II. Causes: Medications Causing Hyperkalemia
- Drugs that increase Potassium release from cells
- Digoxin (esp. Digoxin Poisoning)
- Succinylcholine
- Aminocaproic acid
- Cyclosporine
- Tacrolimus
- Altered transmembrane Potassium shift
- Drugs that decrease renal Potassium excretion
- Potassium sparing Diuretics
- Potassium-Sparing Diuretic and Aldosterone Antagonists
- Agents that reduce Aldosterone secretion
- ACE Inhibitors
- Angiotensin Receptor Blockers (ARB)
- Yasmin (Spironolactone-like effect)
- NSAIDs
- Trimethoprim
- Blocks collecting tubule Sodium channel
- Do not combine with ACE Inhibitors, Angiotensin Receptor Blockers, Spironolactone
- Higher risk with age >65 years, Renal Insufficiency, Diabetes Mellitus and Heart Failure
- Fralick (2014) BMJ 349:g6196 +PMID:25359996 [PubMed]
- Other decreased renal excretion
- Other agents
- Antifungals (Ketoconazole, Fluconazole, Itraconazole)
- Fluorosis
- Hypertonic Infusions (Mannitol, Glucose)
- Penicillin G (high dose)
- Transfusions of pRBC
III. Causes: Herbal supplements that may increase Potassium
- Alfalfa
- Amino Acids (Aminocaproic acid, Arginine, Lysine)
- Dandelion
- Dried toad skin
- Hawthorne Berry
- Horsetail
- Liliy of the Valley
- Milkweed
- Nettle
- Noni Juice
- Siberian Ginseng
IV. Causes: Excessive Potassium intake
- See Potassium Supplementation
- Salt Substitute (e.g. Mrs. DASH)
- Fruits (Bananas, melons, orange juice)
