Interactions ⬆ ⬇

Drug-drug:

Use with thiazide diuretics, loop diuretics, piperacillin, or amphotericin B may ↑ risk of hypokalemia.
Hypokalemia may ↑ risk of digoxin toxicity.
May produce prolonged neuromuscular blockade following the use of nondepolarizing neuromuscular blocking agents.
Phenobarbital or rifampin may ↑ metabolism and ↓ effectiveness.

Drug-Food:

Large amounts of salt or sodium-containing foods may cause excessive sodium retention and potassium loss.

Patient/Family Teaching ⬆ ⬇

Instruct patient to take medication as directed. Take missed doses as soon as remembered but not just before next dose is due. Explain that lifelong therapy may be necessary and that abrupt discontinuation may lead to Addisonian crisis. Patient should keep an adequate supply available at all times. Discontinue gradually if needed.
Advise patient to follow dietary modification prescribed by health care professional. Instruct patient to follow a diet high in potassium (see Food Sources for Specific Nutrients). Amount of sodium allowed in diet varies with pathophysiology.
Instruct patient to inform health care professional if weight gain or edema, muscle weakness, cramps, nausea, anorexia, or dizziness occurs.
Rep: Advise females of reproductive potential to notify health care professional if pregnancy is planned or suspected, or if breastfeeding. Monitor newborns of patients taking fludrocortisone during pregnancy for hypoadrenalism.
Advise patient to carry identification at all times describing disease process and medication regimen.
