I was on viibryd 40 mg a while back. My husband noticed one pupil was bigger than the other. I freaked out went to the eye doctor who found nothing wrong and I probably always had it. I thought the viibryd made it worse so I lower the dose to 10 mg. it never quite went away. Now that my anxiety has worsened. I was to increase the viibryd back to 40. However at 20 mg the eye thing is back. I want to stick with viibryd but this eye thing worries me. Has this happened to anyone else?
