Which of the following is a common adverse effect associated with Verapamil?

Verapamil, a calcium channel blocker commonly used to treat conditions such as hypertension and angina, is known to have constipation as a common adverse effect. This occurs because verapamil can lead to decreased gastrointestinal motility due to its effects on smooth muscle contraction. By blocking calcium channels in the walls of the intestines, verapamil reduces peristalsis and can result in slower transit of stool, ultimately leading to constipation. Understanding this specific side effect is crucial for both patient management and education, as it enables healthcare providers to offer lifestyle recommendations or adjunct treatments to alleviate this discomfort for patients who may be affected by it.
