Which of the following indicates an adverse effect of desmopressin acetate?

Desmopressin acetate is a synthetic analog of vasopressin and is primarily used to manage conditions like diabetes insipidus and certain bleeding disorders such as hemophilia. Understanding the pharmacological effects of desmopressin can help identify its adverse effects.

Drowsiness is recognized as a potential adverse effect of desmopressin acetate. While many patients may tolerate this medication without significant issues, some individuals might experience sedation or drowsiness, which can interfere with daily activities. It is crucial for healthcare providers to monitor patients for this side effect, particularly because it can affect their overall functioning.

Increased urination is often an expected outcome of desmopressin use, especially since it acts on the kidneys to promote water reabsorption and decrease urine output. Similarly, insomnia and weight loss do not typically relate to desmopressin’s pharmacological action or its adverse effect profile. Instead, these would be considered atypical responses and are not commonly reported in association with this medication. Therefore, drowsiness is the most relevant adverse effect linked to desmopressin acetate.
