Tetanus injections are a common preventive measure in daily life and are generally effective against tetanus bacillus infections. After receiving a tetanus injection, it is necessary to follow a specific diet. Typically, within a week of the injection, it is recommended to avoid spicy and irritating foods, as well as acidic foods. Beverages such as strong tea, coffee, and alcohol should also be avoided as much as possible. Additionally, foods that commonly cause allergic reactions, especially if one is usually allergic to certain foods, should be avoided under these circumstances. This is because if the immune system is weakened, the effectiveness against tetanus bacillus may diminish. Furthermore, it is crucial to get plenty of rest, drink more warm water, consume more fruits and vegetables, avoid strenuous activities, and avoid meat stimulants such as dog and lamb meat, among other considerations.
