Hypokalemia is defined as a serum potassium level less than 3.5 mmol/L (3.5 mEq/L); hypokalemia at levels between 3.1 and 3.4 mmol/L is considered mild. The incidence of hypokalemia reported for patients on diuretic therapy is broad (7.2% to 56%), 3 - 6 and the time period required to develop hypokalemia varies (1 week6 to >1 year 7 ). Factors including the type of diuretic used, dosage, duration of use, dietary potassium, and so forth, make predicting an individual patient’s progression nearly impossible. Widmer and coworkers5 found that the risk of hypokalemia was greatest with concomitant glucocorticoid use, polypharmacy (greater than 12 medications administered), and female sex. The latter risk factor may be related to a higher dose-to-weight relationship.
