1.    What Amiodarone is and what it is used for

Your tablet contains amiodarone hydrochloride, which belongs to a class of medicines known as antiarrhythmics.

It works by controlling the uneven beating of your heart (called ‘arrhythmias’). Taking the tablets helps your heartbeat to return to normal.

Amiodarone can be used to:

•    Treat uneven heartbeats where other medicines either have not worked or cannot be used.

•    Treat an illness called Wolff-Parkinson-White Syndrome. This is where your heart beats unusually fast.

•    Treat other types of fast or uneven heartbeats known as ‘atrial flutter’ or ‘atrial fibrillation. Amiodarone is used only when other medicines cannot be used.

•    Treat fast heartbeats which may happen suddenly and may be uneven. Amiodarone is used only when other medicines cannot be used.

2.    What you need to know before you take Amiodarone Do not take Amiodarone if:

•    you are allergic to amiodarone or to any of the other ingredients of this medicine (listed in section 6) or to iodone. Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue.

•    you have a slower than usual heartbeat (called ‘sinus bradycardia’) or an illness called ‘sino-atrial’ heart block.

•    you have any other problems with your heartbeat and do not have a pacemaker fitted.

•    you have or have had thyroid problems. Your doctor should test your thyroid before giving you this medicine.

The doctor may give you a lower dose of Amiodarone Tablets. Also, the doctor should check your blood pressure and thyroid function regularly.
