Dexamethasone
別名: 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.
劑量必須由獸醫按你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。

藥物相互作用
- 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.
