What is a common side effect of the scopolamine patch, particularly in the elderly?

Nausea
Dry mouth
Headache
Diarrhea

The correct answer is: Dry mouth

The scopolamine patch is primarily used to prevent motion sickness and postoperative nausea. One of the well-documented side effects of scopolamine, especially notable in elderly patients, is dry mouth. This occurs due to the anticholinergic properties of the medication, which inhibit the secretion of saliva and other fluids in the body. In older adults, who may already have reduced salivary function or other comorbidities that affect hydration and mucosal health, this side effect can be particularly concerning. It may lead to discomfort, difficulty in swallowing, and increased risk of dental issues or oral infections. Understanding this side effect is crucial for healthcare providers when prescribing scopolamine, as they need to monitor elderly patients closely and provide education regarding hydration and oral care to mitigate the risk of complications associated with dry mouth.
