Doses - DESOXYCORTICOSTERONE PIVALATE, (DOCP)
Dogs:Note: Dosage requirements are variable and should be individualized to the patient.
a) Initially, inject 2.2 mg/kg IM every 25 days. Monitor (serum potassium and sodium)and adjust as necessary. Most patients are well controlled at doses of 1.1 - 2.2 mg/kggiven every 21-30 days. (Proposed Package Insert for DOCP. Note: Not final and not
FDA-approved; refer to actual package insert for approved dose)
b) Initially, inject 2.2 mg/kg IM every 25 days. Because it has little or no glucocorticoidactivity, add prednisone or prednisolone at 0.2 mg/kg PO daily. Adjust dosages untildog is stable and otherwise healthy. Then slowly reduce glucocorticoid to a minimal orzero dosage. Perhaps one-half of all dogs will require no routine glucocorticoid, butshould have it available for emergencies. Monitor (serum potassium and sodium, BUN)and adjust as necessary. (Feldman, Nelson et al. 1992)
c) 1 - 2 mg/kg IM every 3-4 weeks (some dogs require up to 3 mg/kg) (Nichols, Petersonet al. 1994)
