What is verapamil, and what is it used for?
Verapamil is a prescription medicine used to treat heart-related conditions. It works by slowing electrical signals through the heart and relaxing blood vessels, which can help control heart rate and improve blood flow [1].
Common uses include treating certain types of abnormal heart rhythms and managing conditions where controlling heart rate matters. It is also used for angina (chest pain) and high blood pressure in some patients [1].
How does verapamil work?
Verapamil blocks calcium entry into certain heart and blood vessel cells. This slows heart conduction through the atrioventricular (AV) node and reduces vessel contraction, which lowers heart workload and can reduce symptoms in people with rhythm problems or angina [1].
What forms does verapamil come in?
Verapamil is available in different formulations designed for different dosing schedules, including immediate-release and extended-release forms [1]. Extended-release products release the drug more slowly and are taken less frequently than immediate-release versions.
What side effects do patients ask about?
Patients commonly ask about side effects related to lower heart rate, blood pressure, and effects on digestion. Possible side effects can include dizziness, constipation, headache, swelling, and feeling unusually tired. Because verapamil can slow heart rate, clinicians monitor for symptoms like lightheadedness or fainting [1].
Who should be careful with verapamil?
Verapamil can interact with other medicines, including some heart drugs and medications that affect liver metabolism. It may also be risky in certain heart conditions where slowing conduction could worsen outcomes. Patients should discuss their full medication list with a clinician before starting or changing verapamil [1].
