Hi. I was also prescribed Effexor for perimenopause. It helped with night sweats and palpitations , but only a few weeks in I started to experience extreme ear pressure, ear infection and inflammation. Now tapering off and wow it’s awful. Sweating, brain zapping, vertigo, nausea… and I was only on 37mg. Worst part is both my family and Gyno doc say NONE of it is from Effexor. Ear pressure reduced only day two of weaning, and slowly other symptoms slowing with second week of tapering down. Coincidence, I think not.
