imiquimod topical Uses
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.How to use imiquimod topical

Wash your hands with soap and water after each application. Do not cover the treated area with bandages or other waterproof coverings. Covering the area with cotton gauze, or cotton underwear if treating the genital area, is permitted.

Also, changes in skin color may occur and may not go away. If any of these effects persist or worsen, 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.

imiquimod topical Precautions
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: recent/unhealed surgery on the skin area to be treated, immune system problems (including HIV infection), a certain complication of bone marrow or some organ transplants (chronic graft-versus-host disease), autoimmune diseases (such as rheumatoid arthritis, scleroderma, lupus).
This medication may make you more sensitive to the sun. Avoid prolonged sun exposure, tanning booths, and sunlamps. Use a sunscreen and wear protective clothing when outdoors.
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, and therefore 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.
