I have been on lisinopril for 3-4 months. For the past 4 weeks I have had a dry cough and was treated for bronchitis. Last night was taken to the emergency room, because I was coughing, gagging, throwing up balls of mucus and not being able to catch my breath, feeling my throat was closing. They checked me out and felt it was a reaction to ACE inhibitors. Took me off and are treating with new blood pressure medication. They said it would take at least 4 days to see a difference.
