Additionally, some mental health conditions may make it difficult to stay active and eat a nutritious diet. These issues may compound an antipsychotic’s effects on weight and appetite control.
Many people see their weight increase once they begin taking antipsychotics. While weight gain may continue in the long term, it typically decreases and eventually plateaus.

Living with the social stigma of weight gain

- haloperidol (Haldol)
- lumateperone (Caplyta)
- lurasidone (Latuda)

When to talk with your doctor
If your doctor recommends antipsychotics, start talking about weight gain right away. Some doctors do not consider the implications of weight gain for their patients. That’s why it’s important to voice any concerns or questions as soon as possible.
If you have just started taking an antipsychotic, or even if you have been using one for a while, it’s not too late to talk with your doctor about side effects.
Weight gain is rapid in the first few weeks after starting these medications, but it can continue for months or years. Understanding possible treatments and interventions will help you stop or prevent more weight gain.
Important: Do not stop or cut back on any prescribed medications without first talking with your doctor. Doing so could cause symptoms to return. It could also set back the treatment of your mental health condition.
Weight gain when taking antipsychotic medication is a serious concern for many people. The risk of weight gain is highest in the first months after beginning the drugs, but weight gain can continue for a year or longer.
Early intervention and prevention are key to reducing the effects these medications may have on your weight.
Talk with your doctor if you’re going to take or are currently taking this type of medication. You may be able to work together to change medications and dosages, if needed. You can also try different lifestyle strategies that may help reduce the risk of weight gain and associated health issues.
Some weight gain is a well-understood and acceptable side effect of these important medications. For the sake of your mental health, never stop taking these medications unless instructed to do so by your doctor.
