What is potassium chloride ER and how does it work?
Potassium chloride ER is an oral mineral electrolyte supplement in the class of potassium replenishers. It is FDA-approved for the treatment and prevention (prophylaxis) of hypokalemia, or low blood potassium, with or without metabolic alkalosis, in patients for whom eating more potassium-rich foods or lowering a diuretic dose is not enough. Potassium is essential for normal heart rhythm, muscle contraction, and nerve signaling.
It is most often prescribed for people taking potassium-wasting diuretics such as loop or thiazide water pills, and to replace potassium lost through vomiting, diarrhea, or certain kidney and hormonal conditions. The extended-release design lets the potassium dissolve gradually rather than all at once. It comes in several brand names, including Klor-Con, Klor-Con M, Klor-Con Sprinkle, K-Dur, K-Tab, and Micro-K.
Cost of potassium chloride ER without insurance
Potassium chloride is available as an FDA-approved, substitutable generic, so it is one of the more affordable prescriptions on the market. That said, cash prices are not uniform: two pharmacies on the same street can charge very different amounts for the identical generic tablet, which is exactly why comparing before you fill matters.
Rx.com compares the cash price across more than 60,000 pharmacies and gives you a free coupon that often beats the standard shelf price, even if you have no insurance or a high deductible. There is no membership fee. Enter your ZIP code above to see today's price and print, text, or show the coupon at the counter.
Brands and related medications
Because a substitutable generic exists, most people can be dispensed generic potassium chloride ER in place of a brand and pay less for the same active ingredient. Brand-name versions that use potassium chloride include Klor-Con and Klor-Con M, K-Dur, and the Micro-K sprinkle capsules. All contain the same potassium chloride salt in different tablet or capsule forms.
Potassium chloride is frequently prescribed alongside diuretics that deplete potassium, such as furosemide (a loop diuretic). By contrast, potassium-sparing diuretics like spironolactone raise potassium, so they are generally not combined with a potassium supplement without careful monitoring. Always let your prescriber and pharmacist know every medication you take.
Safety and side effects
Swallow potassium chloride ER tablets whole with a full glass of water and food. Do not crush, chew, or suck the tablets, because solid oral potassium chloride can cause ulcers or narrowing (stenosis) of the digestive tract if a tablet lodges against the lining. Stop the medication and contact your doctor right away if you have severe vomiting, abdominal pain, bloating, or signs of GI bleeding. Common, milder side effects include nausea, vomiting, diarrhea, stomach discomfort, and gas.
The main serious risk is hyperkalemia, or dangerously high potassium, which can trigger irregular heart rhythms and even cardiac arrest and may cause no symptoms at all. For this reason your provider monitors your blood potassium and sometimes an ECG. Potassium chloride is high-risk or should be avoided with potassium-sparing diuretics (amiloride, triamterene, spironolactone, eplerenone), ACE inhibitors and ARBs, and in kidney impairment. If potassium is very low (below 2.5 mEq/L), IV potassium is used instead. This is general information, not medical advice, so follow your own prescriber's instructions.
