chew your tablets. If you feel your condition is not improving while taking your
medicine, tell your doctor.
Do not stop taking your medicine without consulting your doctor.
The usual starting dose is 200 mg three times a day for one week, the dose will then be
lowered to 200 mg twice a day for another week.
After this your doctor will reduce the dose of Amiodarone again, usually to 200 mg once
a day, until you are told otherwise.
In some cases, your doctor may then decide to either increase or lower the amount you
take each day. This will depend on how you react to the medicine.

check your blood pressure and thyroid function regularly.
