, that is applied directly to the affected skin.
people with more severe cases, doctors often prescribe an oral (taken by mouth) antibiotic. Tetracycline, minocycline, erythromycin, and doxycycline are the most common antibiotics used to treat rosacea. Some people respond quickly, while others require long-term therapy.
