I took Lisinopril for over 9 months. In that time I lost a lot of weight, vomited up to 15 times a day, had a persistent dry cough and headache. My GP had no answers for me, sent me to specialists, etc. None of the medical professionals at that point could tell me what the cause was. ( I went from 200 pounds to 145 pounds, due to not being able to keep food or beverages down.) My teeth are permanently etched from stomach acid. I developed all sorts of other problems due to improper nourishment. During this time I had a total knee replacement.. thank goodness I had no complications due to the lack of being able to keep food down. My husband did an internet search on my blood pressure med ( lisinopril) and found this was a common side effect. I immediately made an appointment with my GP, who was away and another Doctor was standing in for him. She listened to my symptoms and said it was the lisinopril and to stop taking it immediately and prescribed something else. Within a week the cough and projectile vomiting was completely gone! What is the matter with the medical team? Why didn't one of them clue into this? Can't this droop be taken off the market or come with a warning on the pharmacy label?
