How to prevent the dose knob from being difficult to push
Injection Technique:
- Prime the KwikPen before each injection to remove air from the cartridge and to ensure the pen is working correctly.
- If the dose knob is hard to press, push the dose knob down more slowly as this will make it easier to inject. 2
Proper Pen Needle Use:
- Do not apply pressure to the dose knob when the pen needle is not attached because there is no path for medicine to flow, which will increase the pressure in the cartridge and cause the septum to bulge and may result in medicine wastage when a needle is attached.
- Always attach a new compatible needle to the KwikPen before each dose.
- Ensure the needle is not damaged, bent or broken.
- Confirm the pen needle is securely attached. This is essential in order for the medication to flow properly.
- The dose knob may be difficult to push if anything blocks or interrupts the flow of medicine into the pen needle.1
- Store the KwikPen in a clean and dry place. The KwikPen
- must NOT be stored with the needle attached, to prevent leaking, blockage of the needle and air entering the pen.
- must be stored with the pen cap attached.
- The dose knob may become hard to push if the pen is exposed to lint, dust, food or liquid.
- If this occurs dispose of the pen.
