First-line medication for skin and soft tissue infections

Generally, there is no specific first-line drug for skin and soft tissue infections. Treatment can be selected based on the severity of infection and individual health status, including the use of topical medications such as mupirocin ointment and fusidic acid cream, or oral antibiotics such as cefaclor capsules, amoxicillin capsules, and azithromycin capsules. All medications should be used under the guidance of a qualified physician. Detailed explanations are as follows:

1. Mupirocin Ointment: This medication has strong antibacterial activity against Gram-positive cocci, especially Staphylococcus aureus and Staphylococcus epidermidis, and can be applied directly to the infected area.

2. Fusidic Acid Cream: Primarily used for skin infections caused by Gram-positive bacteria, such as impetigo, furuncles, and carbuncles. It is usually applied about three times daily and can effectively inhibit bacterial growth and proliferation.

3. Cefaclor Capsules: A cephalosporin-class antibiotic effective against various Gram-positive bacteria and some Gram-negative bacteria. The dosage is typically determined by the physician according to the condition.

4. Amoxicillin Capsules: A penicillin-class antibiotic commonly used to treat skin and soft tissue infections caused by susceptible bacteria. It is usually taken daily, with dosage determined by a physician's instructions.

5. Azithromycin Capsules: A macrolide-class antibiotic with antibacterial activity against Gram-positive bacteria and some atypical pathogens. The dosage and administration should be determined based on the patient's condition and physician's instructions.

It is recommended not to scratch or rub the infected area to avoid skin breakdown and bleeding, which may lead to further infection spread. Additionally, try to avoid contact between the infected area and irritating substances, such as alcohol-based disinfectants and chemical detergents.
