Flecainide belongs to the class of medications known as antiarrhythmics. It is used to treat or prevent abnormal heart rhythms in certain conditions (e.g., paroxysmal supraventricular tachycardias, sustained ventricular tachycardia). It works by slowing down the rate of nerve impulses causing the heart to beat, and by making the heart less likely to respond to abnormal impulses.

Auro Flecainide may be available under multiple brand names and/or in several different forms. Any specific brand name of Auro Flecainide may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Auro Flecainide may not be used for all of the conditions discussed here.

Your doctor may have suggested Auro Flecainide for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking Auro Flecainide, speak to your doctor. Do not stop taking Auro Flecainide without consulting your doctor.

Do not give Auro Flecainide to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Auro Flecainide if their doctor has not prescribed it.

The usual recommended adult starting dose of flecainide is 50 mg to 100 mg twice daily, depending on the type of abnormal heart rhythm being treated. Usually, Auro Flecainide is taken every 8 to 12 hours. The dose and interval may be changed by your doctor according to your response to the medication. Flecainide can be taken with or without food. For some people, Auro Flecainide is started in the hospital, where heart rhythm can be closely monitored.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to take Auro Flecainide exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Auro Flecainide at room temperature, protect it from light and moisture, and keep it out of the reach of children.
