The generic form of Potassium Chloride ER (Potassium Chloride ER) contains the same active ingredient and is bioequivalent to the brand. Ask your pharmacist to dispense the generic — it works the same way, typically at a fraction of the brand-name cost.
Tip: In most states, pharmacists can substitute a generic unless your prescriber writes "dispense as written" (DAW).
Potassium Chloride ER (20mEq) is sold under the brand name Klor-Con and the generic Potassium Chloride ER. A standard supply tracked here is 30 units at 20mEq.
Pharmacy pricing is not regulated in the United States, so retailers set their own cash prices. Large retailers like Walmart and Costco typically offer lower prices on generics because they use prescriptions as a traffic driver. Chain pharmacies like CVS and Walgreens tend to charge more for the same medication.
Heart medications are typically maintenance therapy taken indefinitely, so comparing pharmacy prices can produce substantial long-term savings.
Potassium Chloride ER belongs to a class of medications called potassium supplements, prescribed to treat or prevent low potassium levels — often in patients taking certain diuretics that cause the body to lose potassium. The extended-release form is designed to release potassium gradually to reduce stomach irritation; it should be swallowed whole rather than crushed or chewed unless your prescriber or pharmacist says otherwise for your specific product. Potassium levels that run too high can also be dangerous, so dosing is managed by your prescriber based on lab monitoring, not adjusted on your own.
Shop around. The cheapest pharmacy tracked here (Costco at $6.08) charges meaningfully less than the most expensive option ($27.53). A quick call can save real money.
Ask for the generic. If your doctor prescribed the brand-name Klor-Con, ask your pharmacist whether a generic is available. In most states, pharmacists can substitute a generic unless the prescriber writes "dispense as written."
Use a discount card. Services like GoodRx, SingleCare, and WellRx can sometimes negotiate prices lower than retail cash. The estimated low price for Potassium Chloride ER is around $5.29.
Because Potassium Chloride ER is a generic medication, manufacturer-sponsored copay savings cards — the kind commonly offered for newer, brand-name drugs — generally aren't available for it. Klor-Con's manufacturer typically doesn't offer a savings card once generic competition exists, though it's worth checking their site directly if your prescriber specifically writes for the brand product. For most patients filling the generic, the discount-card and pharmacy membership options described above are the more realistic way to lower cost.
Coverage depends on your specific plan and formulary. Most medications in this category are covered under standard health insurance, typically in Tier 1 or Tier 2. If your copay is higher than the cash price above, it may be cheaper to pay out of pocket — ask your pharmacist to compare. Potassium supplements are typically inexpensive and are rarely subject to prior authorization.

What if my insurance doesn't cover Potassium Chloride ER at all?
Ask your prescriber whether a covered therapeutic alternative in the same drug class exists, or ask your pharmacist about a formulary exception or medical-necessity appeal — some plans will cover an otherwise-excluded drug once that documentation is on file. In the meantime, the cash and discount-card pricing shown above is usually the fastest fallback.
Does a 90-day supply of Potassium Chloride ER cost less than three 30-day fills?
Often, yes — many pharmacies and insurance plans price a 90-day fill at a lower effective per-dose cost than separate 30-day fills, and some mail-order pharmacy benefits are built specifically around 90-day supplies. Ask your pharmacist or insurer whether a 90-day option is available for this medication before assuming the count shown above is your only choice.
