Label weight bands & CSACI guidance
The filter follows Canadian product labels: EpiPen Jr 0.15 mg at 15–30 kg, EpiPen 0.3 mg above 30 kg, and Neffy 2 mg at 30 kg or more. CSACI guidance supports a 0.3 mg autoinjector from 25 kg to reduce underdosing; that threshold differs from the EpiPen label. Below 15 kg, CSACI supports a 0.15 mg autoinjector when an appropriate lower-dose device is unavailable. These autoinjector recommendations do not change Neffy’s labelled weight threshold.
