I am a 60 year old female. Had taken Hyzaar for several years, but due to high cost, insurance recommended Lisinopril (my doctor agreed). I started taking Lisinopril HCTZ 20/25mg on 5/11/08. After 5 days, I developed a cough that grew increasingly worse with lots of mucus. I coughed so hard there would be tears rolling down my face. The mucus would get stuck in my throat and I had to make horrible sounds to clear it. I carried a bottle of water every where. I saw my doctor on 5/27/08. He prescribed antibiotic for sinus infection and cough med. The meds did not help. I saw him again on 6/2 and 6/5 and he gave me a steroid that did not help. I started researching side effects of Lisinopril and decided to take myself off on 6/12 and start the Hyzaar again. In the meantime my doctor got me in to see an ENT on 6/17. He gave me a nose spray and something to dry up the mucus. I noticed the cough did not seem as bad the day I went to the ENT and it got progressively better. I did take the medication prescribed by the ENT, but felt that discontinuing the Lisinopril was probably why the cough and mucus got better. So, a "glutton for punishment", I started the Lisinopril again (wanted to make sure my problems were caused by the Lisinopril). After taking it for about 6 days, I have developed the cough and mucus again. No more Lisinopril for me. I started Hyzaar again on 7/6. It took about a week to a week and a half last time to get better.
