What is a common side effect of anticholinergic medications?

Anticholinergic medications are known for their ability to block the action of acetylcholine, a neurotransmitter involved in various bodily functions, including salivation and secretions. One of the primary side effects associated with the use of these medications is dry mouth, also known as xerostomia. The anticholinergic effect reduces saliva production, leading to a feeling of dryness in the mouth, which can be uncomfortable for patients.

This side effect is not only common but can also impact a patient's quality of life, as adequate saliva is important for digestion and oral health. While other side effects like increased heart rate or changes in mucous production may be associated with different classes of medications, the dry mouth side effect is particularly characteristic of anticholinergics and is frequently noted in clinical settings. Other options either represent effects not typically associated with anticholinergic medications or involve physiological responses that are not a direct result of the anticholinergic action.
