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.
