I started taking Lisinopril only a week ago. After four days I had to stop. I have high BP and asthma. I was originally given a diuretic, but my BP only came sdown slightly, so my doctor prescribed 5mg of Lisinopril a day. The first day I had blurred vision and a slight cough. By the fourth day I was hacking so badly I nearly dialed 911. It was like one of my bad asthma attacks only 10,000 times worse. The next day I didn't take the Lisionpril. I called my doc and she told me to just stick with the diuretic until my next appointment in two weeks. It's now been two days since I've taken any Lisinopril and I still can't stop coughing. Be careful and ask questions before taking this medication.
