Dexamethasone
Also known as: Decadron, Dexasone, Azium, Maxidex
**Important Information for Pet Owners:** * **Increased Thirst and Urination:** Your pet will likely drink much more water and need to urinate more frequently. Ensure they always have access to fresh water and provide extra bathroom breaks to prevent accidents. * **Increased Appetite:** Your pet may seem unusually hungry. Avoid overfeeding to prevent unwanted weight gain. * **Panting:** Dogs may pant more than usual; this is a common and generally harmless side effect. * **Do Not Stop Abruptly:** If your pet has been on this medication for more than a few days, **do not stop giving it suddenly**. The dose must be gradually tapered under veterinary supervision to allow your pet's body to resume its own natural steroid production. > **Warning:** Contact your veterinarian immediately if you notice dark, tarry stools, vomiting (especially with blood), or extreme lethargy, as these can be signs of stomach ulcers.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.

Drug interactions
- NSAIDs (e.g., carprofen, meloxicam): Significantly increased risk of severe gastrointestinal ulceration and bleeding.
- Insulin: Dexamethasone induces insulin resistance, antagonizing the hypoglycemic effect of insulin and increasing requirements in diabetic patients.
- Phenobarbital: May induce hepatic enzymes, increasing the metabolism and clearance of dexamethasone.
- Diuretics (potassium-depleting): Increased risk of hypokalemia.
