Treats heart rate problems.

Cordarone (Amiodarone) is an option to treat heart rate problems when other medicines don't work, but it can take a few weeks to work and there's a lot of serious side effects.

  • A strong diuretic (water pill) that works well to get rid of extra fluids in your body through urination.
  • Lowers your blood pressure and your risk of heart attack and stroke.
  • Works better than thiazide diuretics (like Hydrochlorothiazide) at removing harmful levels of certain electrolytes, such as potassium.
  • Okay to take if you have kidney problems.
  • An option for treating life-threatening heart rate problems when other medicines or procedures haven't worked.
  • Cordarone (Amiodarone) has been shown to lower the number of heart rate problems you can experience after certain types of heart surgeries.
  • Available as a generic version, so it should be affordable.
  • Makes you urinate very frequently.
  • Can cause low levels of important electrolytes, such as potassium.
  • Not a good choice if you have eye, liver, or lung problems.
