Penicillin allergy can cause symptoms such as difficulty breathing and palpitations. The main manifestations of penicillin allergy include angioedema and anaphylactic shock, with anaphylactic shock being a rapid, IgE-mediated allergic reaction. Shock symptoms such as palpitations, chest tightness, difficulty breathing, cold extremities, cyanosis of the lips, decreased blood pressure, and coma can lead to death within a very short time.
