Hi SheriA-
I can only speak for the amitriptyline. I have been on amitriptyline 20 mg for the past 2 months and it made me gain weigh but not as rapid as yours. I plan on getting off of it as soon as I am able. My thoughts are with you. Hope you find your answer:)

Unfortunately, both can cause weight gain. Just try to stay as active as possible.

One, either, or both. If the weight gain is nor excessive, and 10lbs is not, you may have to opt for mental health and happiness over vanity.
I gained weight on some other medications and I love ever pound of it because I am happy, functional, and productive
Best wishes, WCV

It's Elavil! Same thing happened to me in 1981! When I mentioned to my psychiatrist this last November that I slept so well with Elavil, maybe I could now? He answered that I probably would, but the unfortunate side effect would most likely be weight gain. I believe it cures your depression so effectively that your appetite increases? think I read that somewhere among my many many medical newsletters...

SheriA; here are some uncommon/ Rare side effects on Gabapentin(((unexplained weight loss***
voice changes
vomiting
weakness or loss of strength
weight gain****** OKAY CHUCK AGAIN!!! Amitriptyline under common is weight gain!!! ***** when I was on both of these at the same time it was the Amitriptyline that I gained weight from not the Gabapentin it is known more as a WEIGHT NEUTRAL MEDICATION WHEN BOTH ARE LISTED GAIN AND LOSS MOST PEOPLE STAY ABOUT THE SAME WEIGHT. just my personal feeling is you might be able to control the gain a lot of people do it by adjusting what they eat, Small walks, and less red meat. BUT AT 5lbs a week none of us could handle that for long. You think it over and talk with your doctor before you end up with at least 60lbs a year. There are a lot of good medications that well help you sleep that you don't have to worry about gaining weight.if that is a problem.

Hi Sheri,

I was prescribed Elavil for chronic pain (along with 100 mg. Gabapentin, in 2013) but the Elavil made me so crazy I stopped them both. I gained a great deal of weight on the Elavil, I even would eat dinner and then eat another one. I was so ravenous I think I would ave eaten a piece of cardboard had you put some cream cheese on it!! It also gave me many more bad side effects, but you're only asking about the weight gain, so I won't take up space with all the rest. This past year I got a new PCP who put me on 600 mg. of Gabapentin 3X a day, and it isn't having that effect on me, (although I think I do lot of "comfort" eating, so I fluctuate,) but the Gabapentin actually improved my mood for a long time.

Both drugs are reported in the PDR as having a very slight potential to cause weight gain (Gabapentin 2.9% and Elavil 3.8% of users).
Of course those figures are not of much comfort if you happen to be in those percentile groups. :-(
