Having been a mom to a beauty with Addison's I agree with JeepinDog on a bunch of issues. (It's obvious you've been on the roller coaster too but you've got all the info for sure!)
The one thing I can't stress to you Addisonian noobs enough is to be prepared!
Things we learned about needles:
*Needles 'bodies' come in various sizes. Make sure the size you get accommodates the injection size you are giving. In a rush the vet/vet tech may accidentaly hand you a small one
*On most of the bigger body needles the injector is a bigger needle, but the smaller needles often are more comfortable for your pet.
*consider buying the smaller needles only and the bigger body (you can also switch out the needles)
*Dispose of the needles properly, you can use a plastic jug or coffee can, jut label properly
ALWAYS, have a back up plan.
You never realize how important it is to at least acknowledge what a plan would be, because it's not fun running into the first establishment that's open for miles and flip through the yellow pages to find the local vets.
Have paper work with his diagnosis from your vet to make an emergency QUICK.
Vacation
If you are leaving your dog at home during vacation MAKE SURE the person caring for them understands the situation and how grave it can be. Think about calling your vet ahead of time, faxing a letter etc. and let them know who will be taking care of your pet and maybe bringing them in if necessary. This way your account can be 'credited' and you can pay when you get back.
Bring your own PercortenV and syringe with you, when traveling etc. if possible.
It's not something that all vets stock.
If they do, it might only be one vial AND it could be half full.
The nice part is Addison's is a disease that does not typically involve drugs that people want (like ketamine etc.) So if you need the drugs and do not have paper work with you (like on vacation), they are likely to believe you. Especially if you remember the exact injectable amount. Plus, with the cost, who would fake that need!
(Yes, this happened to us *stupid, stupid

)
We went on vacation to a semi-rural area, luckily the 1 vet in town that was on call trusted us and our needs without contacting our vet to confirm the diagnosis. He watched us inject him and done.
