Though potassium chloride tablets are inexpensive and a logical choice of treatment (since chloride and potassium deficiencies are likely to co-exist), experimental and circumstantial evidence suggests these tablets may cause small-bowel ulcerations.1,2 Hence, the pharmaceutical industry has in recent years introduced a number of liquid potassium preparations.

One teaspoonful in 6 oz of fruit juice taken three times daily provides 40 mEq potassium chloride plus another 15 to 30 mEq of potassium depending on the type of fruit juice used. (Apple juice contains approximately 5 mEq potassium per 6-oz glass, tomato juice
