I was switched from a beta blocker to an ace inhibitor for hbp due to bad side effects. how long will it take for the cough with lisinopril?

10%: There is a 10% chance of getting a cough with lisinopril. That means there is a 90% chance of not getting a cough. Lisinopril is still very useful. Be optimistic that you are in the 90%.

About 10-12% of people taking an ACE inhibitor develop a cough, so taking one does not necessarily mean someone will develop a cough. If a cough does develop, it is typically dry with no mucus production and accompanied by a sore throat. Some people experience it within days, others 4 weeks, but there have been cases where the cough did not develop until 6-10 months or longer.
