3. How to use Metrogel

Always use this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

  • Apply a thin layer of the gel to all the affected areas - be careful not to get it in your eyes.
  • Rub the gel in well.
  • Always replace the cap and wash your hands after use.
  • Your gel should be used in this way twice a day, (morning and evening), or as advised by your doctor.
  • Your doctor will decide how long you need to use Metrogel to keep your rosacea under control.

If you use more Metrogel than you should or accidentally swallow the gel

  • This product is for use on the skin only. Do not swallow it. If you accidentally do so, seek medical advice.
