Without tetanus shots, there is a risk of contracting tetanus and developing muscle spasms, which in severe cases can endanger the patient’s life. After contracting tetanus, in the early stages of the disease, the patient will experience weakness, headache, dizziness, weakness in chewing, and tightness in the facial muscles. If the disease progresses further, it can lead to muscle spasms, and the patient will experience clenching of the teeth, corns, and stiffness in the neck. If the respiratory muscles are affected, it may lead to respiratory failure, which can endanger the patient’s life.

Generally choose tetanus antitoxin, in the injection of this drug before the need to do skin tests, can prevent anaphylactic shock.
