How is tetanus treated?

• A. Immediate antibiotic therapy is sufficient
• B. Supportive care and management of complications until toxin effects resolve
• C. Vaccination cures tetanus
• D. No treatment is available

Answer: (B)

Tetanus treatment centers on neutralizing any circulating toxin and keeping the patient safe while the toxin’s effects wear off. The toxin produced by the bacteria binds nerve tissue and blocks inhibitory signals, so symptoms can persist for weeks even after the bacteria are killed. If given early, antitoxin can neutralize circulating toxin, and wound cleaning with antibiotics helps stop new toxin from being produced, but these steps don’t reverse toxin already bound. The most important approach is robust supportive care—securing the airway, providing breathing support as needed, controlling muscle spasms, maintaining fluids and electrolytes, and monitoring for autonomic instability—until the toxin’s effects fade. Vaccination prevents future disease but does not cure an active tetanus infection, and there is indeed treatment available.
