Overview
Treatment of diphtheria consists of the administration of the diphtheria antitoxin (if the disease is identified early), administration of the right antibiotic therapy, as well as the identification of individuals in close contact with the patient, so that they may be provided with the appropriate prophylaxis.[1][2][3][4][5][6]
Medical Therapy
Treatment of diphtheria consists of the administration of the diphtheria antitoxin (if the disease is identified early), administration of the right antibiotic therapy, as well as the identification of individuals in close contact with the patient, so that they may be provided with the appropriate prophylaxis.[1][2][3][4][5][6]
- 1. Antitoxin
- 1.1 Pharyngeal disease <48 hrs
- Preferred regimen: 20,000-40,000 U IV/IM
- 1.2 Nasopharyngeal
- Preferred regimen: 40-60,000 U IV/IM
- 1.3 Extensive disease, or > 72 hrs
- Preferred regimen: 80-120,000 U IV/IM
- Note: IV administration may be suitable for severe disease
- 2. Antibiotics
- Preferred regimen: Erythromycin 40 mg/kg/day (Maximum, 2 gm/day) PO/IV for 14 days
- Alternative regimen: Procaine penicillin G 600,000 U/day IM qd for 14 days
- Note: Procaine penicillin G 300,000 U/day for those who weigh 10 kg or less
- 3. Preventive antibiotic use
- Note: For close contacts, especially household contacts, an age-appropriate diphtheria booster should be given
- Preferred regimen: Benzathine penicillin G
- younger than 6 years old: 600,000 U IM
- 6 years old and older: 1,200,000 U IM
- Alternative regimen: Erythromycin
- Adult: 1 g/day PO 7-10 days
- Pediatric: 40 mg/kg/day PO 7-10 days
- Note (1): If surveillance of contacts cannot be maintained, they should be given benzathine penicillin G
- Note (2): Maintain close surveillance and begin antitoxin at the earliest signs of illness
