Which of the following side effects is frequently associated with CCBs?

Calcium channel blockers (CCBs) are a class of medications commonly used to treat conditions such as hypertension and angina. A frequently reported side effect of CCBs is headaches. This can occur due to the vasodilatory effects of these drugs, which can lead to a decrease in peripheral vascular resistance. As blood vessels dilate, this can sometimes trigger headaches, particularly in the initial stages of treatment or when the dosage is adjusted.

Headaches are considered a common side effect because they can occur in a significant number of patients taking these medications, making them a known and expected reaction to CCB therapy. Understanding this helps healthcare providers manage side effects and educate patients appropriately about what to expect during treatment.

While other side effects associated with CCBs may exist, such as potentially causing nausea or vision changes, these are not as frequently reported or specific to CCB use as headaches.
