What is Dexamethasone?

Dexamethasone is a synthetic analogue prednisolone, having similar but more potent anti-inflammatory therapeutic action and diversified hormonal and metabolic effects.

How is this medication given?

This medication is given by injection. Dexamethasone may be given with food (preferred way) or without food. If your animal vomits or acts sick after getting it on an empty stomach, give with food or small treat to see if this helps. If vomiting continues, contact your veterinarian.

How long should I give my pet Dexamethasone?

The goal with dexamethasone is to find the lowest dose possible and use for the shortest period of time. Do not discontinue the drug on your own without first talking with your veterinarian.

    Injectable steroid

    By Dexamethasone on Jul 8, 2021

    Prescription arrived very quickly, needed this to help treat a dog with Addison’s disease, as he is prone to an Addisonian crisis due to fear of fireworks. This saved me a trip to ER vet.

    Always wonderful

    By Jami on Nov 4, 2020

    Chewy has always come through for me! The prescriptions have been hard to get due to covid and Chewy has remained a trusted and reliable source for me. Without these meds, my horse would not be here with me. Thank you!
