Juice boxes, glucose drinks, and glucose gels work well to treat lows most times of the year, but if you take these on an outdoor excursion or leave them in a parked car in the winter, they could freeze. That can leave you without fast-acting glucose should you develop hypoglycemia (low blood glucose).
The Fix: Glucose tablets or powders are a safer bet because they don’t freeze. Pay attention to your glucagon injection kit, too. It should be stored at 68 to 77 degrees. Liquid in a glucagon injection can freeze if you store your kit in your car or take it outside in cold temps. Keep it close to your body, or opt for Eli Lilly’s recently approved nasal glucagon powder, Baqsimi.
