What Is Potassium?
Potassium chloride (potassium) is a prescription medication used to manage hypokalemia, a condition in which blood potassium levels fall below the normal range. It works by directly replenishing potassium, an essential electrolyte that regulates muscle contraction, nerve signaling, and heart rhythm. With the right dose and ongoing monitoring, most patients are able to restore and maintain healthy potassium levels safely.

Is Online Potassium Treatment Right for You?
Doctronic can evaluate patients who have been diagnosed with hypokalemia or who show signs of low potassium, such as muscle weakness, cramping, or irregular heartbeat, and determine whether prescription potassium chloride is appropriate. A physician will review your lab values and medical history before prescribing.
Because potassium balance is closely tied to kidney function, heart health, and certain medications such as diuretics, your provider will ask about your cardiovascular and renal history to ensure potassium supplementation is safe for you.

Medications We Prescribe for Hypokalemia
Klor-Con
Potassium Chloride ER
The most commonly prescribed oral potassium supplement, available in extended-release tablets for convenient once- or twice-daily dosing.
AvailableK-Dur
Potassium Chloride ER
An extended-release potassium chloride formulation used to treat and prevent low potassium, often prescribed when dietary intake alone is not sufficient.
AvailableMidamor
Amiloride
A potassium-sparing diuretic that helps prevent potassium loss through the kidneys, sometimes used alongside potassium replacement therapy.
AvailableMagnesium
Magnesium
Hypomagnesemia frequently co-exists with hypokalemia and can make potassium replacement less effective; correcting magnesium levels often supports potassium repletion.

Frequently asked questions
Hypokalemia means your blood potassium level is below 3.5 milliequivalents per liter. Common causes include the use of diuretics (water pills), prolonged vomiting or diarrhea, inadequate dietary intake, certain kidney conditions, and medications such as corticosteroids or amphotericin B.
Over-the-counter supplements are limited by law to 99 mg of potassium per tablet, which is a fraction of a typical therapeutic dose. Prescription potassium chloride, such as Klor-Con or K-Dur, delivers higher doses in extended-release formulations designed to safely and effectively correct a clinically low potassium level.
Common symptoms of low potassium include muscle weakness, cramps, or aches, fatigue, constipation, palpitations or an irregular heartbeat, and tingling or numbness. Severe hypokalemia can cause paralysis or dangerous heart arrhythmias and requires prompt medical attention.
Yes. Foods rich in potassium include bananas, oranges, potatoes, sweet potatoes, avocados, spinach, beans, and dairy products. However, dietary changes alone are usually not enough to correct clinically low potassium, and prescription supplementation is typically required.
Your provider will typically recommend periodic blood tests to check serum potassium and kidney function. Potassium levels that are too high (hyperkalemia) can be just as dangerous as levels that are too low, so regular lab monitoring is an important part of safe treatment.
Yes. Potassium chloride can interact with potassium-sparing diuretics (such as spironolactone or amiloride), ACE inhibitors, ARBs, and certain heart medications. High potassium combined with these drugs can raise the risk of hyperkalemia. Always share your full medication list with your provider.
