Low Blood Sugar Away From Home: Why Glucose Belongs in a Medical Kit

When people think about a first aid kit, they usually picture bleeding, burns, and bandages. Those supplies matter, but medical problems do not always come with a visible injury. For someone at risk of low blood sugar, having fast-acting glucose nearby can be just as important as having something to stop the bleeding.

Low blood sugar, or hypoglycemia, is a particular concern for people taking insulin or certain other diabetes medications. A delayed meal, more activity than usual, or alcohol without enough food can contribute to a low. A road trip, hunting trip, or busy workday can change someone’s routine without changing their need to monitor and manage their blood sugar. ^[1]

Shaking, sweating, hunger, dizziness, and a racing heartbeat can be early warning signs. Irritability or confusion may also occur, and some people have little warning at all. For most people with diabetes, a reading below 70 mg/dL requires action. Check with a glucose meter or continuous glucose monitor when available rather than assuming someone is simply tired or hungry. ^[2]

When oral glucose can help

For an adult with low blood sugar who is awake, alert, and able to swallow safely, CDC recommends the 15-15 rule: take 15 grams of fast-acting carbohydrate, wait 15 minutes, and check again. If the reading remains below 70 mg/dL, repeat. Follow the person’s diabetes care plan; young children may need a smaller amount determined by their care team. ^[3]

Glucose tablets make the amount easier to measure, but always read the package. Four ounces of juice or regular, non-diet soda is another option. Chocolate and peanut butter are slower choices because fat can delay sugar absorption. Once blood sugar has recovered, a snack containing carbohydrate and protein can help if the next meal is not soon. ^[2]

Know when to call for help

Someone who is severely confused, having a seizure, unconscious, or unable to swallow safely needs emergency help. Call 911 and do not put food, drinks, glucose tablets, or gel into their mouth. If prescribed glucagon is available, someone who knows how to administer it should follow the device instructions and the person’s emergency plan. Oral glucose cannot replace glucagon or emergency care in this situation. ^[4]

This is why Module 4: Medication & Hydration includes sunmark® TRUEplus™ orange-flavored glucose tablets in a compact, 10-tablet tube. Each tablet provides 4 grams of glucose, so four tablets provide 16 grams, approximately the amount used in the 15-15 rule. Follow the package instructions and the person’s diabetes care plan. ^{[3], [5]}

For someone with diabetes, a medical kit should supplement their personal supplies, monitoring equipment, and prescribed emergency medications. Keep those essentials accessible, and make sure a traveling companion knows where they are. Being prepared includes having the right supplies and knowing when they are appropriate to use. ^[6]

Key Takeaway

• Recognize the warning signs and check blood sugar promptly.
• Use oral glucose only when the person is alert and can swallow safely.
• Call 911 for severe symptoms and follow the person’s prescribed emergency plan.
