Dexasone functions similarly to prednisolone, having anti-inflammatory therapeutic action and hormonal and metabolic effects. Dexasone may be used as a supportive therapy in inflammatory conditions such as arthritic conditions, snake bites, acute mastitis, shipping fever, pneumonia, laminitis and retained placenta.The dosage of Dexasone required can be lower than that of prednisone and prednisolone.


As supportive therapy, Dexasone may be used in the management of various rheumatic, allergic,dermatologic, and other diseases known to be responsive to anti-inflammatory corticosteroids.Dexasone may be used intravenously as supportive therapy when an immediate hormonal response is required.

Possible Side Effects

Side effects, such as SAP and SGPT enzyme elevations, weight loss, anorexia, polydipsia, and polyuriahave occurred following the use of synthetic corticosteroids in dogs. Vomiting and diarrhea (occasionally bloody) have been observed in dogs and cats. Cushing's syndrome in dogs has been reported in association with prolonged or repeated steroid therapy. Corticosteroids reportedly cause laminitis in horses.

Drug & Food Interactions

Before giving Dexamethasone, talk to your veterinarian if the pet is being given any other oral steroid medications, such as prednisone, prednisolone, methylprednisolone or others. Tell your vet if the pet is being given furosemide, non-steroidal anti-inflammatory drugs, such as carprofen, deracoxib or etodolac. Drugs other than those listed may also interact with dexamethasone. Talk to your vet before giving any prescription or over the counter medicines.


Animals receiving Dexasone should be under close observation. Because of the anti-inflammatory action of corticosteroids, signs of infection may be masked and it may be necessary to stop treatment until a further diagnosis is made. Overdosage of some glucocorticoids may result in sodium retention, fluid retention, potassium loss, and weight gain.
