What this medicine is used for
The name of your medicine is APO-Imiquimod. It contains the active ingredient imiquimod.
It is used to treat:
- Solar keratosis on the face and scalp.
Solar keratosis is thickened, scaly patches of skin caused by too much sun exposure. It is also known as actinic keratosis.
- Basal cell carcinoma (a type of skin cancer).
- External genital/perianal warts (condyloma acuminate). They appear on the surface of the penis or vulva (external female sexual organ) and around the anus.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
How it works
Imiquimod is an immune response modifier. It activates immune cells in the body. The immune cells then proceed to kill and remove the virus-infected or cancer cells.
Although the exact way that imiquimod works is unknown, it is believed to be due to its effects on the immune system.
There is no evidence that this medicine is addictive.
Use in children
This medicine should not be used in patients under the age of 18 years.

How to take this medicine
Follow carefully all directions given to you by your doctor. Their instructions may be different to the information in this leaflet.
How much to take
Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.

How to take it
Apply the cream as per your doctor's instructions.
Imiquimod cream is provided in single use sachets. A new sachet should be opened for each treatment, and cream from a previously opened sachet should not be used.
One sachet contains enough cream to cover a treatment area of 20 square centimetres (approximately 3 square inches).
- Before applying the cream, wash the treatment area with mild soap and water and allow the area to dry thoroughly.
- Apply a thin layer of cream onto the treatment area and rub it gently into the skin until it is no longer visible.
Sufficient cream should be applied to cover the treatment area.
For treatment of basal cell carcinoma, enough cream should be applied to cover the lesion and about 1cm of surrounding skin.
- The cream is to be applied to the affected area prior to normal sleeping hours and should be left on the skin for approximately 8 hours (6-10 hours). During the 6-10 hours treatment period, showering or bathing should be avoided. Following the treatment period, the cream should be removed by washing the treated area with mild soap and water.
Hand washing before and after cream application is recommended.
Contact with the eyes, lips, nostrils and hairline should be avoided.
The cream should not to be applied to the affected area more than once a day.
How long to take it for
Continue taking your medicine for as long as your doctor tells you.
Make sure you have enough to last over weekends and holidays.

If it is almost time to take your next dose, skip the missed dose and take your next dose at the usual time. Otherwise take it as soon as you remember and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for missed doses. This may increase the chance of you experiencing side effects.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.
If you take too much (overdose)

While you are taking this medicine
Things you must do
Tell your doctor that you are taking this medicine if:
- you are about to be started on any new medicine
- you are pregnant or are planning to become pregnant
- you are breast-feeding or are planning to breast-feed
- you are about to have any blood tests
- you are going to have surgery or an anaesthetic or are going into hospital.
Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects.
Go to your doctor regularly for a check-up.
Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.
Things you must not do
- Give this medicine to anyone else, even if their symptoms seem similar to yours
- Take your medicine to treat any other condition unless your doctor or pharmacist tells you to
- Stop taking your medicine, or change the dosage, without first checking with your doctor.
- Do not apply imiquimod cream to an area greater than 25 square centimetres.
- Do not use sunlamps or tanning beds, and avoid going into the sun as much as possible during treatment with imiquimod cream. Wear protective clothing if you go outside during daylight.
- Do not cover the treatment area with bandages or other dressings after you have applied imiquimod cream. Cotton gauze dressings are okay to use, if needed.
- If you are using imiquimod cream to treat genital warts, avoid sexual (genital, anal or oral) contact. If you decide to have sexual relations, apply imiquimod cream after, not before, sexual activity. If you have already applied the cream, it should be washed off before sexual activity.
Imiquimod cream may weaken condoms and diaphragms, therefore, the cream should be washed off before using a condom or diaphragm during sexual activity. Alternate forms of contraception should be considered.
Uncircumcised men with warts under the foreskin should pull the foreskin back each day and wash underneath it. If daily washing under the foreskin is not carried out, tightness of the foreskin may occur. Early signs of tightness include swelling and wearing away of the skin, or difficulty in pulling back the foreskin. If these symptoms occur, stop the treatment immediately and call your doctor.
Female patients should take special care if applying imiquimod cream at the opening of the vagina, because local skin reactions on the delicate moist surfaces can result in pain or swelling, and may cause difficulty in passing urine.
