Key takeaways
Metrogel (metronidazole) and Finacea (azelaic acid) are both topical treatments for rosacea, but they have some key differences. Metrogel is a nitroimidazole antibiotic that helps reduce redness and swelling by lowering inflammation. It is typically applied once a day and can take 3 to 4 weeks to show significant improvement. On the other hand, Finacea is an antibacterial that works by stopping the growth of certain bacteria and also reduces inflammation. It is usually applied twice daily and may take up to 12 weeks to see results for rosacea. Metrogel is available in various forms like gel, lotion, and cream, while Finacea comes in gel, foam, and cream. Finacea can also lighten skin color, which might be a concern for people with darker skin tones. Both medications can cause skin irritation, but Finacea foam is noted to be flammable, requiring careful handling.
