Adrenaline auto injectors, should I complain?

[MrsAvocet]

My DS has multiple allergies and has carried a Jext auto injector for years.
His current ones go out of date this month so I ordered a repeat as normal. I've just opened the bag and he's been dispensed EpiPens not Jexts. Obviously it's the same drug but the mechanism of action looks a bit different and neither he nor I have had any training. I guess we will figure it out - there'll be videos online I'm sure - but it seems dangerous to me to change an emergency drug without letting the patient know and checking they know how to use it?
I don't know if I'm being a bit precious as it's probably not that different, but as anyone who's ever had to use adrenaline in anger knows, it's a stressful experience and being faced with a different device would not help the situation. I remember the nurse who did our training years ago saying that it was important that we always got the same brand to avoid confusion in an emergency. Suppose I'd left it in the pharmacy bag and only opened it if it was needed? That's not the time to be reading the instructions!
Would you contact the surgery or just let it go?

I would mention it to the pharmacist. See if they can swap it, once you (calmly) explain about the training that you, your son and his carers have had with Jext.

Having said that, I got a practice Epi Pen from the pharmaceutical company when I registered my pens for expiry reminders. It's very simple, that's why it's the main pen issued in Australia.

This is interesting as we’ve always been prescribed one jext and epi pen (x2) and told to carry one of each brand in case there is a manufacturing fault with a particular batch.
Epi pen website has a video with the blue to the sky orange to the thigh slogan, which is worth a watch.

I would say given the chronic supply issues affecting adrenaline injectors over the last few years, especially junior ones, you were probably given what was available in the knowledge that the other one may not be available for a while.

I couldn't get different brand ones from my pharmacist when my prescribed ones weren't available. I had to get a new prescription. If it was a supply issue you're lucky they just gave it to you

It's not the pharmacy who have changed it - its the GP surgery. The repeat prescription form is in the bottom of the bag and it states EpiPen having been Jext for the last 12 years or so. I've had no difficulty getting Jexts for ages now and for the short period of time when there was a problem the pharmacy were very good at keeping me updated, so I don't think it's anything to do with supply. For some reason the GP has altered the prescription.

Epi-pen always seem like the better brand to me. Clearer instructions too. We've had a mix of epi-pen, jext and emerade over the years.

I would let it go tbh. They all work in pretty much the same way.
