I am on 20 mg escitalopram for chronic anxiety. The anxiety is something in my system since childhood. I am 54 years now.I started with 5 mg for one week , 10 mg for 4 weeks and now I am in my fourth week of 20 mg. Everytime I up the dose, i feel better for a week and then the medicine stops being effective.My doctor says , we will try another medicine, something like Pristiq.
Any suggestions on the subject please.
