An aqueous patch is provided which has excellent storage stability and provides excellent retention of butenafine hydrochloride blended therein onto the application sites such as skin and nails and is highly therapeutic. The butenafine hydrochloride-containing aqueous patch includes butenafine hydrochloride, glycol salicylate, and propylene glycol in a hydrogel paste. Specifically, the butenafine hydrochloride-containing aqueous patch is produced by dissolving butenafine hydrochloride in a mixed solution of glycol salicylate and propylene glycol and dispersing the resulting solution in a hydrogel is provided. In particular, in the butenafine hydrochloride-containing aqueous patch, glycol salicylate and propylene glycol are mixed in a ratio of 1:2 to 1:30.
