Yep - we've just been moved off EpiPen to one of the others (I forget which). Interesting is the network effect of EpiPen - many people have been trained to use them and are aware of there exact look and feel. For the new pens they are used in a similar but different way (I think the new ones are actually better/easier) but that might put some people off moving, where they do have a choice (not all doctors are being as strict with moving to the new version).
