Tetanus antitoxin medication serves a preventative function and is commonly used as a vaccine. Receiving a tetanus shot is essentially aimed at preventing infections from the tetanus bacterium. Generally, there are dietary restrictions to follow after getting the shot. The effect of this medication typically lasts about a week, during which it is necessary to observe these dietary restrictions. It is usually advisable to avoid spicy or cold foods, such as chili peppers, beef, lamb, dog meat, or seafood. These should be eaten sparingly or avoided altogether. Otherwise, these spicy foods might directly affect the efficacy of the tetanus antitoxin. In such cases, the prevention of tetanus infections could be significantly reduced, thereby increasing the likelihood of contracting tetanus bacterium.
