Frequently asked questions

What is Norpace New Capsule used for?

Norpace New Capsule is a medicine used to treat serious types of irregular heartbeats (called ventricular arrhythmias). These are heart rhythm problems that start in the lower chambers of your heart and can be life-threatening if not treated.

Who should not take Norpace New Capsule?

Individuals should not take Norpace New Capsule if they have cardiogenic shock (a condition where the heart suddenly can't pump enough blood to meet the body’s needs). It should also be avoided in those with second- or third-degree heart block without a pacemaker (a problem with the heart’s electrical signals), or congenital QT syndrome (a genetic condition that affects heart rhythm). Additionally, anyone allergic to disopyramide or any other ingredients in Norpace New Capsule should not use it.

What serious side effects of Norpace New Capsule should I watch for?

You should call your doctor right away if you experience serious side effects of Norpace New Capsule. These may include low blood pressure, a very fast or slow heartbeat (which could indicate a dangerous heart rhythm), or trouble urinating (a possible sign of urinary blockage). Other symptoms include dry mouth, blurred vision, or constipation, which may result from anticholinergic side effects—when a drug blocks certain nerve signals. Watch for signs of heart failure as well, such as swelling in the legs, shortness of breath, or sudden weight gain.

Should I be worried about low blood sugar while taking Norpace New Capsule?

Yes, Norpace New Capsule may cause low blood sugar (hypoglycemia), especially in people with diabetes. Symptoms include sweating, shakiness, confusion, and feeling very hungry. If you have diabetes, check your blood sugar regularly and talk to your doctor about adjusting your medication.

What should I tell my doctor before starting Norpace New Capsule?

Before starting Norpace New Capsule, you should tell your doctor if you have any heart condition (especially heart block, heart failure, or history of arrhythmia), diabetes, glaucoma (eye condition with high pressure), enlarged prostate or trouble urinating, and kidney or liver problems. This helps your doctor decide if Norpace New Capsule is safe for you.

How should I monitor myself at home during the treatment?

Your doctor may advise you a follow-up for a proper health assessment. However, you may perform daily checks such as pulse rate/regularity, weight (for fluid retention), urine output and blood pressure. Report it to the doctor in case of any fluctuation.

Does Norpace New Capsule cause dry mouth?

Yes, Norpace New Capsule may cause dry mouth in some individuals. Dry mouth is a common side effect of Norpace New Capsule. You may try candy or chewing gum to manage excessive dry mouth.

Can I stop taking Norpace New Capsule once I start feeling better?

No, never stop taking Norpace New Capsule on your own as it may worsen the condition. Your doctor may assess your response to the Norpace New Capsule and severity of the condition and may taper the dose of Norpace New Capsule. Typical tapering of dose over 2-4 weeks with continuous cardiac monitoring is essential.

Can Norpace New Capsule cause low blood pressure?

Yes, Norpace New Capsule may cause low blood pressure. Low blood pressure (hypotension) is the most common side effect of Norpace New Capsule treatment. Your doctor may monitor your blood pressure closely and may advise you to do so.

Does Norpace New Capsule cause constipation?

Yes, Norpace New Capsule may cause constipation. Constipation is a common side effect of Norpace New Capsule. You may include a fibre-rich diet to manage constipation. However, if this side effect bothers your well-being, ask your doctor for specific treatment.
