Key takeaways
Metrogel (metronidazole) and Avar (sulfacetamide/sulfur) are both topical treatments used for skin conditions, but they have some key differences. Metrogel (metronidazole) is primarily used to treat rosacea, reducing redness and swelling, and is available in gel, lotion, and cream forms. It typically needs to be applied once a day and can take 3 to 4 weeks to show significant improvement. On the other hand, Avar (sulfacetamide/sulfur) is a combination medication used for acne, rosacea, and seborrheic dermatitis. It combines an antibiotic (sulfacetamide) and sulfur, which helps shed old skin. Avar can be applied once or twice daily and may take up to 12 weeks to see effects. While Metrogel is known for fewer side effects and can be used with makeup, Avar may have an offensive odor and can stain clothing. Additionally, Avar is not suitable for those with sulfa allergies and may not be appropriate during pregnancy or for children under 12.
