Should any treatments be avoided?

  • During pregnancy, chemotherapeutic agents, interferon, and retinoids should be avoided, and careful consideration should be given to use of acids and cantharidin. Liquid nitrogen and laser are safe for use during pregnancy.
  • Bleomycin should be avoided around fingernails, as permanent nail dystrophy, Raynaud’s phenomenon, and sclerotic changes in the distal finger have been reported.
  • X-irradiation is not indicated for treatment of warts. Increased invasiveness of lesions following radiation has been reported.
