For administration, you need to hold a Jext pen against your thigh while in the case of an EpiPen, you need to hold it 10 cm away from your thigh.

For the Jext pen, you have to hold it firmly for 10 seconds while in the case of an EpiPen, you need to hold it for 3 seconds.

After administering Jext, you need to massage the injection site for 10 seconds. For EpiPen, you do not need to massage the injection site.
