About how long a tetanus shot lasts, it generally lasts from half a year to a year without any issues. So, if there is a wound, it is crucial to go to a surgical department for wound debridement and disinfection as soon as possible, especially after rinsing with hydrogen peroxide, keep the wound clean and dry. Secondly, change dressings. Generally, if it is not an infected wound, change the dressing every 1 to 2 days, and if infected, change the dressing daily. If necessary, take oral antibiotics to prevent infection. If you are not allergic to cephalosporins, it is usual to take some cephalosporin-based medications. Afterwards, be mindful of your diet and avoid spicy and irritating foods, and have regular check-ups.
