Tetanus injections are divided into tetanus toxoid, which requires a skin test, and tetanus immunoglobulin, which does not require a skin test. It is advised not to drink alcohol before receiving a tetanus toxoid injection, as alcohol can cause dilation of the capillaries throughout the body, leading to flushed skin, which can affect the outcome of the skin test and result in false positive or false negative results, impacting treatment. Wounds requiring tetanus injections are generally either very deep, severely contaminated, or involve an open fracture, typically indicating a severe wound. It is advised not to consume alcohol during the wound healing period to avoid delaying recovery. Therefore, alcohol should be avoided for 24 hours before the tetanus shot and during the subsequent recovery period of the wound.
