In this session, we will be discussing the consumer medication information for amiodarone, trade name CordaroneTM, and PaceroneTM
What it’s for & How to take
Amiodarone is used to treat patients with an abnormal heartbeat. When your heart has an abnormal beat, you are more likely to develop a blood clot. Blood clots get stuck in your legs, lungs, heart or brain which may lead to a life-threatening emergency.
Amiodarone may slow down how fast and how strong your heart may beat. By doing this, the abnormal heart beat is decreased. This category of medications help keep a heartbeat regular and steady.
Amiodarone is usually taken 1 or 2 times daily. This medication may be taken with or without food, but try to take it the same way each time. Take your dose at the same time each day to get the best results.
Your doctor may start you on a higher dose, and then slowly decrease your dose after your heartbeat is normal.
Do not stop taking this medication or change the dose without talking with your doctor. If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.
