For papulopustular rosacea not fully responding to topical therapy, which systemic antibiotic is preferred?

• A. Doxycycline
• B. Moxifloxacin
• C. Amoxicillin
• D. Clindamycin

Answer: (A)

Papulopustular rosacea that doesn’t fully respond to topical therapy is often treated with a systemic antibiotic that has anti-inflammatory effects in addition to fighting bacteria. Doxycycline is preferred because, at low doses, it reduces inflammatory lesion counts through anti-inflammatory actions—such as decreasing neutrophil chemotaxis and downregulating inflammatory mediators—while offering a favorable safety profile and lower risk of antibiotic resistance compared with higher-dose regimens. This makes it effective for rosacea with fewer GI and other systemic side effects. Other systemic antibiotics don’t have the same balance of efficacy and tolerability for this condition. Moxifloxacin carries higher safety concerns and is less supported for rosacea, and amoxicillin or clindamycin have less robust evidence for this specific indication. The goal is to use a treatment with proven anti-inflammatory benefit that can safely control inflammatory lesions over time, which is why doxycycline is the choice.
