The FDA has approved Merck Animal Health's VetPen, a refillable insulin injection pen for dogs and cats with diabetes. The device, used with Vetsulin insulin cartridges, allows for automatic measurement of the prescribed dose, making the system more accurate and easier to use, according to Merck. Vetsulin was pulled from the market in 2011 after testing flagged possible contamination with bacteria, but it was reintroduced in 2013. Read more from the FDA.
