As with nearly any medicine, taking phytonadione could trigger an allergic reaction. This occurs because your immune system treats the medicine, or any ingredient used in the preparation you are taking, as a potentially harmful substance. The immune system attack results in symptoms that can be mild or serious. If you take phytonadione and notice your eyes are itchy or you get a rash or even hives, you are probably having a mild allergic reaction. However, if you begin noticing that your lips or tongue are swelling or you are having difficulty breathing, you may be having a potentially dangerous allergic reaction called anaphylaxis. Call 911 or get to an emergency room as quickly as you can.
