Tetanus Immunoglobulin Dosage for Active Tetanus Treatment

Dosing Guidelines for Active Tetanus

• The Centers for Disease Control and Prevention recommends a standard therapeutic dose of 3,000-6,000 units of tetanus immunoglobulin for active tetanus cases, which is significantly higher than the 250 units used for prophylaxis in wound management 1, 2, 3
• When administering tetanus immunoglobulin, it must be given at a different site than any tetanus toxoid-containing vaccine using separate syringes 1

Treatment Protocol for Active Tetanus

• Tetanus immunoglobulin works by neutralizing circulating tetanus toxin but cannot neutralize toxin already bound to nerve endings 4

Clinical Pearls

• The Centers for Disease Control and Prevention suggests that tetanus immunoglobulin should be administered as soon as possible after diagnosis 3
• Despite proper treatment, tetanus still carries significant mortality risk, emphasizing the importance of prevention through proper immunization 4
