Doctor put me on Lexapro 20 mg for a few weeks. I told her I didn't feel it was working as well as the 10 mg I was on. She said that she didn't think the Lexapro was helping me as well as she thought. Put me on Pristiq yesterday. I was always weaned off of medication until I went to her..what's up here?! I was always told it isnt safe not being weaned off.
