What is the most important information I should know about flecainide (Tambocor)?
You should not use this medication if you are allergic to flecainide, or if you have certain heart conditions, especially "AV block" (unless you have a pacemaker).
Before using flecainide, tell your doctor if you have congestive heart failure, a heart condition called "sick sinus syndrome," an electrolyte imbalance, liver disease, kidney disease, if you have a pacemaker, or if you have had a heart attack within the past 2 years.
You will need to receive your first few doses of flecainide in a hospital setting 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.
Call your doctor at once if you have a serious side effect such as weak pulse, slow breathing, fast or uneven heartbeat, feeling like you might pass out, feeling short of breath, swelling, rapid weight gain, confusion, extreme thirst, increased urination, muscle weakness, or jaundice (yellowing of the skin or eyes).
