Types of Pens
A number of companies make insulin pens including Novo Nordisk, Aventis and Eli Lilly. These companies produce pens for most of their insulins, including NovoLog/NovoRapid, Humalog, Levemir and Lantus.
There are two pen systems: durable and prefilled:
- A durable pen uses a replaceable insulin cartridge. When the insulin cartridge is empty, the empty cartridge is disposed of and a new one is inserted in the pen.
- A prefilled pen is entirely disposable. The pen comes pre-filled with insulin, and when the insulin cartridge or reservoir is empty, the entire unit is discarded.
Most brands of insulin are now available for use in pens, these include:
- NovoLog, NovoRapid and Levemir by Novo Nordisk
- Lantus and Apidra by Sanofi-Aventis
- Humulin and Humalog by Eli Lilly and Company

Famous quotes containing the words types of, types and/or pens:
“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)
“There is no one kind of thing that we ‘perceive’ but many different kinds, the number being reducible if at all by scientific investigation and not by philosophy: pens are in many ways though not in all ways unlike rainbows, which are in many ways though not in all ways unlike after-images, which in turn are in many ways but not in all ways unlike pictures on the cinema-screen—and so on.”
—J.L. (John Langshaw)
