Pronestyl injection

Procainamide is injected into a muscle or into a vein through an IV. You will receive procainamide injection in a hospital setting where your heart can be monitored in case the medication causes serious side effects.

Your heart rate will be constantly monitored using an electrocardiograph or ECG (sometimes called an EKG). This machine measures electrical activity of the heart. Your breathing, blood pressure and other vital signs will be watched closely while you are receiving procainamide.

Procainamide can lower blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. Contact your doctor at once if you develop signs of infection such as fever, chills, sore throat, flu symptoms, easy bruising or bleeding (nosebleeds, bleeding gums), loss of appetite, nausea and vomiting, mouth sores, or unusual weakness.

Your doctor will need to check your progress on a regular basis. Do not miss any scheduled appointments.

Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

Overdose symptoms may include drowsiness, tremors, weak or shallow breathing, and fainting.

Avoid being near people who have colds, the flu, or other contagious illnesses. Contact your doctor at once if you develop signs of infection.

This medication may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
