This medication is a mineral supplement used to treat or prevent low amounts of potassium in the blood. A normal level of potassium in the blood is important.

Potassium helps your cells, kidneys, heart, muscles, and nerves work properly.

Most people get enough potassium by eating a well-balanced diet. Some conditions that can lower your body’s potassium level include severe prolonged diarrhea and vomiting, hormone problems such as hyperaldosteronism, or treatment with “water pills”/diuretics.

Use and Dosage

To prevent stomach upset, you must first mix your dose of potassium with a glass (4 to 8 ounces/120 to 240 milliliters) of cold water or juice as directed by your doctor. If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. After mixing, slowly drink the entire mixture. Take each dose after a meal. If you have an upset stomach, mixing your dose in a larger amount of liquid may help. If you have any questions, ask your doctor or pharmacist.

Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day. The dosage is based on your medical condition and response to treatment. Do not increase your dose or take it more often than prescribed.

Tell your doctor if your condition does not improve or if you have symptoms of low potassium in the blood (such as irregular heartbeat, muscle weakness/cramps).

What happens if I overdose?

What to avoid?
