Canine Addison's Zycortal Survey
This brief survey will be used as a tool to collect information about dogs who have made the transition from Florinef/Fludrocortisone/Astonin H to Zycortal.

We hope this will help show veterinarians the problems many dogs are experiencing when they are started on the standard dose of Zycortal and high doses of Prednisone/Prednisolone.

Many Canine Addison's groups, including CARE, AddisonDogs, Addisons Disease in Dogs, k9 Addison's, Morbus Addison beim Hund, & others, have joined together to publish this survey. Thanks to the members in all the Addison's groups who are providing feedback full of encouragement, input, and data. It has enabled Lori and Pam to put together this survey & will hopefully help vets make changes to help the dogs!

If you have more than one dog with Addison's, you can fill out more than one survey.

What was your dog's TOTAL daily dose of Florinef or Fludrocortisone in mg prior to Zycortal? For example, if you gave 0.4 mg twice per day, the total daily dose is 0.8 mg. (There has been some confusion: We are NOT asking for the total number of tablets given per day.)
Was your dog taking Prednisone or Prednisolone in addition to the Florinef/Fludrocortisone? If so, what was the dose in mg & how often was it given? (Not all dogs on Florinef/Fludrocortisone need Pred, so this might not apply to you - if so, answer, "No.")
What dose of Zycortal was your dog started on? Please give the dose in ml.
How many injections has your dog had so far?
If your dog has had more than one injection, how many days between doses?
How did you discontinue the Florinef?
Dogs on Zycortal need a small daily dose of Prednisone/Prednisolone. What dose of Pred was your dog started on? Please give the dose in mg & how often it is given.
Has the Prednisone dose been reduced? If so, to what amount? If not, are there plans to reduce it?
Please note any issues or side effects your dog has been experiencing since starting Zycortal and Prednisone.
