Hi, I'm new here. Has anyone suffered from constant buzzing in the ear, after being on these. Both are known side effects of these drugs. I'm on 2.5 mg Bisoprol and 25mg Losarten daily. Saw 2 NHS Cardiologists and both are in denial. They said it could be something to do with my ears, not the drugs. I am awaiting a hearing test. However I got congenital nerve deafness in my left ear, since childhood,but no problems in my good right ear. Been on both drugs since beginning of 2015. Problem started about a year ago.
