I went on Lisinopril about 3 months ago and for about that amount of time have had a terrible dry cough; I went to my doctor who told me I probably had allergies and suggested Claritin, which did not help. So, I suffered with this cough which is so bad sometimes I gag. I knew something was up because I've never had a cough that was dry this way. Plus, I kept asking people what their allergy symptoms were and they kept saying sneezing and running nose and I didn't have any of those. So, I went to an allergy doctor who concluded that I did not have any allergies and highly suspected the Lisinopril. He told me to quit taking it since my BP was now so low (110/74) and if it goes back up and can go back on something; I still take hydrochlorot. I was thrilled because I've never had allergies and sure didn't want to have them now. We'll see if this does the trick. BTW, sometimes I get these attacks at night when I first go to sleep and lay on my side. Hope this helps someone.
