Calan SR Singapore

Verapamil

What is Calan-SR used for?

Calan-SR (Verapamil) is typically used for treating conditions like hypertension (high blood pressure), angina (chest pain caused by heart disease), and certain heart rhythm disorders. It relaxes your blood vessels, allowing blood to flow more easily. This helps reduce the workload on your heart and increases the supply of oxygenated blood to the heart.

How does Calan-SR work?

Calan-SR is a type of medication known as a calcium channel blocker. It works by inhibiting the movement of calcium into cells of the heart and blood vessels. As a result, it relaxes the blood vessels, reduces the force and rate of the heartbeat, and controls the electrical activity in the heart, which helps regulate the heart rate.

What does the 'SR' in Calan-SR mean?

The 'SR' in Calan-SR stands for 'Sustained Release'. This means that the medication is formulated to slowly release the active ingredient, Verapamil, into your body over time. This sustained release allows for better long-term management of conditions.

How should I take Calan-SR?

Generally, Calan-SR should be taken orally, usually once or twice a day. However, the dosage depends on your medical condition and response to the treatment. It should be swallowed whole and not crushed, chewed, or broken due to its sustained-release property.

What are the potential side effects of Calan-SR?

Common side effects of Calan-SR include constipation, dizziness, nausea, and lightheadedness. More severe, although less common side effects, can include shortness of breath, irregular heartbeat, severe dizziness, and fainting. Patients should seek medical help immediately if they experience severe side effects.

Can I take Calan-SR if I have a history of heart disorders?

Individuals with a history of certain heart conditions, including heart failure or certain rhythm problems (such as sick sinus syndrome, second- or third-degree atrioventricular block), may be cautioned against taking Calan-SR. It is essential to discuss your personal and family medical history with your healthcare provider before starting this medication.

Can I consume alcohol while taking Calan-SR?

Alcohol can increase the blood pressure-lowering effect of Calan-SR, potentially leading to side-effects like dizziness, lightheadedness, and faintness. It's generally recommended to limit or avoid alcohol intake while on this medication.

Is it safe to take Calan-SR during pregnancy or while breastfeeding?

Before taking Calan-SR, pregnant women or women planning to conceive should discuss the potential risks and benefits with their doctor. Similarly, it's crucial to consult your doctor if you are breastfeeding or plan on breastfeeding, as this drug is known to pass into breast milk.

Can I stop using Calan-SR if my symptoms have improved?

Even if your symptoms have improved, do not discontinue using Calan-SR without consulting with your healthcare provider. Suddenly stopping the medication can exacerbate your condition, and withdrawal symptoms may occur.
