Hi Courtney

When you have a severe hypo, there are two ways of treating it. The first is a glucagon injection into the muscle in the top of your leg (your parents should have glucagon at home). Glucagon works by helping the stored glucose to be released from your liver and raise your blood glucose level. Sometimes if an ambulance is called to treat you for a severe hypo, they will use glucagon.

The second way of treating a severe hypo that may be used when an ambulance is called, is for them to give you glucose into a vein, usually in your wrist.  This raises blood glucose levels and can only be done by ambulance staff or in hospital.

We think the needle you’ve had at school would have been an immunisation.  Sometimes when you have this type of needle, you can get a skin reaction where the needle went in.  This reaction is not likely to be related to the glucose you were given into your vein.
