Indications
Norpace CR is a medication used to treat certain types of serious irregular heartbeats, such as sustained ventricular tachycardia. It can be used to restore normal heart rhythm and maintain a regular, steady heartbeat.
Norpace CR is an anti-arrhythmic drug that is used to restore and maintain a regular, steady heartbeat. The active ingredient in Norpace CR is disopyramide phosphate. Disopyramide is in a class of medications called antiarrhythmic medications. It works by blocking certain electrical signals in the heart that can cause an irregular heartbeat.
Use and Dosage
Norpace CR is available as capsules that should be taken by mouth either with or without food, usually twice a day as directed. Take the medication exactly as prescribed, even if you feel fine. The extended-release capsules should be swallowed whole, and not crushed or chewed, to prevent the drug from being released all at once, which can cause side effects. The capsules can be taken with or without food, but some people find taking it with food or milk can help avoid stomach issues.
Dosages may vary depending on the individual and their medical condition and should be determined by a healthcare provider. The usual recommended adult dosage range for Norpace CR is between 400 to 800 mg per day, given in divided doses. However, the recommended dosage for most adults is 600 mg per day, taken in divided doses of 150 mg every 6 hours.
Use Norpace CR regularly to get the most benefit from it, so try to take the medication at the same time each day to help remember. Do not take Norpace CR to treat any heart rhythm disorder that has not been diagnosed by your doctor. If you are unsure about how to take your medication, speak to your healthcare provider or pharmacist.
