Thanks for your query. Nexito
is escitalopram, a SSRI
anti-depressant. It is indeed theoretically associated with weight gain though clinically it is generally insignificant. I would suggest you make appropriate dietary modification after discussion with your dietician as well as daily graded exercises to cut down your weight. Also periodically you need to monitor your weight.
I would not suggest a change in antidepressant for this side effect provided your depression
has shown significant response. Hope you found the information useful.
