Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Plantar warts can be treated with Duofilm solution (Salicylic acid). Before applying Duofilm, clean the foot with soap and lukewarm water. Using pumice gently rub the wart. Then apply the solution. Take care not to apply the solution on normal skin. Allow some time for the solution to dry. Repeat this daily once at bedtime. If it does not show any response in 2 weeks, do consult your dermatologist. Hope I have answered your query. Let me know if I can assist you further.
