What is a significant side effect of first-generation antipsychotics?

First-generation antipsychotics, also known as typical antipsychotics, are known to block dopamine receptors, which can lead to an increase in prolactin levels in the body. This condition is called hyperprolactinemia, which is characterized by elevated levels of the hormone prolactin. Prolactin is primarily involved in lactation and reproductive functions, and higher levels can cause a variety of symptoms, including galactorrhea (milk production not related to breastfeeding), amenorrhea (absence of menstruation), and sexual dysfunction.

The connection between the use of first-generation antipsychotics and hyperprolactinemia highlights the importance of monitoring patients for this side effect, as it can significantly impact their quality of life. This is particularly relevant in the treatment of conditions such as schizophrenia, where these medications are commonly prescribed. The management of elevated prolactin levels may involve switching to a different medication or implementing additional treatments to address the symptoms caused by this side effect.

In contrast, the other options provided do not align with the typical profile of side effects associated with first-generation antipsychotics. For example, diabetes insipidus is usually associated with a different class of medications or conditions. Weight loss is not
