What is a subcutaneous injection?

A subcutaneous injection is when medicine is given into the tissue just below the skin. It is given with a special syringe and a very small needle. The injection (shot) can be in the legs, arms or belly.

Sometimes the medicine is in a prefilled syringe. This is a syringe with the medicine already in it and ready to go. Sometimes you have to draw the medicine up into a syringe from a vial. A vial is a small glass container that has a rubber stopper on the top. By piercing the rubber stopper with a needle, you can draw out the right amount of medicine.
