On March 27, 2024, the U.S. Food and Drug Administration (FDA) announced that Amneal Pharmaceuticals, LLC, is voluntarily recalling four lots of vancomycin hydrochloride for oral solution USP, 250 mg/5 ml, packaged in 80 ml, 150 ml, or 300 ml pack sizes, to the consumer level.

Amneal said that during the manual bottle-filling stage of manufacturing, some bottles may have been overfilled, which can result in overdosing. The recommended maximum daily dose allowance for the product is up to 2 gm per day, but if the affected product is used in patients who are prescribed that dose, they could receive up to 4 gm per day.

The excess dose may be harmful for patients with renal insufficiency. Worsening renal function could be associated with electrolyte abnormalities such as high potassium leading to cardiac arrest. Some patients with inflammatory disorders of the intestinal mucosa may already have significant systemic absorption of vancomycin and may be at risk for adverse reactions associated with higher doses. To date, Amneal said that it has not received any confirmed reports of adverse events directly related to the recall.

Vancomycin hydrochloride for oral solution USP, 250 mg/5 ml, is administered orally for treatment of enterocolitis caused by Staphylococcus aureus (including methicillin-resistant strains) and antibiotic-associated pseudomembranous colitis caused by C. difficile.

The following lots, which were distributed in the United States to wholesalers and distributors from November 9, 2023–February 20, 2024, are affected:
