Why is this medication prescribed?
Procainamide is used to treat abnormal heart rhythms. It works by making your heart more resistant to abnormal activity.
How should this medicine be used?
Procainamide comes as a capsule and tablet to take by mouth. Immediate-acting procainamide usually is taken every 3 or 4 hours. The long-acting product is usually taken every 6 or 12 hours. Do not cut, crush, or chew extended-release (long-acting) tablets; swallow them whole. You may see a waxy core in your stool if you are taking the extended-release product; this is normal.
Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take procainamide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Procainamide helps control your condition but will not cure it. Continue to take procainamide even if you feel well. Do not stop taking procainamide without talking to your doctor.
Other uses for this medicine
This medication should not be prescribed for other uses; ask your doctor or pharmacist for more information.

What other information should I know?
Keep all appointments with your doctor and the laboratory. Your doctor will need to determine your response to procainamide.
Take procainamide at the same time each day in regularly spaced intervals. Changing the time of your doses prevents procainamide from working effectively.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
