Hi all. New here. Have been diagnosed rosacea since last June/July time. This will be my 9th month on the same antibiotic (lymecyline) . It did seem to help at first however the last 3/4 months my skin has got really bad. Lots of papsules and a rashy red texture , not to mention it itches like crazy ! Could I have developed a resistance to the antibiotic ? If so is it worth asking my gp to switch me to a different one ?
