Impetigo is treated primarily with antibiotic creams or ointments applied directly to the affected skin, such as mupirocin or hydrogen peroxide cream. For more severe cases or if the infection has spread widely, oral antibiotics may be prescribed. It is important to complete the full course of treatment as directed by a healthcare provider. Additional care measures include washing the sores gently with soap and water, keeping the affected area clean and covered with a nonstick bandage to prevent spreading, and practicing good hand hygiene. Avoid touching or scratching the sores to prevent the spread or worsening of the infection. Children or individuals with impetigo should stay away from school, daycare, or work until no longer contagious — typically 48 hours after starting antibiotic treatment or when sores have dried and crusted over. Preventive steps also involve washing clothes, towels, and bedding frequently at high temperatures, avoiding sharing personal items, and cutting fingernails short to reduce scratching. In summary, treatment involves:

• Topical antibiotic creams (e.g., mupirocin or hydrogen peroxide cream)
• Oral antibiotics for extensive or severe cases
• Good hygiene and wound care practices
• Avoidance of contact with others until non-contagious

Finishing the full treatment course is essential to clear the infection and prevent recurrence or resistance.
