Anticholinergic effects

Anticholinergic effects occur when medications block a chemical in the body called acetylcholine, which helps nerves communicate with certain organs. This can lead to side effects such as dry mouth, blurred vision, constipation, urinary retention, confusion, and increased heart rate. These effects happen because the drug interferes with normal nerve signals that control various body functions, especially in the nervous system. Anticholinergic effects are common with certain medications used for allergies, depression, and dizziness, and they vary depending on the dose and individual sensitivity.
