My prescribed dose of Venlafaxine i.e., 300mg/day - which I had been taking for approximately 5 years - was recently reduced by 75% to 75mg/day. This was apparently due to a clerical error (!). The amount was reduced in a single step (225mg), with no warning and without any explanation. Although I expressed my concerns regarding the matter, my GP/MD appears completely uninterested and my questions remain unanswered. Should I pursue an explanation or simply accept the situation and move on?
