Welcome to the forum.
Your dermatologist has much more experience using imiquimod (Aldara) than I do. We don't use it as the main warts treatment in our STD clinic and I have personally treated very few patients with it. Please confirm my replies with your dermatologist.
1) The research studies with imiquimod applied it only to overt, visible warts. In theory, broader application might eradicate the more widespread HPV infection that usually accompanies warts, but to my knowledge this hasn't been studied. Please ask your dermatologist how he recommends applying it.
2) My understanding is that treatment should be withheld from overtly inflamed tissue, until it heals. But this too is something to ask the doc who prescribed it.
3) I can't say whether these or other treatments might prevent discoloration. My guess is they don't make much difference.
4) This too is for the dermatologist. I would think it reasonable to apply the medication to the areas that had visible warts for 2-3 treatments after the warts seem to be gone, but probably it isn't necessary to go beyond that.
6) Because of imiquimod's immunologic mechanism, it is often assumed (hoped might be a better word) that it might be associated with fewer recurrences than other wart treatments, and in its marketing efforts the manufacturer is happy to let people think so. But in fact there is absolutely no data to indicate it's true, and in my experience all wart treatments have more or less equal recurrence rates. On average, treatment with any particular method is about 70% effective; if treatment doesn't work or if warts recur, we switch to a different form of treatment. As for your lifestyle and nutrition, I really don't think it's going to make much difference one way or the other.
I hope these comments have helped. Best wishes-- HHH, MD
Also i just wanted to add that i am extreme greatful for the information that you have provided about HPV and GW. I was extremely depressed when i was first diagnosed but after really realizing what i was dealing with and how it is no different than warts appearing anywhere else on your body, i am much more at ease. I read many of your responses to other questions relating to HPV and they have really helped me put this virus into perspective. Your expertise and the wonderful way in which you deliver your advise and knowledge has been a god send to all of us lacking proper education about HPV.
Thanks for the kind words. Take care.
