I have been prescribed mirtazapine 15mg. I am really worried about huge weight gain. Help!?

15 mg and below induce more sleep, etc. Higher doses 30 and up are more energizing. All this said,
I've been on 15 mg mirtazapine for years and never gained more than maybe 3-4 lbs. It does increase appetite, but it does not alter your metabolism in ways that make weight gain difficult if not impossible to control (like the antipsychotics do). So, don't fret over mirtazapine and take the dose your Dr. recommends.

Hi, rstoltzm!
Only about 10% of users will experience any weight gain and it's dose dependent. But everyone responds to these medications differently so it's impossible to determine what dosage might cause you to gain weight... if you gain any at all. Even if you do the average weight gain is 2kg or 4.5 pounds. In comparison to other classes of antidepressant/anxiolytics the atypical mirtazapine is relatively weight neutral.
I wouldn't be overly concerned.

Hi,
I can’t add anything more than the excellent responses already given to you.
I was using it for insomnia and I did gain weight.
I was so sleep deprived nothing else mattered. Obviously, it didn’t work for me.
However...
It wouldn’t have happened if I weighed myself daily! Be aware of everything you put in your mouth!
You will do well!
Best wishes,
:-)
