Azium is a steroid and it will help take away inflammation from the back problem. There can be some side effects if this drug is used at high doses for a long time. Some dogs on Azium will eat like they cannot get full, their belly may get larger from enlarged liver, and they may pant more than usual.esolved Question: My toy poodle has been prescribed Azium 2.5mg tablets; twice daily for 3 days then once daily for 3 days, then 1 every 48 hours for an apparent hip/back problem (symptoms: stiffness, non-activity, tremors). The med seems to be improving the problem.
