Managing Insulin Mistakes: Wrong Insulin, Wrong Dose, and What To Do

Understanding Insulin Errors

• 💡 Mistakes with insulin are common and can happen to anyone managing type 1 diabetes, whether on MDI or a pump.
• ⚠️ It's crucial to know how to handle these situations before they occur to avoid panic and ensure safety.
• 🧠 Pumps often have safeguards against accidental large doses, but errors can still happen, especially with fast-acting vs. basal insulin mix-ups.

Dealing with Wrong Insulin Type

• 🎯 The most common error is injecting fast-acting (mealtime) insulin instead of basal (slow-acting) insulin.
• ⚖️ If this happens, the immediate thought should be to calculate the carbohydrate coverage needed for the injected fast-acting insulin based on your insulin-to-carb ratio.
• 📈 Use your Continuous Glucose Monitor (CGM) to track blood sugar trends and inform how much and when to consume carbohydrates to counteract the excess insulin.
• 💧 Consider consuming warm liquids with simple carbs to speed up absorption and stabilize blood sugar more quickly.

Managing Incorrect Insulin Doses

• 📉 If you accidentally take a double dose of basal insulin, the primary strategy is to eat an uncovered snack before bed (if taken at night) or be prepared for lower blood sugars and adjusted meal doses the next day (if taken in the morning).
• ⏳ Newer insulins like Tresiba have a flatter, longer action profile, meaning the effects of a double dose might last up to 24 hours, compared to older insulins like Lantus or Levemir which might last 18-20 hours.
• 🍕 Avoid complex foods like pizza immediately after an insulin error, as their slower digestion can lead to a dangerous situation where insulin is active but the food isn't providing enough counteraction.

Emergency Preparedness and Resources

• 🚨 In severe cases of hypoglycemia or extreme panic, glucagon is a vital tool, and it's essential to have it readily available.
• 📞 If you are severely affected, call 911 rather than attempting to drive yourself to the hospital.
• 📚 Having an emergency stash of simple sugars and knowing how to use them is critical for managing these unexpected events.

Real-Life Stories and Lessons Learned

• 👧 A harrowing story is shared about a 7-year-old girl who received 150 units of fast-acting insulin instead of 1.5 units due to a nurse's error, highlighting the critical need for vigilance and preparedness.
• 🩹 This incident underscores how distraction and lack of common sense can lead to severe mistakes, emphasizing the importance of double-checking and understanding insulin action.
• ✅ Ultimately, mistakes are human, but the goal is to prevent a mistake from becoming a disaster by having a plan and knowing how to react.
