What is a potential side effect of anticholinergic medications used for overactive bladder?

Anticholinergic medications are commonly prescribed for overactive bladder as they help inhibit involuntary bladder contractions by blocking the action of acetylcholine at Muscarinic receptors. One of the notable side effects of these medications is blurred vision, which occurs due to the drug's ability to cause mydriasis (dilation of the pupils) and reduce the effectiveness of accommodation (the eye's ability to focus on near objects). This effect is particularly relevant as it can lead to difficulty in adjusting focus, contributing to visual disturbances.

Other side effects may include dry mouth, constipation, or urinary retention, but blurred vision specifically highlights the impact of anticholinergic properties on the eye. Understanding this answer is crucial for recognizing the broad range of side effects associated with treatment options, enabling healthcare providers to better inform patients about what to expect while on these medications.
