IMIQUIMOD 2.5% - TOPICAL
(im-I-kwi-mod)
COMMON BRAND NAME(S): Zyclara
USES: 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. Imiquimod belongs to a group of drugs called immune response modifiers. It is believed to work by helping your immune system to fight these abnormal skin growths.
HOW TO USE: 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 once a day for 2 weeks as directed by your doctor. 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.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.

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 increases the risk of severe skin reactions.Tell your doctor if your condition lasts or gets worse or if new growths appear during treatment.
