Digoxin
Comprehensive clinical interaction and dietary monograph for Digoxin (Digoxin).
Kitchen Food, Drink & Dietary Conflicts
Biochemical interactions with common foods, beverages & cooking ingredientsYour doctor may recommend a low-sodium (low-salt) diet and a potassium supplement. Ask your pharmacist or doctor for a list of foods that are low in sodium and high in potassium. Follow all diet directions carefully.
Grapefruit / Pomelo (Citrus paradisi / Citrus maxima)
Destroys enterocyte CYP3A4 enzymes, collapsing first-pass drug metabolism and causing up to 12-fold spikes in bioavailability for oral CYP3A4 substrates (statins, calcium channel blockers, immunosuppressants, PDE5 inhibitors).
Natural Black Licorice & Licorice Root Extracts
Inhibits cortisol breakdown into cortisone in the kidney. Cortisol saturates mineralocorticoid receptors, causing massive renal sodium retention, severe potassium wasting, edema, and dangerous spikes in blood pressure that neutralize antihypertensives.
Alcoholic Beverages (Beer, Wine, Spirits)
Multiplies respiratory depression and profound sedation with opioids and sedatives; blocks hepatic lactate uptake with metformin (lactic acidosis); triggers acute disulfiram-like vomiting and tachycardia with metronidazole; and accelerates dose-dumping in extended-release capsules.
Potassium-Enriched Salt Substitutes (NoSalt, Nu-Salt)
Exogenous potassium chloride loads cannot be cleared efficiently when RAAS or renal filtration is modified, risking acute lethal hyperkalemia (>6.5 mEq/L) and ventricular arrhythmias.
Prescription & OTC Drug Interactions (DDI)
Documented pharmacological conflicts & contraindicated co-prescriptionsDietary Supplements, Herbs & Minerals (DNI)
Interactions with over-the-counter vitamins, minerals, and herbal preparationsPotassium Supplements (Potassium Chloride, Gluconate, Citrate)
Direct renin inhibition suppresses downstream aldosterone secretion, preventing physiological urinary potassium excretion. Exogenous potassium supplements directly provoke dangerous serum hyperkalemia.
St. John's Wort (Hypericum perforatum)
Hyperforin potently activates the Pregnane X Receptor (PXR), inducing hepatic CYP enzymes and intestinal P-gp pumps. This accelerates medication clearance and precipitates therapeutic failure.
