I have been taking BP med's for may years now, and too have been ordered by my Dr's. to change from time to time. After many years on the same drug, I was ordered by my Dr. to change to Zestril, 20mg daily. I had absolutely no problems with that drug at all, but after only about 3 years was forced to change because of insurance company ignorance. I was then placed on Lisinopril 20mg, and within only a few months I've begun to lose my hearing in my right ear. I have a constant hissing/ringing in my right ear, and have been tested for hearing and told I have a 90% hearing loss in that ear. After reading some of the postings here, and elsewhere, I have found that Tinnitus is a definite side effect. Not only upset about all this, but angry that I didn't investigate earlier. Please be careful with med's people. Please pay attention to any and all side effects... Thank You
