After tendon rupture, alcohol is not allowed for the following two reasons: First, after tendon rupture, the tendon is surgically treated to restore the continuity of the tendon, and after surgery, external fixation in plaster is performed, and cephalosporin antibiotics are routinely applied after surgery to prevent wound infection, and cephalosporin antibiotics commonly react with alcohol in a disulfiram reaction, with clinical manifestations such as skin papules, chest tightness, shortness of breath, panic, dyspnea, and in severe cases, loss of consciousness Therefore, alcohol consumption is not allowed during cephalosporin medication, and alcohol consumption is allowed only 2 weeks after cephalosporin is discontinued. Secondly, after tendon rupture surgery, there will be a small amount of blood leakage in the wound for a short time, such as drinking alcohol, which will cause the blood vessels to expand, resulting in increased bleeding in the wound and the formation of local hematoma, which can lead to secondary wound infection.
