Women need to lie on their stomachs to get tetanus in the buttocks, or it can be injected in the arm where the deltoid muscle attaches. Whether or not a woman needs to lie on her back for tetanus depends on the injection site decision. Tetanus generally refers to tetanus antitoxin, which can be injected subcutaneously in the deltoid muscle or intramuscularly in the gluteus maximus muscle. Tetanus antitoxin can also be used intravenously if you are already infected with tetanus. Generally tetanus is given in the buttocks, but it needs to be determined on a case-by-case basis. When tetanus is usually injected, a skin test is usually required before intramuscular injection to avoid bacterial infection and to facilitate wound healing and recovery. Pay attention to the skin test before tetanus injection. If the skin test is negative, there is usually no risk of allergy and you can inject it at once. If the skin test is positive, desensitization or tetanus immunoglobulin injection is needed. Specific medication should be injected according to your own situation and under the guidance of your medical professional.
