When used properly, insulin can be an essential tool for managing type 2 diabetes. Here’s what to do and what not to do when it comes to injecting insulin.
When diet, exercise, and oral medications aren’t enough to manage type 2 diabetes, it may be time for insulin. The most important aspect of insulin therapy is using it exactly as prescribed.
Still, remembering all the little details can be tricky, and certain mistakes are common. By following these dos and don’ts, you can avoid medication mishaps and keep insulin working as it should.
DO: Rotate the insertion site (while keeping the body part consistent). “Insulin is absorbed at different speeds depending on where you inject it, so it’s best to consistently use the same part of the body for each of your daily injections,” says Doreen Riccelli, BSN, director of education at Lake Pointe Medical Center in Rowlett, Texas. “For example, don’t inject yourself in the abdomen on Saturday and in the thigh on Sunday,” she says. “If you choose the thigh for your evening injection, then use the thigh for all of your evening injections.”
That said, within the specific body area, it’s important to move each injection site at least one finger’s width from the previous injection site to avoid the creation of hard lumps or extra fat deposits, which could change the way insulin is absorbed.
DON’T: Store insulin incorrectly. Insulin can generally be stored at room temperature (59 to 86° F), either opened or unopened, for one month. When kept in the refrigerator, unopened bottles last until the expiration date printed on the bottle. Opened bottles stored in the refrigerator should be used or discarded after a month.
Never store insulin in direct sunlight, in the freezer, or near heating or air conditioning vents, ovens, or radiators. It should also not be left in a very warm or cold car. Store it in an insulated case if needed.
