Insulin Delivery

Insulin is received by patients using a variety of devices. The most common include a syringe, pen and pump. Insulin can be drawn from a vial into a calibrated syringe and injected subcutaneously (under the skin). A great number of insulins are prepared in pens. These pens are calibrated in doses, making it convenient for patient use. Pens are easier for patients to carry and doses are more accurate.

Insulin is also available in an inhaled powder, technosphere (Afrezza). It is a short-acting regular prandial insulin. This product carries a warning for risk of acute bronchospasm in patients with chronic lung disease. It is contraindicated in patients with COPD and asthma.

Insulin is also delivered in a continuous subcutaneous infusion by pump of a rapid or short-acting class on a continual basis. The pump is calibrated to deliver patient controlled doses when meals are eaten.
