Chloe,
From my experience that "1 in 10" figure is a wishful-thinking joke

....Perhaps it's more like 1 in 10 cough so hard they have to be hospitalized and put on a ventilator.
If the ACE inhibitors weren't so cough-making, MANY more people would still be on them instead of on the much more expensive ARB's.
My cough got so bad on
Vasotec, I couldn't get a decent night's sleep because I kept coughing myself awake every couple minutes.
