Heparin FDA Alert

In case you had not heard, there was a major recall of Baxter's Heparin. It was responsible for dozens of deaths in the USA and an investigation was launched. It has been found that the contaminant comes from manufacturing plants in China. The most concerning part is that it looks like it was chemically synthesized sulfated chondroitin. This brings the suspicion of intentional adulteration. First lead in toys now cartilage in our heparin - what's next?

Some fascinomas of Heparin:

  • Overdose of heparin is treated with either time or protamine
  • Protamine can actually worsen anticoagulation if you give too much
  • Dose of Protamine: 1 mg of Protamine neutralizes 90 USP Units of Heparin but you must cut dose in half if 30 minutes have passed from heparin dose
