I have been taking venlafaxine for one month and have seen no improvement in my depression or anxiety? I started off taking 37.5mg for one week and then for the last 3 weeks I have been taking 75mg. I am still experiencing some unpleasant side effects and that's been a month on the drug. I do not know if everything I am experiencing is caused by the venlafaxine but here is some of the things I have been experiencing Increased social anxiety, dry mouth, sore mouth, sore eyes, nausea, sexual difficulties and constantly feeling tired. I have also not ever been wanting to do anything or go out anywhere. I have been on different anti depressants in the past and most side effects wore off within a few weeks. But with the venlafaxine after a month a lot of the side effects still seem to be going strong. Do you think I just need more time on the venlafaxine? I'm not sure what to do as I feel worse than before I even started taking it.
