53 year old, otherwise healthy Type1 diabetic. HCA1 scores are typically 6.5-6.7. I lead an active, athletic lifestyle, with no circulation issues. Prior to Lisinopril, I have never experienced allergic responses to meds, hives or any similar issues. I have never experienced blood pressure issues; but Doc suggested Lisinopril for preventative maintenance, protecting kidneys. I took Lisinopril 5 mg. once daily, for almost 5 months without issues. In the middle of month 5, Urticaria appeared around mid-calf area, accompanied by a nerve-racking itch. In the next 2 weeks, itching started in hairline of scalp, moving spreading all the way down to ankles. I was almost 2 weeks into an elimination diet before discovering on a blog that urticaria was a possible side effect of Lisinopril. Discontinued Lisinopril 1.5 weeks ago, several days after starting 30mg Cetirizine & 30mg Loratadine [alternating every 3 days]. Itching is still present; but all urticaria have subsided, save for scalp. Menthol has been the only effective comfort for the itching. Prior to taking Lisinopril, my only urticaria experience originated from exposure to poison ivy. I am convinced Lisinopril is the root cause.
