CRITICAL

Potassium-Enriched Salt Substitutes (NoSalt, Nu-Salt)

NLM MedlinePlus Dietary Warning & openFDA

Bioactive Compound:Potassium Chloride (KCl)

Biological Target:Renal Cortical Collecting Duct Electrophysiology

Clinical Mechanism:

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.

Patient Actionable Rule:Strictly avoid low-sodium seasonings containing potassium chloride without explicit physician approval and laboratory electrolyte monitoring.

Prescription & OTC Drug Interactions (DDI)

Documented pharmacological conflicts & contraindicated co-prescriptions

1 Warning Classes

HIGH RISK

NSAIDs (Ibuprofen, Naproxen) & Non-Cardioprotective Analgesics

openFDA SPL Section 7 (Drug Interactions)

Mechanism: Inhibition of renal vasodilatory prostaglandins (PGI2, PGE2) causes afferent arteriolar vasoconstriction, blunts blood pressure control, and increases risk of acute kidney injury (AKI).

Clinical Consequence: Loss of blood pressure reduction, fluid retention, or acute renal hemodynamic compromise.

Physician Precaution: Consult your physician before taking OTC pain relievers. Acetaminophen may be preferred for occasional pain depending on liver status.

Dietary Supplements, Herbs & Minerals (DNI)

Interactions with over-the-counter vitamins, minerals, and herbal preparations

2 Monitored

CRITICAL

Potassium Supplements (Potassium Chloride, Gluconate, Citrate)

NIH Office of Dietary Supplements (ODS) & NLM MedlinePlus

Biological Target: Myocardial Resting Membrane Potential & Cardiac Conduction

Direct renin inhibition suppresses downstream aldosterone secretion, preventing physiological urinary potassium excretion. Exogenous potassium supplements directly provoke dangerous serum hyperkalemia.

Guidance & Spacing:Do not take oral potassium supplements unless specifically prescribed and monitored by your physician.

HIGH

St. John's Wort (Hypericum perforatum)

NIH National Center for Complementary and Integrative Health (NCCIH)

Biological Target: Hepatic Cytochrome P450 3A4 / 2C9 & P-glycoprotein (P-gp)

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.

Guidance & Spacing:Completely avoid herbal St. John's Wort while taking prescription medications.
