Podcast # 336: Hypokalemia

Author: Dylan Luyten, MD

Educational Pearls:

  • Most important questions to answer with low potassium are 1. What are their symptoms? 2. Can they take potassium by mouth?
  • Oral repletion is faster, cheaper, and more effective than IV repletion.
  • Give IV potassium when patients have K < 2.5 mmol/L or present with arrhythmias and/or characteristic EKG changes (flattened T waves).
  • Most patients who are hypokalemic are hypomagnesemic and require magnesium supplementation. Checking a level is unnecessary.
