Sex-related differences were especially pronounced for hyperprolactinemia, with 4.7–8.0 times higher reporting odds in women for aripiprazole, olanzapine, quetiapine, and haloperidol—except for risperidone, where a post-2014 rise in male reports led to higher odds in men. Risperidone was also associated with increased reporting odds of weight gain in men.
