1. What Tambocor is and what it is used for

Tambocor tablets belong to a group of medicines called anti-arrhythmics. Anti-arrhythmics work by controlling the rate and rhythm of the heart.

Tambocor tablets are used to treat:

•    Arrhythmias (irregular heart beat)

•    Tachycardia (heart beat too fast)

•    Atrial fibrillation (rapid contractions of muscles in the heart).

It is important for your doctor to treat these conditions quickly and effectively in order to prevent more serious heart problems from developing.

There are two strengths of tablet available, 50 mg and 100 mg.

2. What you need to know before you take Tambocor tablets

Do not take Tambocor tablets if:

•    You are allergic to flecainide acetate or any of the other ingredients of Tambocor tablets (see Section 6)

•    You have heart block (your heart misses beats)

•    You have long-standing atrial fibrillation (rapid contractions of muscles in the heart)

•    You have sinus node dysfunction (a specific condition where your heart beats abnormally)

•    You have had a myocardial infarction (heart attack)

•    You have Brugada Syndrome, a genetic disease that causes severe disturbances of the rhythm of the heart and may lead to sudden death in apparently healthy individuals.

•    You are pregnant or breast-feeding.

Tambocor tablets are not recommended for use in children under 12 years of age, however, dairy products such as milk, infant formula and possibly yoghurt, may reduce how much Tambocor is absorbed in children and infants.
