Tetanus injections include tetanus antitoxin and tetanus immune globulin, which are generally administered in the emergency or outpatient departments of public hospitals. Tetanus antitoxin requires a skin test before use, and patients allergic to it are prohibited from using it. Tetanus immune globulin does not require a skin test and can be injected directly. It is recommended to avoid alcohol before undergoing tetanus treatment, and it is generally suggested that the injection be administered within 24 hours after injury for better effectiveness. Overall, tetanus injections are usually performed in the outpatient or emergency departments of regular hospitals.
