Hi I Have Taken Lisinopril For Over 10 Years..on In

Hi I have taken Lisinopril for over 10 years..on in December 2010 I had swelling involving upper right lip only..took nothing it resolved itself..in February 2015 same area swelled up went to Urgent care given Benedryl 25 swelling went away next day..once again the same area swelled this February went over to ER no airway obstruction took benedry, steroid and Pepcid the swelling went away next day...now my primary care Dr. says it is Lisinopril related and gave me a script for amlodipine..I looked it up last night and see that people also have issues with allergic reactions to it too so what am I to do is it a 50/50 chance I will have a reaction to either med?
