• If you are allergic to flecainide or any of the other components of this medication (listed in section 6).
• If you have heart failure, as it may worsen with flecainide.
• If you have had a recent myocardial infarction, as flecainide may produce new arrhythmias or worsen existing ones.
• If you have rhythm disturbances (a type of block or have had atrial fibrillation for a long time) or have heart valve disease, as flecainide may produce new arrhythmias or worsen existing ones.
• If you have had a cardiogenic shock or in case of known hypersensitivity.
• Known Brugada syndrome.
• If you have sinoatrial dysfunction, atrioventricular conduction defects, second-degree or higher atrioventricular block, branch block, or distal block.

Warnings and precautions

Consult your doctor or pharmacist before starting to take this medication:

• As flecainide may produce new arrhythmias or worsen existing ones.
• If you have heart failure, as flecainide may worsen it.
• If you are wearing a pacemaker, as flecainide may interfere with its proper functioning.
• If you have renal or hepatic insufficiency, as it may increase flecainide levels in the blood, as it is eliminated more slowly.
• If you have coronary sinus disease, as flecainide may slow down heart rate or even cause cardiac arrest.
• If you have cardiac conduction disorders (a type of block), flecainide may increase the intensity of these blocks.
• If you have altered potassium levels, as flecainide toxicity may increase.
• When flecainide is administered with antiarrhythmics, beta-blockers, tricyclic antidepressants, neuroleptics, the levels of both medications may increase.
• In case of presenting ECG alterations that may suspect a Brugada syndrome
• Dairy products (milk, infant formulas, and some yogurts) may reduce flecainide absorption
• Flecainide, as a narrow therapeutic margin medication, requires caution and close monitoring when patients change to a different formulation.

Pediatric population

Flecainide is not recommended for use in children under 12 years old.

Geriatric patients:

In these patients, the elimination rate may be reduced, so this should be taken into account when making dose adjustments.

Taking Apocard with other medications

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

• Digoxin (a medication for treating heart failure and abnormal heart rate, arrhythmias), as flecainide may increase its levels in the blood.
• Quinidina and amiodarona (some antiarrhythmics), as they may increase flecainide levels in the blood.
• Propanolol and sotalol (some antiarrhythmics), as when taken with flecainide, they may decrease heart contraction force.
• Flecainide should not be used with verapamilo and diltiazem (some antiarrhythmics).
• Some antidepressants, as they may increase flecainide levels in the blood. The use of antidepressants (fluoxetina, paroxetina, reboxetina, etc) increases the risk of arrhythmias.
• Fenitoína, fenobarbital, and carbamazepina (some medications for treating epilepsy), as they increase flecainide elimination.
• Clozapina (a medication for schizophrenia), as it increases the risk of arrhythmias.
• Mizolastina and terfenadina (some medications for treating allergies), as they increase the risk of cardiac rhythm disturbances.
• Quinina (a medication for malaria), as it increases flecainide levels in the blood.
• Ritonavir (a medication for treating HIV/AIDS), as it increases flecainide levels in the blood.
• Cimetidina (an antacid), as it increases flecainide levels in the blood.
• Bupropión (a medication for helping to quit smoking), as it increases flecainide levels in the blood.
• Terbinafina (a medication for treating fungal infections), may increase flecainide levels in the blood.

Interference with diagnostic tests

Pregnancy, lactation, and fertility

Pregnancy

If you are pregnant or breastfeeding, or think you may be pregnant, consult your doctor or pharmacist before using this medication. Flecainide should only be used during pregnancy if the benefits outweigh the risks.

Lactation

Flecainide is excreted in breast milk. Although the risk of adverse effects in the infant is very low, this medication should only be used during breastfeeding if the benefits outweigh the risks.

During treatment, you may experience adverse effects (dizziness, and visual disturbances), so if you notice these symptoms, you should not drive or operate hazardous machinery.

Apocard contains sodium

This medication contains less than 1 mmol of sodium (23 mg) per tablet; it is essentially "sodium-free".

The recommended dose is one tablet twice a day.

Your doctor may recommend a maximum total dose of 400 mg (4 tablets) per day depending on your individual characteristics.

In elderly patients or in patients with severe liver and kidney failure, your doctor may monitor your flecainide blood levels.

Dosage in renal insufficiency: the initial maximum dose will not exceed 100 mg per day.

If you estimate that the action of Apocard is too strong or too weak, inform your doctor immediately.

Use in children

Currently, there are limited data available for children, and therefore the use of Apocard should be supervised by a cardiologist experienced in managing arrhythmias in pediatric populations.

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