Not suitable for use in small joints (eg, hand). Previously infected or unstable joints: not recommended. Increased risk of infections (viral, bacterial, fungal, protozoan, or helminthic). May mask signs of current infection. Avoid exposure to chickenpox or measles if unvaccinated. HPA axis suppression. Adrenal insufficiency. Supplement with additional corticosteroids in physiologic stress (eg, trauma, surgery, illness). Hypo- or hyperthyroidism. Patients with CHF, hypertension, renal insufficiency: monitor; dietary salt restriction and K+ supplementation may be necessary. Elevated intraocular pressure (monitor).

Potentiated by CYP3A4 inhibitors (eg, ketoconazole), cyclosporine, estrogens, macrolide antibiotics. Antagonized by CYP3A4 inducers (eg, barbiturates, phenytoin, carbamazepine, rifampin), cholestyramine. May potentiate cyclosporine (seizure risk). May antagonize oral anticoagulants (monitor), isoniazid. Aminoglutethimide may lead to loss of corticosteroid-induced adrenal suppression. Increased risk of arrhythmias with digitalis. May need to adjust dose of antidiabetic agents. Increased GI effects with aspirin or other NSAIDs. Caution with aspirin in hypoprothrombinemia. Monitor for hypokalemia with K+-depleting drugs (eg, amphotericin B, diuretics). Withdraw anticholinesterase agents at least 24hrs before initiating corticosteroid therapy. May suppress reactions to skin tests. Defer routine vaccine or toxoid administration until corticosteroid is discontinued.
