What is the definition or description of: bupivacaine allergy?

Same as any allergy : If there are hives/body or throat swelling/local rash / rapid heart beat, shortness of breath, low blood pressure after injection it MAY indicate allergy. BUT almost every time a patient tells me that we find the reaction was actually related to something mixed with the Bupivacaine ( like epinephrine etc) which can cause similar symptoms as a normal side effect hence important to clarify with doc.
