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 if available from
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, mark your
calendar with a reminder.
Do not apply this medication to broken skin (such as
open wounds, infected areas, rash, burns). Also, 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.
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 imiquimod, tell your doctor or pharmacist
if you are allergic to it; or if you have any other allergies. This product
may contain inactive ingredients, which can cause allergic reactions or

Before using this medication, tell your doctor or

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. Do not apply this
medication onto sunburned skin. 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 if this drug passes into breast milk.
Consult your doctor before breastfeeding.
