After receiving a tetanus shot, it is generally advised not to consume alcohol in the short term. Alcohol should particularly be avoided on the day of the injection. This is because tetanus shots typically involve tetanus antitoxin, to which many individuals might have an allergic reaction. A skin test is required before the injection, and those who test positive are prohibited from using it. Drinking alcohol after receiving the tetanus shot can affect the effectiveness of the vaccine and increase the risk of delayed allergic reactions, therefore, it is advised not to drink alcohol on the same day. Moreover, tetanus shots are usually administered for deep wounds or heavily contaminated injuries, and consuming alcohol can hinder the healing of the wound. Thus, it is recommended not to drink alcohol on the day of receiving a tetanus shot.
