Imiquimod

What is Imiquimod for?

Imiquimod works on the skin immune system and is indicated for the treatment of external genital and perianal warts in adults, actinic keratosis (solar keratosis) and cancerous skin conditions (superficial basal cell carcinoma).

This cream may also be used for other skin conditions as determined by your doctor.

How should I take or use Imiquimod?

• Apply imiquimod cream before going to sleep.
• Before applying the cream, wash your hands and the treatment area with mild soap and water and pat dry. Squeeze a small amount of cream onto your fingertip.

• Apply a thin layer of the cream to the treatment area and rub gently into the skin until the cream vanishes. Only use enough cream to cover the treatment area.

• After applying the cream, wash your hands with mild soap and water.

• Leave the cream on the affected area for 6 - 10 hours. Do not shower or bathe during this time.

• After 6 - 10 hours, wash the area where the cream was applied with mild soap and water.

• After several applications according to the course of treatment prescribed by your doctor, the lesions will shrink or dry up upon healing.

What should I do if I forget to take or use Imiquimod?

If you miss an application, apply it as soon as possible. However, if it is almost time for your next application, skip the missed application and go back to your regular usage schedule.

What precautions should I take when taking or using Imiquimod?

• Avoid contact with the eyes, lips and nostrils.
• Imiquimod cream administration is not recommended until the treatment area has healed from any previous drug or surgical treatment.

  • Sexual contact should be avoided while the cream is on the skin.
