A very common side effect is coughing fits.
I've been on it for years. I haven't experienced that possible side effect. I must be one of the lucky ones.
Hmm, No cough from Lisinopril, but I also take Albuterol Sulfate in 2 forms, Tudorza and Advair, along with other medicines. Could be why no cough. But, hey, at least I can walk distances good again! ;)
Then her doctor should put her on Losartan instead.
