Metrolotion is indicated for the topical treatment of inflammatory papules and pustules of rosacea (subtype 2, papulopustular rosacea). It may also be used off-label for other inflammatory skin conditions as directed by a healthcare provider.
Metronidazole has antimicrobial and anti-inflammatory properties. When applied topically, it helps reduce the inflammatory lesions associated with rosacea, though the exact mechanism in rosacea is not fully understood. It works by inhibiting the growth of certain bacteria and reducing inflammation in the skin.
Metrolotion is for external use only on the skin. Avoid contact with eyes and mucous membranes. Common side effects may include skin irritation, dryness, or redness at the application site. Use as directed by your healthcare provider, and inform them of any allergies or other medications you are taking.
