Risperdal and Weight Gain

Is there a connection between Risperdal and weight gain? Studies have shown that up to 5 percent of people taking Risperdal reported weight gain as a side effect of the medication. While a small amount of weight gain is typical when taking Risperdal, some people can gain very large amounts of weight while taking the medicine.

 

Does Risperdal Cause Weight Gain?

Weight gain is a common side effect of Risperdal® (risperidone). Weight gain with Risperdal occurs in up to 5 percent of people. While a small amount of weight gain (about one pound) is typical during treatment with Risperdal, some people can gain very large amounts of weight while taking the medication. This weight gain is thought to increase the risk of diabetes (see Risperdal and Diabetes) or other health problems. Therefore, if you are noticing a rapid or large increase in weight while taking Risperdal, make sure to talk with your healthcare provider.
