Verapamil
About Verapamil
Verapamil is used to treat hypertension (high blood pressure), angina pectoris, and arrhythmias. Hypertension is a condition in which there is a persistent rise in blood pressure levels. Angina pectoris (angina) is chest pain due to reduced blood flow to the heart due to blockage or narrowing of blood vessels supplying the heart. Arrhythmia is a condition in which your heart beats irregularly, too fast or too slow.
Verapamil contains ‘Verapamil’, which belongs to the class of ‘calcium channel blockers. It works by relaxing the blood vessels, decreasing the workload on the heart. It also increases the blood and oxygen supply to the heart, thereby normalizing the electrical impulses. These effects help to reduce blood pressure and also control the rate and rhythm of the heartbeat.
Take Verapamil as prescribed by your doctor. The common side effects of Verapamil are nausea, constipation, headache, dizziness, and low blood pressure. These side effects usually don’t require treatment and gradually resolve over time. However, if these side effects persist or worsen, inform your doctor immediately.
It is not recommended to take Verapamil if you are allergic to Verapamil or any other contents present in it, have heart failure or severe problems with the rhythm of the heart (unless you have a pacemaker), have heart failure and taking beta-blockers, have had a heart attack recently, have a history of bradycardia (slow heart rate) or hypotension (low blood pressure), have Wolff-Parkinson-White syndrome (rapid heart rate associated with dizziness), and have been taking a medicine containing ivabradine for heart diseases. Verapamil should be used with caution in patients with heart attacks and problems with the impulses in the heart, liver, and kidney diseases. Verapamil should be used with caution in pregnant women and is probably safe when used in breastfeeding mothers. Verapamil may increase the amount of alcohol in the body, so limit alcohol consumption. Verapamil may cause dizziness, so do not drive or operate heavy machinery if you feel dizzy.

Patients Concern
Disease/Condition Glossary
Hypertension: It is a chronic condition when blood pressure is too high. Blood pressure is the amount of blood pumped by the heart and the amount of resistance exerted by the arteries against the blood flow. If the heart pumps more blood, then arteries become narrower, and in turn, blood pressure becomes high. If blood pressure becomes uncontrolled, it may cause serious heart disease, including stroke and heart attack. High blood pressure also causes brain damage (stroke) and kidney failure. Blood pressure is expressed by systolic and diastolic. Systolic blood pressure represents the contraction and relaxation of the heart. Diastolic represents the pressure in the vessels when the heart beats and is in a resting state. Ideal blood pressure should be between 90/60mmHg and 120/80mmHg. Hypertension is detected when systolic blood pressure is more than 140mmHg, and diastolic pressure is higher than 90mmHg. Some symptoms of hypertension include headache, nose bleeding, vomiting, and chest pain.
Angina pectoris: It is the medical term for heart-related chest pain. It occurs when there is a reduction in blood supply to the heart due to the blockage of one or more arteries (coronary heart disease). Patients with angina often explain chest pain as squeezing, tightening, or pressure in the chest. Other symptoms can be dizziness, sweating, heartburn, and difficulty breathing.
Arrhythmia: Arrhythmia is a condition in which your heart beats irregularly, too fast, or too slow. Symptoms of irregular heartbeat include chest pain, shortness of breath, and fast or slow heartbeat. 60 to 100 beats per minute is generally considered a normal heart rate.
