I have been complaining to my Doctor about prolonged coughing that has lasted over 8 months. The cough is so bad that it causes me to vomit periodically. I was put on two different antibiotics told that I may have whooping cough and the only thing that helped the cough was tussinex cough medicine that was very expensive. Whooping cough was ruled out by health department. I told the doctor I could not keep taking the cough medicine so he tried another cough medicine that did not help. A friend told me yesterday that he knew a friend that had a similar cough caused by his blood pressure medicine so I came home and started researching the net and found this site that has really opened my eyes. I called my doctor but he has not returned my call yet. After reading this information I may have had another side effect of this medication Lisinopril of which I felt like I was going to pass out sitting at my computer one day. I hope that I find out the cough was caused by this medicine because it has literally wore me out coughing so much. I have pulled abdomen muscles from coughing so hard and told the doctor but he has never mentioned it could be related to Lisinopril.
