What common side effect should an adult client receiving hydroxyzine for nausea be monitored for?

Hydroxyzine, an antihistamine with antiemetic properties, frequently causes dry mouth as a common side effect. This occurs due to its anticholinergic properties, which inhibit saliva production. It's important for patients receiving hydroxyzine to be monitored for this side effect as it can lead to discomfort and potential complications like dental issues if not managed properly.

While other side effects, such as drowsiness, can also occur, they may not be as universally experienced in every patient. Constipation is less commonly associated with hydroxyzine compared to dry mouth, which is a direct result of its mechanism of action. Nausea is the symptom being treated, so monitoring for it is not necessary in this context. Therefore, focusing on dry mouth is essential for providing holistic care to patients taking hydroxyzine for nausea.
