Before undergoing tetanus treatment, it is advised not to drink alcohol. This is because there are two types of tetanus injections: the tetanus toxoid, which requires a skin test, and the tetanus immunoglobulin, which does not require a skin test. Drinking alcohol causes the capillaries to dilate, leading to skin redness, which can affect the results of the skin test. A positive result in the skin test, indicated by skin redness, means that tetanus toxoid cannot be administered, and instead, the more expensive tetanus immunoglobulin must be used. Moreover, for deeper wounds such as open injuries and fractures, tetanus treatment is essential. Tetanus infection can have severe consequences if not treated properly.

Which part of the body is the tetanus shot administered?

Tetanus injections are given as intramuscular injections in the upper arm or the buttock. Tetanus vaccines include tetanus antitoxin, which requires a skin test. Patients with a positive skin test must either undergo desensitization therapy or avoid using it, and can switch to tetanus immunoglobulin, which doesn't require a skin test but is more expensive than tetanus antitoxin. The purpose of the tetanus shot is to prevent infection by Clostridium tetani, an anaerobic bacterium. It is particularly important for patients with deep wounds or heavily contaminated wounds; or wounds contaminated with rust or soil to receive tetanus treatment to prevent Clostridium tetani from colonizing the body through wound mucosa and producing neurotoxins that affect breathing.

Do you get a fever during the early stages of tetanus?

Tetanus symptoms can potentially begin with a fever during the early stage, generally occurring between six and ten days after injury, meaning symptoms can appear within 24 hours or several weeks post-injury. The shorter the incubation period, the more severe the symptoms and the higher the risk. Some patients may experience fatigue, headache, dizziness, restlessness, and possibly fever. Subsequently, typical symptoms of tetanus occur, primarily characterized by intense muscle contractions starting with the facial muscles. This includes difficulties in opening the mouth and lockjaw, among others. Thus, prevention is crucial for tetanus. When there is a local tissue injury, it is essential to promptly disinfect with hydrogen peroxide or iodine, followed by cleaning and suturing the wound and timely tetanus vaccination to prevent the disease.

How long is a tetanus shot effective?

It is definitely better to get a tetanus shot as soon as possible, ideally within 24 hours after injury, as the chance of prevention is much higher compared to other times. Once an injury occurs, it is essential to go to a formal hospital for wound treatment, and then use disinfectant products, typically hydrogen peroxide or iodophor, to assist in disinfection. Generally, for open wounds, stitching may be necessary, but such wounds should generally not be bandaged because bandaging can lead to anaerobic bacterial infection. Since the incubation period for Clostridium tetani, the bacterium that causes tetanus, is five to seven days, an infection could potentially develop during this time. Therefore, it is advisable to get vaccinated against tetanus infection within a week. If this timeframe is exceeded, it might impact the effectiveness of the preventative measure, thus rendering it significantly less meaningful.

How long does a tetanus shot last?

Regarding how long a tetanus shot lasts, it depends on which type has been administered. Generally, there are two types of tetanus injections: tetanus immunoglobulin and tetanus antitoxin. Typically, doctors perform a skin test before administering the tetanus antitoxin; if the patient has a positive skin test and cannot tolerate desensitization treatment, tetanus immunoglobulin can be administered instead. These two medications have different metabolic times and their preventive effects vary. The metabolic time for tetanus antitoxin is generally one week, whereas for tetanus immunoglobulin, it can last about 28 days. Therefore, how long a tetanus shot lasts depends on the specific circumstances of the patient’s injection.

How long does it take for tetanus to develop?

The pathogen we refer to as tetanus is Clostridium tetani. It enters the body through broken skin or mucous membranes and proliferates extensively in an anaerobic environment, producing toxins that cause a characteristic infection known as tetanus. After infection, the incubation period of tetanus varies; typically, symptoms appear within seven to eight days, but they can manifest as quickly as within twenty-four hours or take several months or even years to develop.
