What is EFFER-K?
(EFFER-K) 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.
How should I use EFFER-K?
Take this medication by mouth as directed by your doctor, usually 1 to 4 times daily. To prevent stomach upset, take each dose with a meal. Dissolve the prescribed number of tablets in at least 4 ounces (120 milliliters) of cold water or juice per tablet. After the tablets are fully dissolved, sip the liquid slowly over 5 to 10 minutes. If you have upset stomach, mixing your dose in a larger amount of liquid may help. 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 should I tell my health care provider before I take EFFER-K?
Before taking potassium, tell your doctor or pharmacist if you have any allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. Before using this medication, tell your doctor or pharmacist your medical history, especially of: heart problems, kidney problems, high levels of potassium in the blood, throat/stomach/intestinal problems (such as blockage, narrowing, ulcers). Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Before using other potassium supplements or salt substitutes that contain potassium, consult your doctor or pharmacist. Too much potassium may cause serious side effects. (See also Overdose section.) During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor. Potassium passes into breast milk. Consult your doctor before breast-feeding.
What may interact with EFFER-K?
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions.

Do not start, stop, or change the dosage of any medicines without your doctor's approval.

Examples include eplerenone, ACE inhibitors such as enalapril/lisinopril, angiotensin receptor blockers such as losartan/valsartan, potassium-sparing "water pills"/diuretics such as spironolactone/triamterene, birth control pills that contain drospirenone, among others.
