These factors may affect how you should use this medication.
Congestive heart failure: If you have moderate congestive heart failure, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. This medication should not be used for people with severe congestive heart failure. People with severe heart failure who take this medication have an increased chance of dying.

Kidney function: The results of a blood test for kidney function, called creatinine, may be increased without a change in your kidney function. Your doctor will use the creatinine level as your new normal. Tell any other doctor you see about the new “normal” value of your blood creatinine.
Liver: There have been reports of liver injury in people who were taking dronedarone. Your doctor may regularly perform tests to monitor your liver function. If you experience symptoms of liver damage (e.g., yellowing of the skin or eyes, fatigue, abdominal pain, nausea, vomiting, dark urine, or itching), contact your doctor immediately.

If they are low, your doctor may recommend that you take supplements or may make changes to your medications.
