FDA issues urgent recall for mislabeled potassium chloride injections

  • A voluntary recall is in effect for one lot of Potassium Chloride Injection, 20 mEq, from Otsuka ICU Medical LLC because the outer packaging incorrectly labels it as a 10 mEq dose.
  • If administered based on the wrong outer label, patients could receive a fatal overdose of potassium, which is the same substance used in lethal injections to stop the heart.
  • The error is particularly dangerous for vulnerable populations, including infants, those with heart or kidney conditions, and patients on specific diuretics.
  • The company claims no adverse events have been reported, but the product was distributed for months across the United States before the recall was initiated.
  • This incident forces a closer look at the dual nature of potassium, an essential mineral for health that becomes a potent poison when dosage is miscalculated.

The anatomy of a catastrophic error

The recalled product, Potassium Chloride Injection from Otsuka ICU Medical LLC, is a lifeline for millions suffering from hypokalemia, or low potassium. This condition affects an estimated 30 million Americans and can lead to serious muscle weakness and heart rhythm problems. In a clinical setting, when a patient cannot take oral supplements, this clear liquid is administered intravenously to correct the deficiency and restore vital functions. Yet, a single lot of this medicine was sent out into the world wearing a disguise. The outer wrap, the first thing a busy healthcare worker would see, falsely proclaimed the bag contained a 10 mEq dose. The truth—a 20 mEq concentration—was hidden on a label affixed directly to the bag inside. This is a critical failure point in the safety chain, a betrayal of the trust placed in pharmaceutical manufacturers to ensure absolute accuracy with powerful chemicals. What happens when this mislabeled poison enters the human body? The condition is called hyperkalemia, a dangerous elevation of potassium in the blood. The heart, a finely tuned muscle reliant on precise electrical impulses, is thrown into chaos. The result can be neuromuscular dysfunction, descending from mere weakness into full paralysis, mental confusion, a dangerous drop in blood pressure, and ultimately, cardiac arrhythmias or cardiac arrest. It is a grim, terrifying way to die, and it is the exact mechanism employed by the state in carrying out executions via lethal injection. The same chemical that restores life in a careful, measured dose can extinguish it in a reckless, unmeasured one.

Who is most at risk?

While any patient receiving the mislabeled infusion is in danger, the company’s own announcement highlights the populations for whom this error is a virtual death sentence. Premature infants, with their tiny, underdeveloped systems, cannot process such a toxic overload. Patients with chronic renal insufficiency or acute renal failure have kidneys that are already struggling to regulate potassium; a double dose can overwhelm them instantly. Those with a history of cardiac arrhythmias are playing with fire, as their hearts are already unstable. The recall notice reads like a checklist of the most vulnerable people in a hospital, those who come seeking care and are instead handed a hidden, iatrogenic death sentence. Where is the protection for these individuals? The system designed to safeguard them has instead placed them directly in the crosshairs. This incident forces a necessary and uncomfortable public conversation about the minerals we consume and the fine line between nutrient and toxin. For decades, extensive research has explored the relationship between dietary potassium and blood pressure. Meta-analyses of clinical trials, such as those published in JAMA and the Cochrane Database of Systematic Reviews, have consistently shown that oral potassium supplementation can have a modest, beneficial effect on lowering blood pressure. It is a vital nutrient that promotes vascular health. But the body demands balance. The research reveals that the benefits are dependent on correct dosage and individual patient status. The same scientific literature that praises potassium's hypertensive benefits also understands its deadly potential when concentration soars beyond the narrow window of safety. The recall is a stark, real-world lesson in this delicate biochemical balancing act. The affected lot was manufactured in April 2025 and distributed across the United States from late May through late August. The voluntary recall was not announced until the end of October. For months, this mislabeled, potentially lethal product sat on shelves in clinics and hospitals, ready to be administered. The company states it has received no reports of adverse events, but can we trust that silence? How many unexplained cardiac arrests or sudden patient downturns were not traced back to a simple labeling error on an IV bag? Sources include: Dailymail.co.uk FDA.gov Enoch, Brighteon.ai
