I am a paramedic and run calls of people having these reactions a lot. It worries me that Docs do not discuss these possible reactions with their patients. Lisinopril is a decent drug to treat hypertension in itself. I have had patients who have been on Lisinopril anywhere from a month to several years. Yes, it is true that it can happen without any change in behavior, health or meds. We do treat it as an allergic reaction. We administer Benadryl per protocol but Benadryl really does nothing in these cases. It really is just a matter of managing the patients airway and waiting for the residual Lisinopril filter from the patient's system. Just be aware of this or talkj to your MD about switching to another HBP controller.
