Potassium gluconate is a type of mineral supplement taken orally by some patients who have low blood potassium, or hypokalemia. This medication is offered over the counter but should not be taken apart from the advice of a medical professional.
Adequate potassium levels are necessary for the proper functioning of the kidneys and the heart, as well as nerves and muscles. Certain medical conditions can cause blood potassium levels to become depleted, including serious or prolonged diarrhea or vomiting and hyperaldosteronism, which is the overproduction of a steroid hormone in the adrenal glands. Symptoms of low potassium include muscle cramps, irregular heartbeat, fatigue and constipation.
