What is a common side effect monitored during antiemetic therapy?

A common side effect monitored during antiemetic therapy is dry mouth. Many antiemetic agents, particularly those that are anticholinergic in nature, can inhibit salivation and cause xerostomia (dry mouth). This side effect can significantly affect a patient's comfort and may lead to difficulties in swallowing or an increased risk of dental issues if not managed properly. Monitoring for dry mouth is important to ensure that patients maintain oral hygiene and stay hydrated, thereby preventing complications associated with this side effect.

While weight gain, headaches, and skin rashes are certainly possible side effects of various medications, they are not as commonly associated with antiemetics in the same way that dry mouth is. Dry mouth is a well-recognized and frequently reported effect related to particular classes of antiemetics, making it critical for healthcare providers to assess and address this concern during therapy.
