Which side effect is associated with Risperidone?

Massive weight gain Slows HR Gynecomastia and lactation Must be taken with food for efficacy

Correct Answer:

Gynecomastia and lactation

Explanation:

Risperidone can raise prolactin levels because it blocks dopamine D2 receptors, including in the tuberoinfundibular pathway that normally keeps prolactin in check. When this dopamine inhibition is blocked, prolactin secretion increases, leading to breast tissue growth and milk production—gynecomastia and lactation. This hormonal effect is a hallmark of risperidone’s side effects, making it the best choice. Weight changes can occur with antipsychotics, but “massive weight gain” isn’t the most characteristic side effect of risperidone. Slowing the heart rate isn’t a typical or defining effect of this medication, and risperidone does not require taking with food for efficacy; it can be taken with or without food.
