Priming your HUMALOG Mix50/50 KwikPen:

Step 8: Hold your Pen with Needle pointing up. Push the Dose Knob in until it stops, and “0” is seen in the Dose Window. Hold the Dose Knob in and count to 5 slowly.
- A stream of insulin should be
seen from the needle.
- If you do not see a stream of insulin, repeat steps 6 to 8, no more than 4 times.
- If you still do not see a stream of insulin, change the needle and repeat steps 6 to 8.
Selecting your dose:
Turn the Dose Knob to select the number of units you need to inject. The Dose Indicator should line up with your dose.

- The HUMALOG Mix50/50 KwikPen will not let you dial more than the number of units left in the Pen.
- If your dose is more than the number of units left in the
Pen, you may either:
- inject the amount left in your Pen and then use a new Pen to give the rest of your dose, or
- get a new Pen and inject the full dose.
