The usual treatment process is to apply iodophor to the blister area for anti-inflammatory and antibacterial treatment, and at the same time apply a sterile syringe to extract the blister fluid, and then apply compound polymyxin B ointment and fusidic acid ointment on the surface for treatment after the blister dries up and the blister wall is relaxed. If the blisters are small and appear to not fuse with each other and the herpes fluid is small, it is not advisable to poke them at this time, and you should apply terbinafine hydrochloride gel and bifidazole ointment on the surface for antifungal treatment.
