If a patient has a red or swollen wound, the use of this drug is not recommended, especially for patients with open wounds or wounds that are not completely healed. It is recommended to consider using this medication only after the wound has completely healed because it is a topical medication, mainly used to treat fungal infections, and it can also lead to skin peeling and sometimes delayed wound healing and wound infection. If it is a fungal infection, sometimes topical antifungal medication is needed. At present, it is not recommended to use Footlight San for wounds.
