About this medication

  • This medicine is a gel applied to the skin to treat the red bumps and pimples of mild to moderate rosacea, as well as the facial redness that comes with it.

Treats inflammatory lesions of mild-to-moderate rosacea.

How to use it

  • Wash and dry the affected skin before each application.
  • Apply a thin layer of the gel to the affected areas and gently rub it in.
  • Wash your hands after applying the gel.
  • Do not cover the treated skin with bandages or wraps.
  • Avoid getting the gel in your eyes, mouth, nose, or other sensitive areas. If this happens, rinse well with water.

If you miss a dose

  • If you forget an application, just apply it as soon as you remember and continue with your regular schedule.
  • Do not apply extra gel to make up for a missed application.

Apply a thin layer twice daily after cleansing. Reduce frequency and seek advice if irritation persists.

Pregnancy and breastfeeding

  • Only a small amount of this medicine is absorbed through the skin, so it is not expected to significantly affect breast milk, but use caution and tell your doctor if you are breastfeeding.

Discuss use during pregnancy or breastfeeding with your healthcare professional.

Missed doses, storage and accidental exposure

  • Store this medicine at room temperature.
  • Keep it out of the reach and sight of children.

Follow your own product’s missed-dose instructions. If you are unsure, ask the Care365 clinical team before taking an extra dose. Contraceptives, injections and modified-release medicines may need a specific plan.

Keep the original packaging and follow its storage, expiry and disposal instructions. Keep medicines away from children and pets. Ask about refrigeration, after-opening limits and safe sharps disposal when relevant.

For suspected overdose or accidental swallowing, contact poison control or urgent medical care promptly. Call emergency services for breathing difficulty, collapse or a seizure.

Key points to remember

  • This medicine is for use on the skin only — do not swallow it or put it in your eyes, mouth, or private areas.
  • Mild burning or stinging when you start treatment is common and usually settles down; tell the Care365 care team if it does not improve or gets worse.
  • Protect your skin from the sun and use sunscreen, since this medicine can make your skin more sensitive to sunburn.
  • Be patient — it can take a few weeks of regular use to see the full benefit.

These practical points come from the Pharmasist patient handout for the same product monograph cited by this guide.
