Hi there, my mother is taking atenolol 50 mg every morning for many years, and about 2 weeks ago, the doc increased her dosage from 50 mg/day to 75 mg/day (25 mg to take in the evening). Also, he added lisinopril 5mg/day two weeks ago as well. One weeks ago, she started dry cough . Not a lot, but it was bothering her. So the doc stopped lisinopril and changed to losartan (12.5 mg/day). She started the new med (along with atenolol) last Friday, and instead bringing down her blood pressure and heart rate , the readings actually went up. She started cough again in the afternoon on Sat., and by Sunday afternoon, she lost her voice, and she complained about shortness of breath. Does this sound like she is allergic to losartan? We were told losartan is more gentle than lisinopril...
