wash affected area and dry thoroughly
if necessary, cut medicated patch to fit callus
apply adhesive side down of medicated patch onto callus
cover medicated patch with pad
after 48 hours, remove medicated patch
repeat procedure every 48 hours as needed for up to 14 days (until callus is removed)
may soak callus in warm water for 5 minutes to assist in removal
continued wearing of pad (without patch) will help prevent recurrence of calluses
