Cephalosporin powder can not be directly applied to the wound, it is recommended to standardize the treatment under the guidance of a doctor. Cephalosporin belongs to the antibiotic class of drugs, commonly used in tablets, capsules and granules, etc. It is mainly used for the treatment of diseases caused by bacterial infections, and can kill bacteria by inhibiting bacterial synthesis. If head spore powder is directly applied to a wound, the concentration of local antibiotics may be too large, which may cause bacteria to become resistant to the drug, thus failing to heal the wound. In the event of a wound, you can follow the doctor’s instructions to use iodophor disinfectant, hydrogen peroxide solution and other drugs to disinfect, and then use sterile gauze for bandaging treatment, which can effectively reduce the chance of wound infection. If a wound occurs, it is necessary to consult a doctor in a timely manner, and not to blindly use medication on their own, so as to avoid adverse consequences.
