Warning: Don’t Share Insulin Pens
If you use insulin pens or take other injected diabetes medications (such as Symlin, Victoza, or Byetta), don’t share your medication pen with anyone else—even if you’ve attached a new needle. Blood can get stuck inside the pen from previous use and could potentially infect another user. After receiving reports of thousands of situations where patients shared insulin pens, the Food and Drug Administration (FDA) now requires pen manufacturers to include a “for single patient use only” warning label on pens and pen cartons. So far, there have been no reports of actual infections in patients from pen sharing, and the FDA hopes to keep it that way.
