Method of Injection
As stated previously, insulin cannot be delivered orally because stomach acids render it useless before any action can take place.
Worn outside the body, an insulin pump delivers a continuous supply of insulin through a tube that connects to a needle placed under the skin. This amount may be supplemented before meals depending on blood glucose levels.
An insulin pen is a device that stores replaceable insulin cartridges with a sterile, disposable needle. These devices eliminate the need to carry extra bottles and needles.
Using high pressure to expel the insulin through the skin, jet injectors do not require a needle. This is an expensive option for insulin delivery.
Jet Nebulizers are currently being researched as a method for delivering insulin. This method is best described as "inhaled" insulin. Thus far no significant adverse reactions have been noted but efficacy is questionable.
When injecting insulin it is important to choose the correct location. It is critical to rotate sites following a regular pattern. Uptake of insulin is fastest in the abdomen and slowest from the buttocks. Repeated injections in the same area may cause delayed absorption. Quicker absorption of insulin can result from exercising (arms and legs) the area of injection.
