Disposable pen needles are sold separately from the insulin pens and usually need a prescription. You attach them by screwing or snapping the needle onto the pen pointer. Taking the needle from its product packaging, connecting it, eliminating the safety cap, and discarding the needle when ended up can need nimble fingers and a common sense of touch to avoid accidental finger sticks. If this is a problem for you, ask your health care supplier which needle may be simplest to use. Owen Mumford Unifine Pentips Plus have a built-in eliminator, for example. The NovoFine Autocover has a needle shield that instantly secures location after injection. The BD AutoShield Duo hides the front of the sharp prior to and after injection and covers the back of the sharp on removal from the pen.
It’s excellent practice to alter your needle after each injection. Fresh, sharp needles might help in reducing painful sensations.
Pen needles been available in different lengths — including 4, 5, 6, 8, and 12.7 millimeters, shown listed below. Studies have revealed that a shorter needle works for all physique.
The density of a pen needle, not its length, is what affects any feeling of pain. The thickness of a needle is determined by its gauge — the higher the gauge, the thinner the needle. Gauges range from 29 (thickest) to 32 (thinnest). If you inject a big dose of insulin, a lower-gauge (thicker) needle might produce quicker medication delivery and ensure none leakages from your skin.
The shortest, thinnest pen needles offered are 4-millimeter, 32-gauge products. Becton, Dickinson and Co. (BD Nano), Novo Nordisk (NovoFine Plus), and Owen Mumford (Unifine Pentips) make this size.
