Efficacy and Tolerability Study of Betahistine to Ameliorate Antipsychotic Associated Weight Gain
United States48 participantsStarted 2008-07
Plain-language summary
The study attempts to evaluate a histamine analog long used for the treatment of Meniere's disease, betahistine, that shows promise in reversing the antihistaminergic effects thought to be involved in antipsychotic induced weight gain.
Hypothesis to be tested:
A. Patients who have gained a developmentally inappropriate amount of weight on antipsychotics (AP) will see their weight and BMI decrease with betahistine augmentation as compared to placebo augmentation.
B. Betahistine augmentation in AP treated patients will increase levels of satiety in a standardized meal situation and decrease caloric intake as compared to placebo augmentation.
C. Metabolic effects of betahistine augmentation in AP treated patients will be reflected in differences in waist circumference, hip circumference and waist hip ratios D. Betahistine augmentation in this population will lead to decrease in fasting glucose-lipid lab values related to the development of metabolic syndrome as compared to placebo augmentation

. The patient has had an increase of 7% of their weight during the last year while being treated with antipsychotics.
. The patient has a BMI of 30 or more and has gained 10 lbs or more in the past 8 months while being treated with antipsychotic medications.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
