allergic reactions
"My yellow Labrador was given an injection of triamcinolone.  She has been itching and scratching for 12 years.  We needed to get this stopped.  One injection and my pet has her life back and I have mine back as well.  This is truly a wonder drug.  We tried all the usual remedies with no improvement.  The Vet who was a substitute for our regular Vet was a chance encounter.  I praised him for improving my pet."
