Freestyle Libre 2 Sensor

Freestyle Libre 2 Sensor for Continuous Glucose Monitoring

The FreeStyle Libre 2 sensor is a continuous glucose monitoring (CGM) sensor designed to track glucose levels day and night without routine finger-prick blood sampling. Worn on the skin for up to 14 days, the sensor measures interstitial glucose and delivers readings with a quick scan using a compatible reader or smartphone app. It is widely used in veterinary practice to support the monitoring of diabetic dogs and cats.

Main Uses

• Provides continuous glucose readings to support the management of diabetes mellitus in dogs and cats.
• Helps identify glucose trends, including overnight patterns and post-meal excursions, that spot blood checks may miss.
• May reduce the need for repeated ear-prick or venous blood sampling during glucose curve assessments.
• Supports veterinary decision-making when adjusting insulin therapy, alongside clinical signs and laboratory testing.

The FreeStyle Libre 2 sensor is a monitoring aid. It does not replace veterinary assessment, and insulin doses should only be adjusted under veterinary direction.

Key Features

• Up to 14 days of continuous wear per sensor.
• Scan-based readings: glucose values, trend arrows and an 8-hour history retrieved with a painless 1-second scan.
• Small, discreet sensor worn on the skin; applied with a single-use applicator.
• Optional real-time glucose alarms (high/low) when used with a compatible smartphone app.
• Water-resistant design for normal daily activity.

Directions for Use

• The sensor should be applied and positioned by, or under the guidance of, a veterinarian.
• Scan the sensor with a FreeStyle Libre 2 reader or a compatible smartphone app (reader/app sold separately).
• Check that readings correlate with clinical signs; confirm unexpected results with a blood glucose meter if advised by your veterinarian.
• Replace the sensor after 14 days or as directed by your veterinarian.

Safety and Precautions

• For veterinary monitoring use under the direction of a veterinarian.
• Do not rely solely on sensor readings to make insulin dosing decisions; consult your veterinarian.
• Discontinue use and consult your veterinarian if skin irritation occurs at the application site.
• Keep out of reach of children and animals. Single-use only; do not reuse a sensor.

Storage

Store at room temperature in a dry place. Do not freeze. Keep the sensor in its sealed applicator pack until use.
