Good Morning and welcome. I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
I believe that you are referring to Aldara creme used for Sarcoids in horses. This is Imiquimod 5% creme that is used by veterinarians for treatment of sarcoids and it appears that other uses are being researched.
You cannot purchase this yourself because it is sold only to veterinarians but this site will give you the information on how to purchase this product. LINK
I hope I got this right...please let e know if this is the worng creme.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please Reply so I can clarify for you
Sincerely, Dr. Loretta
