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.

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.

To be sure this medication is helping your condition, your blood may need to be tested often. Your heart rate may also be checked using an electrocardiograph or ECG (sometimes called an EKG) to measure electrical activity of the heart. This test will help your doctor determine how long to treat you with potassium. Do not miss any scheduled appointments.
Serious side effects of potassium include uneven heartbeat, muscle weakness or limp feeling, severe stomach pain, and numbness or tingling in your hands, feet, or mouth.
Do not stop taking this medication without first talking to your doctor. If you stop taking potassium suddenly, your condition may become worse.
