Medical Editor: John P. Cunha, DO, FACOEP
K-Tab (potassium chloride) Extended-Release Tablets is a form of the mineral potassium 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. Common side effects of K-Tab include stomach pain or upset, nausea, vomiting, diarrhea, tingling in your hands or feet, or the appearance of a potassium chloride tablet in your stool.
Dosage of K-Tab is adjusted to the needs of each patient. The usual dose for the prevention of hypokalemia is 20 mEq per day. Doses of 40-100 mEq per day or more are used for the treatment of potassium depletion. K-Tab may interact with eplerenone, digoxin, quinidine, bronchodilators, ACE inhibitors, or diuretics. Tell your doctor all medications and supplements you use. During pregnancy, K-Tab should be used only if prescribed. This drug passes into breast milk. Consult your doctor before breastfeeding.
