- Measured outcome
- Low-dose (anti-inflammatory, sub-antimicrobial) oral doxycycline 40 mg once daily was significantly more effective than placebo at reducing inflammatory lesions in rosacea across two pivotal randomized, double-blind, placebo-controlled, multicenter trials (16 weeks). The 40 mg dose works as an anti-inflammatory.
- Certainty
- Moderate
- Who was measured
- Oral prescription treatment for inflammatory rosacea. A medicine.
