to 3 times weekly or discontinue the medication all together until the flare subsides (approx 2 weeks), then re-start accutane 3 times a week (Mon,Wed,Fri). Injections of cortisone into the large rosacea bumps can also be very beneficial.
Good luck.
