But there have been reports of unusual fluctuations in glucose readings, especially during the last day of the sensor’s life.

Overall, users appreciate the functionality and ease of use of the FreeStyle Libre. Such information is crucial to share with your doctor to help determine your diabetes treatment plan. For example, you may notice they’re stabilizing or trending upward or downward. When used over time, the monitor can also help you see patterns in your blood sugar levels. It can indicate either hyperglycemia, where your glucose levels are too high, or hypoglycemia, where your levels are too low. Like traditional blood glucose monitors, the FreeStyle Libre gives you information about your sugar levels. Now, you can wear it for up to 14 days at a time. The original FreeStyle Libre allowed users to wear the sensor wire for up to 10 days before switching it out. You should check your levels at least every 8 hours. Since the FreeStyle Libre doesn’t have automatic alerts when your blood glucose is at dangerous levels, it’s important to set reminders to regularly check your monitor. Instead of checking your glucose several times a day with a finger stick, you wave the monitor above the sensor in your skin to check your levels anytime you wish. This process is said to be painless, but some users experience mild skin irritation. The sensor itself is about the size of a coin and is applied just underneath the top layer of your skin. To set up the FreeStyle Libre, you must first insert the sensor into your upper arm with an applicator that’s included with the set. Here’s a breakdown of how to use the monitor.
