Potassium chloride is a low-cost generic potassium supplement sold under brand names like Klor-Con, Klor-Con M, K-Tab, K-Dur, and Micro-K, and prescribed to prevent or treat low blood potassium (hypokalemia). Because it is already generic, cash prices are usually modest, but they still vary a lot from one pharmacy to the next, so it pays to compare.

What is potassium chloride and how does it work?

Potassium chloride is a mineral and electrolyte supplement (a potassium salt). It replaces potassium your body has lost, restoring normal blood levels so your nerves, muscles, and heart can work properly. Doctors most often prescribe it to prevent or treat hypokalemia (low blood potassium), with or without metabolic alkalosis, including in people taking diuretics ("water pills") or digitalis, and in those with hypokalemic familial periodic paralysis.

It comes in several oral forms: extended-release tablets and capsules, powder or granules to mix into a solution, effervescent tablets, and an oral liquid. Extended-release solid forms are generally reserved for people who cannot tolerate liquid or effervescent preparations. (A separate potassium chloride injection is used in hospitals for more severe deficiency.)

Potassium chloride cost and coupons without insurance

Potassium chloride is available as an FDA-approved generic, so it is typically one of the more affordable prescriptions even if you pay cash. There is no manufacturer copay savings card for this generic. The catch is that pharmacy cash prices are not standardized, and the same prescription can cost noticeably more at one store than at another down the street, which is exactly why comparing before you fill matters.

Rx.com compares prices across more than 60,000 pharmacies and shows a free discount you can use whether or not you have insurance. Enter your ZIP above to see today's price near you and print, text, or show the coupon at the pharmacy counter. The discount applies to the generic as well as the brand versions such as Klor-Con and K-Tab.

Related medications and alternatives

Potassium chloride is often prescribed alongside a diuretic, because some "water pills" cause the body to lose potassium. These include furosemide, hydrochlorothiazide, and chlorthalidone — potassium chloride helps replace what they deplete.

Not every diuretic lowers potassium. Spironolactone is a potassium-sparing diuretic, meaning it tends to raise potassium, so it should generally not be combined with a potassium supplement without close monitoring. Only your prescriber can decide which combination is right for you and what dose of potassium, if any, you need. Never start or stop a potassium supplement on your own.

Important safety information

Solid oral controlled- and extended-release potassium chloride tablets carry a strong warning about the digestive tract: if a tablet lingers against the lining, it can cause ulceration, bleeding, and narrowing or blockage of the GI tract. To lower this risk, take it with meals and a full glass of liquid, and never crush, chew, or suck the tablets — swallow them whole. Extended-release forms are reserved for patients who cannot tolerate liquid or effervescent preparations.

Potassium chloride should not be used by people who already have high blood potassium (hyperkalemia). It should be used with caution, or avoided, with potassium-sparing diuretics, ACE inhibitors, ARBs, or aldosterone blockers, which all raise the risk of dangerously high potassium. Hyperkalemia can cause muscle weakness, tingling, irregular heartbeat, and even cardiac arrest. People with kidney problems need extra caution, and blood potassium is monitored during treatment. This is general information, not medical advice — talk with your doctor or pharmacist about your specific situation.
