- Use a Turntable: If your microwave has a turntable, ensure the heat pack is placed on it to allow for even heating.
- Inspect Before Use: Always check the heat pack for any signs of damage, such as tears or leaks, before microwaving.
- Test Temperature: After heating, check the temperature of the heat pack on a less sensitive area of your skin before applying it to a sore spot.

Overheating a heat pack can cause it to become dangerously hot, leading to burns or even fire hazards. If the instructions suggest a specific time, it is best to start with that time and check the temperature before further heating.
