Imiquimod (skin cream)

im-mi-kwi-mod

What does it do?

Imiquimod is used to treat some skin conditions, such as genital warts and certain types of skin cancer.

Before you start

  • Tell your doctor if you have eczema or psoriasis, HIV, or if you have had a transplant.
  • Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you use it?

Wash the affected area of skin and allow to dry. Wash and dry your hands, then using a fingertip rub the cream into the treatment area until it disappears. Wash your hands again when you are finished.

Apply imiquimod at bedtime, and leave on for 6 to 10 hours as directed before washing off. Imiquimod is usually applied for 5 days in a week for skin cancers and 3 days in a week for genital warts and other skin conditions.

If you are using imiquimod for skin cancer, apply enough cream to cover the affected area and 1 cm of skin around it.
For all other conditions, apply enough cream to cover the affected area.

Avoid having sex soon after applying the cream to your genitals because it may irritate your partner’s skin. Try to apply it after sex rather than before.

What if you forget a dose?

If it is nearly time for your next dose, skip the missed dose and apply your next dose at the usual time. Otherwise, apply the missed dose as soon as you remember. Do not apply the cream more than once a day.

Can you take other medicines?

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
