digitoxin calcium acetate
Applies to: digitoxin, PhosLo (calcium acetate)
MONITOR: Excessive administration of calcium can aggravate digitalis toxicity and precipitate serious cardiac arrhythmias in digitalised patients. The mechanism probably involves additive or synergistic inotropic effects of calcium and digitalis glycosides on the myocardium.
MANAGEMENT: Caution is advised if calcium preparations are used in patients receiving digitalis glycosides. Patients should be advised not to exceed the calcium dosage prescribed for them and to consult their healthcare provider before consuming additional products that may contain substantial amounts of calcium (e.g., over-the-counter supplements).
