Why does doxepin cause weight gain? Does it change your metabolism in any way?

I've been on doxipin for 8mths and have gain 30 lbs. it so frustrating . He now has my on a lower dose, but I'm also on lamectal that has the same effect.

Also try to get him to give you klonepin at night. Good sleep

I have gone from 25mg to 10 mg of doxepin at night for 2 weeks now. I also, take Clonazepam with it. I am sleeping well. I started Pristiq 100 mg the same time I started the Doxepin 25 mg almost 2 years ago. I gained 45 pounds. I was able to cut the Pristiq in half to 50 mg about a year ago. That did not help the weight situation. Now I am off the Pristiq and on Wellbutrin 300 mg as of 2 weeks ago. My doctor wants to change me off the doxepin to Trazadone but I've taken that before and it makes me too drowsy in the AM. What could I change to instead of the Trazadone? I have been on many different drugs over the years.

I'm on 50mg of Doxepin at night. I sleep great but i've started gaining weight, about 10 lbs now over 3 months. I didn't take it last night and i feel less hungry today. I'm definitely talking to my doctor. I just lost that weight and gaining it back wasn't fun.

Yep I gained weight too on doxepin and it happened SO fast. 20 lbs. in 2 months! I was in denial at first thinking that my clothes had shrunk when I washed them. So I just kept telling myself that's what it was. I mean I've been on the thin side my entire life. It wasn't until I couldn't fit into most of my clothes that I finally stepped on the scale. I immediately stopped taking the doxepin and fortunately the weight gradually started to drop off over the following months. Anti-depressants caused gradual weight gain too although much slower so I stay away from all of those medications. Make sure you keep a constant eye on your weight if you're prescribed to any of these medications because the weight will creep up on you quickly.

I have been taking 25mg of doxepin and 10 mg paxil for one month and ive gained 12lbs. Im tall but i went from 167lbs at the doc apt where he prescribed doxepin to 178lbs at my doc apt last week. Doxepin does not help me sleep as promised so I recently found somnapure (a mix of natural supplements) at walgreens and its the only thing I've found that works and I love it. It makes me fall asleep and i have a deep sleep for at least 7-8hrs. They don't have it at walmart so check Walgreens, cvs, or Amazon. I have tried all the z-quil, unison, benedryl types; melatonin by itself, lunesta, seroquel(which knocks me out but lingers all day, hated it; it also gives bad sinus effects about 25 minutes after taking it). I thought it was the paxil making me gain weight but now that im reading more, it may be doxepin. I worked hard to get my weight down so I'm going to decrease my dose starting tonight and get off of it. I cant handle the weight gain.
