Children’s foot fungus can usually be treated with topical application of Dacronin, but children’s foot fungus needs to be treated selectively according to the specific state of foot fungus that occurs, as follows: 1. If children have foot fungus that is not too obvious and does not have obvious blisters or obvious erosions, it is perfectly acceptable to use Dacronin topical application, which is a fungicidal drug called miconazole nitrate, and is effective for children with fungal infections. For example, if there is obvious exudation or erosion, it is necessary to use dilute boric acid solution or Revnor solution to apply wet compresses in time to control local inflammation and exudation, and it is also necessary to take oral anti-inflammatory drugs, such as cefadroxil, to prevent infection. After controlling the inflammation then use antifungal drugs, such as dacrynic acid or paregoric pine, etc. These are possible.
