This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.
This medication is used to treat certain types of growths on the skin. These are precancerous growths (actinic keratoses), a certain type of skin cancer (superficial basal cell carcinoma), and warts on the outside of the genitals/anus. Treating these conditions can decrease complications from them. Imiquimod belongs to a group of drugs called immune response modifiers. It is believed to work by helping to activate your immune system to fight these abnormal skin growths.
This product is not recommended for use on children under 12 years of age unless specifically directed by your doctor.
Read the Patient Information Leaflet provided by your pharmacist before you start using imiquimod and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Use this medication on the skin only. Apply this medication to the affected area(s) as directed by your doctor, usually just before you go to sleep for the night. If you are using the single-use packets, use a new packet for each dose. If you are using the pump, prime the pump as directed before using it for the first time.
Before applying, wash your hands and the area to be treated with mild soap and water. Dry the area well. Apply a thin layer of medication on the affected area(s) as directed and rub in. Wash your hands with soap and water after each application. Do not cover the treated area with bandages or waterproof coverings. However, you may cover the area with cotton gauze, or wear cotton underwear if treating the genital area. Leave the cream on overnight, usually for about 8 hours if treating actinic keratoses or basal cell carcinoma, or 6 to 10 hours for warts. Do not shower or bathe during this time. In the morning, wash the treated area with soap and water to remove the cream. Do not leave imiquimod cream on longer than prescribed.
The dosage and length of treatment is based on your medical condition and response to treatment. When treating actinic keratoses, this medication is usually applied twice a week for 16 weeks. When treating superficial basal cell carcinoma, this medication is usually applied 5 times a week for 6 weeks. When treating warts, this medication is usually applied 3 times a week for up to 16 weeks. Use this medication regularly to get the most benefit from it. To help you remember, it may help to mark your calendar.
Do not apply this medication in the eyes, nose, mouth, rectum, or vagina. If you get this medication in those areas, flush with plenty of water. If irritation occurs, contact your doctor right away.
Tell your doctor if your condition lasts or gets worse, or if new growths appear during treatment.
Treatment area reactions may include redness, swelling, itching, burning, pain/tenderness, thickening/hardening of the skin, peeling/flaking/scabbing/crusting, or leaking a clear fluid. Also, changes in skin color may occur and may not go away. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
If the skin reaction is severe (bleeding, formation of sores/blisters/ulcers), imiquimod may need to be temporarily stopped so that the skin can heal. Follow your doctor's directions.
Flu-like symptoms (such as fever, tiredness, muscle aches), runny/stuffy nose, cough, diarrhea, nausea, and back pain may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Before using this medication, tell your doctor or pharmacist your medical history, especially of:
This medication may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness.
Genital/anal warts are caused by a virus called human papillomavirus (HPV). Since imiquimod does not destroy the virus but only helps to eliminate the wart, new warts may form, even while you are being treated. You may also be able to infect any sexual partner who comes into contact with the areas of skin infected with HPV.
To reduce the risk of spreading HPV to others, always use effective barrier protections (such as latex or polyurethane condoms, dental dams) during all sexual activity. Consult your doctor or pharmacist for more details.
During treatment of genital/anal warts, avoid all sexual contact while the cream is on the skin. Condoms, dental dams, and diaphragms may be weakened by the cream, so they may not work as well to prevent pregnancy or spreading of HPV or HIV.
During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.
It is unknown whether this drug passes into breast milk. Consult your doctor before breast-feeding.
