Ever since I started on Lisinipril I have had a constant cough, doctor did change me to Losartan, but wanted me to return to Lisinipril. He insists that my cough is not caused by medication but that I have asthma which produces the cough. He has put me on inhalers, but I now have insomnia, lost weight and feel like I am not being diagnosed correctly. I am one that never on any type of meds before my diagnosed HBP in October 2014. I have been miserable ever since. Any body out there with same problem?
