I had been on Lisinopril for nine months when I developed a sinus condition which appears to be attributed to allergies. I have not had allergies before. My doctor put me on Flonase, Singular and Zrytec to alleviate the sinus condition but after three months I still am plagued with it. I am now having a terrible time with sleepliness. Prior to the sinus condition I developed a tickle in my throat that lead to frequent coughing. I asked my Doctor if Lisinopril could be causing these problems and his answer was negative. I am going to tell him to get me off this medication.
