While on Effexor I developed difficulty hearing to the point where I had trouble understanding what people were saying if there was a lot of ambient noise. I also had trouble hearing on the phone. I experienced a great deal of "hissing" in my ears to go along with the Effexor induced brain zaps. After discontinuing Effexor five months ago, my hearing improved to the point where I'm not so hindered by ambient noise & it's easier to hear on the phone. Unfortunately, the hissing sound (kind of like a cross between the sound of high power lines and the sound of soda pop bubbles hissing in a can) is still with me & it's quite bothersome. Has anyone else experienced hearing problems caused by Effexor? If you had hearing problems caused by Effexor and are now off Effexor, did your hearing return to normal and if not, what happened? Did your doctor give you any insight to the problem? Thanks!
