I have been on ' Lexapro for 4 months after coming off of long term Prozac, which stopped working. I started with 10 mg and then to 20 mg of Lexapro. The result for me, is a feeling of dullness and chronic fatigue.
After a long consultation with my physician, I am weaning off Lexapro, and beginning Prozac again. My doc ordered a gene study for likely anti depressants and although Prozac was in the maybe range, it has worked for me in the past over the years. Lexapro was a top choice in the gene study. The best choice for for me according to AI, and the gene study seems to be Trintellix, which is $480 mo. With that said, I am passing and once again trying Prozac. Hope this helps someone.
