Dermatologist's Take
Topical metronidazole is a well-studied, first-line prescription for the bumps and redness of rosacea. It is gentle and easy to use, but it works slowly and does not cure the condition — symptoms often return if you stop.

How it works
Doctors do not fully know how metronidazole works for rosacea. It seems to calm inflammation (skin swelling and irritation) in the skin. It also has mild antibacterial and antiparasitic effects. Together these actions reduce the red bumps and pus-filled spots of rosacea.
What it treats
How it's typically used
Metronidazole is usually applied to the whole affected area, not just single spots. The 0.75% forms are often used twice a day. The 1% forms are often used once a day. Wash and dry the skin first, then rub in a thin layer. Many people use it long-term to keep rosacea under control. This is educational only — follow your own prescriber's directions.
Common side effects
- Mild stinging or burning where you apply it
- Dryness, redness, or peeling
- Itching or mild irritation
- A metallic taste (uncommon with skin use)
Serious side effects
- Strong allergic reaction (rash, swelling of the face or lips, trouble breathing) — rare
- Severe skin irritation or worsening redness
Call your doctor if you have a bad reaction or if your skin gets much worse.
Who shouldn't take it
Do not use it if you have had an allergic reaction to metronidazole or similar drugs. Use care around the eyes. Tell your doctor about any past skin reactions.
