Turn the person's head to the side to prevent choking if he or she vomits.
With one hand, slightly pinch a fold of skin between your fingers.
Hold the syringe like a pencil close to the site, keeping your fingers off the plunger. Usually the syringe goes straight into the skin (90-degree angle). But for thin adults and small children with little fat, the needle may need to go in at a slant (45-degree angle) to keep the medicine from going into muscle.
Bend your wrist, and quickly push the needle all the way into the pinched-up area.
Push the plunger of the syringe all the way in so that the medicine goes into the tissue. Give the amount of glucagon that the person's doctor has recommended.
Remove the needle from the skin slowly and at the same angle that you inserted it.
Give some quick-sugar food when the person is alert.
