Tambocor (flecainide) is an antiarrhythmic agent, used to prevent or treat certain cardiac arrhythmias (irregular heartbeats).

Cardiac arrhythmias are a complicated subject. There are many types, and not all types are best treated with Tambocor. A doctor will need to diagnose the exact arrhythmia and prescribe Tambocor.

The medication works by slowing nerve impulses in the heart through regulating the flow of sodium in heart tissue. It is often used to treat:

• AV nodal re-entrant tachycardia
• Wolff-Parkinson-White syndrome
• Right ventricular outflow tract tachycardia
• Arrhythmogenic right ventricular dysplasia
• Ventricular tachycardia
• Paroxysmal supraventricular tachycardia
• Atrial fibrillation

Tambocor may be used to treat other arrhythmias not listed above; the above are simply common uses.

This product can be used in children, though dosage modifications are needed. A doctor can best determine if Tambocor is suitable and at what dose.

All patients taking Tambocor are advised to carry identification stating that the medication is being taken so that, in case of emergency, doctors are aware.

Maintaining a Healthy Heartbeat

Tambocor comes in tablets, either 50 mg or 100 mg doses. Tablets are typically taken twice per day, with or without food.

The first dose of Tambocor is often given in a hospital or other medical setting where the patient's heart can be monitored. This helps doctors determine the medication works, at what dosage, and to see if serious side effects develop.

It is not possible to summarize treatment, as it's highly individualized according to patient response and numerous personal factors. We can summarize some general rules, but keep in mind that even these may change:

• Most patients start on 50 to 100 mg, taken every 12 hours (twice per day).
• Some patients take a dose every 8 hours (three times per day).
• Dosage increases are usually done in 50 mg increments.
• Many patients find 150 to 200 mg per day to be sufficient.
• Patients should not exceed 400 mg total per day.
• Patients with severe renal disease should not exceed 100 mg per day.
• Patients with moderate renal disease should not exceed 200 mg per day.

Effects are noticeable with the first dose. If a dose is missed, it should be taken as soon as remembered unless it's within 6 hours of the next dose, in which case it should be skipped.

If relatively mild but disruptive side effects are encountered on twice-per-day dosing, changing to three-times-per-day dosing may help alleviate them. Be sure to check with a doctor before doing so.

Be sure to keep all doctor's appointments. Doctors will want to monitor the condition and to make sure the medication is working as intended. Regular checkups will also allow doctors to screen for developing side effects.

Note that this medication can cause serious, even fatal, heart complications if used in the wrong condition. Do not use Tambocor without doctor approval. In patients who have an otherwise healthy heart, Tambocor is widely regarded as safe.

Precautions & Side Effects

Other medications can influence Tambocor dosage, sometimes quite significantly. Other antiarrhythmia agents are a concern, as are diuretics and other blood pressure medications, but many other, unrelated medications can also interact with Tambocor. Double-check with a doctor or pharmacist before using multiple medications.

Other medical conditions can also influence Tambocor treatment. Make sure the doctor knows if there is any history of:

• Liver disease
• Kidney disease
• Heart disease
• Heart attack
• Congestive heart failure

Additionally the doctor will need to be aware if a pacemaker has been implemented.

Patients taking Tambocor should alert their doctor right away if the condition worsens. Other serious side effects, which warrant medical attention, include:

• Chest pain
• Severe dizziness
• Fainting
• Fever or chills
• Difficulty breathing
• Tremors
• Jaundice
• Swelling in hands, feet, or lower legs

Women who are pregnant or breastfeeding should discuss using Tambocor with a doctor.
