Calaptin 120mg SR Tablet contains verapamil, a calcium-channel blocker used to manage certain cardiovascular conditions, including high blood pressure, angina, and some abnormal heart rhythms. The “SR” designation refers to sustained release, meaning the medicine is formulated to release verapamil gradually rather than all at once.
If your doctor has prescribed Calaptin 120mg SR Tablet, taking it consistently can help keep your blood pressure under better control, reduce the frequency of certain types of heart-related chest pain, or help control selected fast heart rhythms. The exact reason for treatment depends on your diagnosis, other medicines, heart function, and overall health.
How Calaptin 120mg SR Tablet Works
Calaptin 120mg SR Tablet works by reducing the movement of calcium into certain heart and blood-vessel muscle cells. This action relaxes blood vessels, allowing blood to flow more easily and reducing the workload placed on the heart. Verapamil also slows electrical conduction through the heart, which can help control certain rapid heart rhythms.
Because verapamil affects both blood vessels and the electrical activity of the heart, doctors select it carefully according to the patient’s condition. This is also why you should not change the dose, combine it with other heart medicines, or discontinue treatment without professional advice.
Uses and Potential Benefits
Doctors may prescribe Calaptin 120mg SR Tablet for hypertension, or high blood pressure. By relaxing blood vessels, verapamil can lower pressure within the cardiovascular system. Consistent treatment, together with appropriate diet, exercise, weight management, and other prescribed medicines, can help reduce the long-term risks associated with uncontrolled blood pressure.
Doctors may also use Calaptin 120mg SR Tablet to prevent or reduce episodes of chronic stable angina. Angina occurs when the heart muscle does not receive enough oxygen-rich blood for its needs. Verapamil can reduce the heart’s workload and improve blood flow, helping prevent certain episodes of heart-related chest discomfort. It is not a treatment for a sudden or emergency episode of chest pain.
Another important use of Calaptin 120mg SR Tablet involves certain abnormal heart rhythms. Verapamil can slow conduction through the atrioventricular node and may help control the heart rate in selected supraventricular arrhythmias. A healthcare professional should determine whether verapamil is appropriate for a particular rhythm disorder.
How to Take Calaptin 120mg SR Tablet
Take Calaptin 120mg SR Tablet exactly as prescribed. Because this is a sustained-release formulation, swallow the tablet whole with water unless your specific product information says otherwise. Do not crush or chew an SR tablet, because doing so can interfere with the intended release of the medicine.
Take your dose at the time recommended by your doctor. If you forget a dose, follow your pharmacist or prescriber’s instructions rather than taking extra medicine to compensate. Never increase or decrease the dose because your blood pressure or heart rate appears better or worse.
Do not suddenly stop Calaptin 120mg SR Tablet unless your healthcare professional tells you to do so. Stopping cardiovascular treatment without medical guidance can allow the underlying condition to become uncontrolled.

Common Side Effects
Like other medicines, Calaptin 120mg SR Tablet can cause side effects. Commonly reported effects include constipation, dizziness, headache, nausea, fatigue, low blood pressure, and swelling of the ankles or legs.
Many mild effects improve as the body adjusts to treatment, but you should tell your healthcare professional if symptoms persist, become troublesome, or interfere with daily activities.
Seek prompt medical attention if you experience fainting, severe dizziness, unusually slow or irregular heartbeat, worsening shortness of breath, or rapidly increasing swelling. Verapamil can affect heart rate and electrical conduction, so serious symptoms require medical assessment.
Precautions and Drug Interactions
Before starting Calaptin 120mg SR Tablet, tell your doctor about all medical conditions and medicines you use. Particular caution may be necessary in people with low blood pressure, certain conduction abnormalities, slow heart rate, heart failure, liver problems, or kidney impairment.
Verapamil can interact with numerous medicines. For example, combining it with beta-blockers can produce excessive slowing of the heart or impaired electrical conduction in some patients. Verapamil is also metabolized through CYP3A4, so medicines that inhibit or induce this enzyme can alter verapamil concentrations.
Grapefruit juice may increase verapamil concentrations, so discuss grapefruit or grapefruit juice consumption with your pharmacist or physician.
Tell your healthcare professional if you are pregnant, planning pregnancy, or breastfeeding. They can determine whether verapamil is appropriate for your circumstances.
Ordering and Responsible Use
If your healthcare professional has prescribed Calaptin 120mg SR Tablet, use a legitimate pharmacy and verify the medicine, strength, packaging, and expiry information before use. Because this is a prescription cardiovascular medicine, purchasing it should follow applicable prescription and pharmacy requirements.
Do not purchase Calaptin 120mg SR Tablet simply because someone else takes it for blood pressure, chest pain, or an irregular heartbeat. The correct medicine and dose depend on the individual’s diagnosis and medical history. A pharmacist can also help check potential interactions with your existing medicines.
