Imiquimod
"I've been using this cream for 5 days now for anal hpv. Last night was the first night I skipped a treatment and I'll reapply it again tonight. I'm using it 5 x's a week. I have yet to experience the horrible reaction a lot of people complain about. And I've been using an entire packet of the cream.  It seems to be working different on everyone because everyone's immune system is different but I'm HAPPY to say that aldara appears to be working. In just 5 days I can already see the warts getting smaller. They are kinda red but they aren't painful just a little tender. No bleeding and no horrible side effects. Don't be afraid to use it. If u start getting bad side effects use less cream and space the days out more."
