Imiquimod - Side Effects, Precautions, and Contraindications

What side effects can Imiquimod cause?

Common side effects include:

  • Skin reddening, swelling and flakiness
    • These reactions are normal as they are signs of your immune system fighting the abnormal cells. Even if these symptoms are not present, the medication may still be working.
  • Formation of crust during healing
  • Itching
  • Burning sensation
  • Stinging
  • Lighter skin colour on the warts or around the warts

Should the skin reactions become too uncomfortable, remove the cream by washing with mild soap and water. Take a short break of 3 to 4 days before continuing it again. If any side effects persist or are severe, please consult your doctor.

For genital or perianal warts
