Chart comparing weight gain from antipsychotic drugs
Saturday, July 09, 2005 12:45 pm Email this article
Below is a chart comparing weight gain during the first two-and-a-half months from various antipsychotic drugs.
The chart below was redrawn from the paper referenced below (Newcomer, 2005).
Abilify less weight gain than Zyprexa (1.5 lbs vs 9.2 lbs)
Note that Abilify (aripiprazole) causes much less weight gain (1.5 pounds) after two-and-a-half months than Zyprexa (olanzapine) (9.2 pounds).
Abilify, first-line antipsychotic, comparable to Zyprexa in efficacy for a fair amount of patients, with less weight gain
I asked a psychiatrist who also specializes in weight loss if Abilify (aripiprazole) works as well as Zyprexa (olanzapine), and causes less weight gain.
Here is what he said.
“I believe Abilify is comparable to Zyprexa in its antipsychotic efficacy for at least a fair amount of patients. There’s definitely less weight gain, if any weight gain at all. I use it as a first-line antipsychotic.”

This is a very interesting chart. I gained 40 pounds on Zyprexa over 6 months and was so fed up with it that I requested a switch and was then prescribed Abilify. I almost threw up during the middle of the 1st night of taking the medicine, but am willing to go through the initial side effects to see if it improves my hypersomnia and weight gain.

Thanks for sharing your story.
Sorry to hear about your weight gain from Zyprexa.
A psychiatrist who also helps patients lose weight told me that Zyprexa is a miracle drug for certain conditions, but as the chart shows, Zyprexa is about as bad as it gets when it comes to causing weight gain.
