What is the most important information I should know about procainamide injection (Pronestyl)?
Procainamide is given in a hospital setting. Your heart rate, breathing, blood pressure and other vital signs will be watched closely while you are receiving procainamide.
You should not use this medication if you are allergic to procainamide, or if you have a serious heart condition such as "AV block" (unless you have a pacemaker), lupus, or a history of "Long QT syndrome."
If possible, before you receive procainamide, tell your doctor if you have congestive heart failure, circulation problems, a history of heart attack or stroke (including "mini-stroke"), a weak immune system, kidney or liver disease, myasthenia gravis, asthma, or if you are allergic to aspirin, sulfites, or any type of numbing medicine.
In an emergency situation it may not be possible before you are treated to tell your caregivers about your health conditions or if you are pregnant or breast feeding. Make sure any doctor caring for you afterward knows that you have received this medication.
Procainamide can lower blood cells that help your body fight infections. Tell your doctor 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, sores in your mouth and throat, or unusual weakness.
