Psychosis, diabetes mellitus, glaucoma, osteoporosis, seizure disorders, ulcerative colitis (intestinal perforation), CHF, hypertension, myesthenia gravis (if .used with anticholinesterase agents), renal disease, esophagitis, peptic ulcer, latent tuberculosis or amebiasis (reactivation of disease).


Topical: use on face, groin, or axilla, ocular herpes simplex.


Old age: Use with caution

Interaction:

Drugs


Aminoglutethamide: Increased clearance of steroid; doubling of dose may be necessary


Antidiabetics: Increased blood glucose


Barbiturates, carbamazipine: Reduced serum concentrations of corticosteroids


Cholestyramine, colestipol: Possible reduced absorption of corticosteroids


Cyclosporine: Possible increased concentration of both drugs, seizures


Erythromycin, troleandomycin, clarithromycin, ketoconazole: Possible enhanced steroid effect


Estrogens, oral contraceptives: Enhanced effects of corticosteroids


lsoniazid: Reduced plasma concentrations of isoniazid


IUDs: Inhibition of inflammation may decrease contraceptive effect


NSAIDs: Increased risk of GI ulceration


Rifampin: Reduced therapeutic effect of corticosteroids
