Summary

Imiquimod topical cream (Aldara, Beselna, Zyclara®) is an immune response modifier. It is used to treat certain types of skin growths including actinic keratoses (flat, scaly growths) and superficial basal cell carcinoma. It is available by prescription only. In horses imiquimod is primarily used to treat sarcoids and aural plaques.

Imiquimod stimulates the horse's own immune system to fight the tumor, through inflammation.

Imiquimod is applied topically to an appropriate skin growth. If a tumor is very large or thick, it may need to be debulked (reduced in size) first with surgery.
