Antibiotics Used to Treat Acne Rosacea

Doxycycline, minocycline, and tetracycline are antibiotics used to treat a wide variety of bacterial infections including acne.

The systemic treatment of erythrosis (a chronic state of capillary dilation in
rosacea) is based on the association of H. pylori with rosacea, although researchers are still debating this association. Studies have shown the eradication of H. pylori using systemic treatments such as doxycycline and minocycline. Additionally, researchers are currently investigating a low-dose doxycycline. This treatment may provide greater safety than existing oral antibiotics.

Researchers are also examining the role of tetracycline in treating rosacea. Data pooled from three studies in The Netherlands of oral tetracycline versus placebo involving 152 patients showed that, according to physicians, tetracycline was effective, so there is some evidence that oral tetracycline is effective.
