My daughter had warts on both of her hands, 2 to 3 around each nail bed, one big one on her knee, and another one on the bottom side of her arm close to her elbow, a total of about 25 to 30 warts altogether. Since she had so many on her hands, I took her to her pediatrician (old school pediatrician, I think he is in his 60s) because she wanted to get them removed. Because he is old school and because he knows his stuff, he suggested putting my daughter on old school Tagamet, generic is called cimetadine. It is an old ulcer medication that is not prescribed much anymore because of all the newer products that have been put out. She took this medication for 3 months and EVERY SINGLE one of her warts including the 2 bigger ones are gone COMPLETELY. They have never came back and she has been off the medication for 5 years now. She took it when she was 10. She never had to have a single one removed and it took care of ALL OF THEM.
He said the medication had been shown to work with certain types of warts, depending on what kind and he thought it was worth a try instead of trying to freeze off all of them (very painful). Within a month they were starting to disappear, within 3 months they were gone.
