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.
Take this medication by mouth as directed by your doctor. To prevent stomach upset, take each dose with a meal and a full glass of water (8 ounces/240 milliliters) unless your doctor directs you otherwise. Do not lie down for 10 minutes after taking this medication.
Do not crush, chew, or suck on the tablets. Doing so can release all of the drug at once, increasing the risk of side effects.
If you have trouble swallowing the tablets, you may break the tablet in half and take one half with a glass of water; then take the other half tablet with another glass of water. Another choice is to dissolve the tablet in a half glass of water (4 ounces/120 milliliters) before taking it. After the tablet dissolves (about 2 minutes), stir the mixture for 30 seconds then drink all the liquid. Add one more ounce (30 milliliters) of water to the glass, swirl, and drink. Repeat one more time to make sure you are getting all of the drug. Use only water for mixing, and do not prepare the mixture ahead of time. Ask your doctor or pharmacist if you have any questions.
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. Do not take more than 20 milliequivalents per dose.
Tell your doctor right away if you have any serious side effects, including: difficult/painful swallowing, feeling as if the tablet is stuck in your throat.
Get medical help right away if you have any very serious side effects, including: vomit that looks like coffee grounds, stomach/abdominal pain, black/tarry stools.
