What is a common side effect of Risperidone related to hormonal changes?

The common side effect of Risperidone related to hormonal changes is galactorrhea. This condition involves the inappropriate secretion of breast milk and can occur due to the medication's influence on prolactin levels. Risperidone, an atypical antipsychotic, blocks dopamine receptors in the brain, specifically D2 receptors. When dopamine, which normally inhibits the secretion of prolactin, is blocked, it can lead to an increase in prolactin levels, resulting in galactorrhea.

This side effect highlights the importance of monitoring hormonal changes in patients treated with antipsychotic medications, as increased prolactin can also lead to other issues, such as menstrual irregularities in women and gynecomastia in men. Understanding the link between Risperidone and its effects on prolactin helps clinicians provide better care and manage potential side effects effectively.
