Yes, what you are describing can happen and is quite common in the early phase of antidepressant treatment. Nexito (escitalopram) often improves anxiety first. Mood improvement usually takes 4–6 weeks. It is common to feel better initially and then feel low again for some time before the medicine fully settles.
This does not mean the medicine is failing. Sometimes the dose needs adjustment, or stress and sleep issues can affect mood.
Next Steps
Please do not stop or change the dose on your own.
Follow up with your psychiatrist for review.
