The FDA posted the following at their website on November 5 about some U-40 syringes being packaged as U-100 syringes. Most folks in the US are using U-100 insulin, and U-100 syringes, and may be completely unaware that in other parts of the world, insulin is produced in U-40 strength, and corresponding U-40 insulin syringes are used. If someone uses U-100 insulin with syringes labeled for U-40 insulin, there's a mismatch, and a risk of getting 2.5 times as much insulin as expected.
