Imiquimod is used to treat actinic keratoses (AK) which
are precancerous growths on the skin. AK are caused by too much sun
exposure. Treating this condition can decrease the risk of complications
from them. It is also used to treat warts on the outside of the
genitals/anus. 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 as directed by your doctor, usually once a
day. The number of times you apply this medication depends on the specific
skin problem that is being treated. When treating actinic keratoses, apply
once a day for 2 weeks. You will then rest the treated skin for the next
two weeks by not applying any more imiquimod. After this rest period, you
will resume applying this medication once a day for another 2 weeks. When
treating warts, apply once a day until the warts clear or up to 8
weeks.
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, talk to your doctor right away.
If you are using the pump, prime the pump as directed
before using it for the first time. If you are using the packet, use a new
packet of cream for each use. Throw away any partly used packets of
medication.
Use this medication regularly in order to get the most
benefit from it. To help you remember, use it at the same time each day.
Before applying the medication, wash your hands and the area to be treated
with soap and water, and dry thoroughly. Apply as directed by your doctor
just before going to bed. Wash your hands with soap and water after each
application. Do not cover the treated area with bandages or other
waterproof coverings. Leave the cream on overnight, usually for about 8
hours. In the morning, wash the treated area with soap and water to remove
the cream. Do not bathe or wet the treated area before the prescribed
application time has passed. Do not use more imiquimod than prescribed or
leave it on longer than prescribed by your doctor. Doing so may cause more
severe skin reactions to occur.
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.
Headache, loss of appetite, dizziness, diarrhea, nausea,
or back pain may also occur. If any of these effects last or get worse,
tell your doctor or pharmacist promptly.
Remember that this medication has been prescribed

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
other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or
pharmacist your medical history, especially of:
This drug may make you dizzy. Alcohol or marijuana
(cannabis) can make you more dizzy. Do not drive, use machinery, or do
anything that needs alertness until you can do it safely. Limit alcoholic
beverages. Talk to your doctor if you are using marijuana
(cannabis).
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.
Before having surgery, tell your doctor or dentist about
all the products you use (including prescription drugs, nonprescription
drugs, and herbal products).
During pregnancy, this medication should be used only
when clearly needed. Discuss the risks and benefits with your
doctor.
