What is potassium gluconate?

Potassium is a mineral that is found in many foods and is needed for several functions of your body, especially the beating of your heart.

Potassium gluconate is used to prevent or to treat low blood levels of potassium (hypokalemia). Potassium levels can be low as a result of a disease or from taking certain medicines, or after a prolonged illness with diarrhea or vomiting.

Potassium gluconate may also be used for other purposes other than those listed in this medication guide.

What should I discuss with my healthcare provider before taking potassium gluconate?

You should not use this medication if you are allergic to it, or if you have certain conditions. Be sure your doctor knows if you have:

  • kidney failure;
  • Addison's disease (an adrenal gland disorder);
  • a large tissue injury such as a severe burn;
  • if you are severely dehydrated; or
  • if you are taking a "potassium-sparing" diuretic (water pill) such as amiloride (Midamor, Moduretic), spironolactone (Aldactone, Aldactazide), triamterene (Dyrenium, Dyazide, Maxzide).

You should not take potassium gluconate tablets if you have problems with your esophagus, stomach, or intestines that make it difficult for you to swallow or digest pills.
