Micro-K is used to treat or prevent low potassium levels in people who may face potassium loss caused by digitalis (Lanoxin), non-potassium-sparing diuretics (such as Diuril and Dyazide), and certain diseases.

Potassium plays an essential role in the proper functioning of a wide range of systems in the body, including the kidneys, muscles, and nerves. As a result, a potassium deficiency may have a wide range of effects, including dry mouth, thirst, reduced urination, weakness, fatigue, drowsiness, low blood pressure, restlessness, muscle cramps, abnormal heart rate, nausea, and vomiting.

Micro-K and the other products discussed here are slow-release potassium formulations.
