From the FDA Drug Label

DOSAGE AND ADMINISTRATION ... Doses of 40 mEq to 100 mEq per day or more are used for the treatment of potassium depletion.

Dosage should be divided if more than 20 mEq per day is given such that no more than 20 mEq is given in a single dose.

The maximum oral potassium dose is not explicitly stated, but the label indicates that doses up to 100 mEq per day or more are used for treatment of potassium depletion, with a single dose limit of 20 mEq 1.
