Insulin therapy

Administer insulin as prescribed, usually by subcutaneous injection with a standard insulin syringe. Subcutaneous insulin can also be given with a penlike insulin injector device that uses a disposable needle and replaceable insulin cartridges, eliminating the need to draw insulin into a syringe. Jet-injection devices are expensive and require special cleaning procedures, but they disperse insulin more rapidly and speed absorption.

These devices draw up insulin from standard containers (which allows the patient to mix insulins, if necessary, but requires a special procedure for drawing up) and deliver it into the subcutaneous tissue with a pressure jet.
