I am a 21 year female, I had got genital warts which were treated by application of podophyllotoxin application, and then they were gone one month back. Now, they appear to be regrowing at the same spots. So I applied podophyllotoxin today again, and my derma suggested 2 dpt injections on my vagina at the places where I got the warts, the next week. Is it safe? Is it correct and useful? Will I get permanently rid of warts after this dpt injection? Or is there any other more effective treatment of procedure that can be done? Please help asap.
