2. What you need to know before taking Flecard

Do not take Flecard

• if you are allergic (hypersensitive) to flecainide or any of the other components of this medication (listed in section 6),
• if you have heart failure (insufficient blood pumping to the rest of the body), as flecainide may worsen it,
• if you have had a recent myocardial infarction (heart attack) or have had cardiogenic shock (acute heart failure), as flecainide may produce new arrhythmias or worsen existing ones,
• if you have rhythm disorders (a type of block or long-standing atrial fibrillation) or suffer from heart valve disease, as flecainide may produce new arrhythmias or worsen existing ones,
• if you have had cardiogenic shock (acute heart failure) in case of known hypersensitivity.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Flecard

• Flecainide may produce new arrhythmias or worsen existing ones.
• If you have heart failure, flecainide may worsen it.
• If you have a pacemaker, flecainide may interfere with its proper functioning.
• If you have renal or hepatic insufficiency (liver or kidney dysfunction), flecainide levels in the blood may increase because it is eliminated more slowly.
• If you have coronary artery disease, flecainide may slow down the heart rate or even cause cardiac arrest.
• If you have conduction disorders (a type of block), flecainide may increase the intensity of these blocks.
• If you have altered potassium levels, flecainide toxicity may increase.
• When flecainide is administered with antiarrhythmics, beta-blockers, tricyclic antidepressants, neuroleptics, the levels of both medications may increase.

Consult your doctor, even if the aforementioned circumstance has occurred to you at some point.

Taking Flecard with other medications

Tell your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication.

• Digoxin (medication to treat heart failure and abnormal heart rate, arrhythmias), as flecainide may increase its levels in the blood.
• Quinidine and amiodarone (antiarrhythmics), as they may increase flecainide levels in the blood.
• Propranolol and sotalol (antiarrhythmics), as they may decrease the heart's contractile force when taken with flecainide.
• It is not recommended to use flecainide with verapamil and diltiazem (antiarrhythmic medications).
• Some antidepressants, as they may increase flecainide levels in the blood and the risk of arrhythmias (fluoxetine, reboxetine, etc.).
• Phenytoin, phenobarbital, and carbamazepine (medications to treat epilepsy), as they increase flecainide elimination.
• Clozapine (a medication for schizophrenia), as it increases the risk of arrhythmias.
• Mizolastine and terfenadine (medications to treat allergies), as they increase the risk of heart rhythm disorders.
• Quinine (a medication for malaria), as it increases flecainide levels in the blood.
• Ritonavir, lopinavir, and indinavir (medications for AIDS treatment), as they increase flecainide levels in the blood.
• Diuretics, as they may alter potassium levels in the blood and increase flecainide toxicity.
• Cimetidine (an antacid), as it increases flecainide levels in the blood.
• Bupropion (a medication to help quit smoking), as it increases flecainide levels in the blood.

If you forget to take more than one dose, or your irregular and rapid heartbeat seems to have worsened, consult your doctor immediately.
