• Monitor weight, blood pressure, and electrolyte levels.
• Watch for cushingoid effects (moon face, central obesity, buffalo hump, hair thinning, high blood pressure, frequent infections).
☞ Assess patient for depression and psychosis.
• Monitor blood glucose level carefully in diabetic patient.
• Evaluate for signs and symptoms of infection, which drug may mask or exacerbate.
☞ Monitor for signs and symptoms of early adrenal insufficiency (fatigue, weakness, joint pain, fever, anorexia, shortness of breath, dizziness, syncope).
• Assess musculoskeletal status for joint, tendon, and muscle pain.
• Tell patient to take oral dose with food or milk to reduce GI upset.
• Instruct patient to remove ODT tablet from blister just before taking.
• Instruct patient to place ODT tablet on tongue and either swallow tablet whole or allow it to dissolve in mouth with or without water. Caution patient not to cut, split, or break tablet.
☞ Teach patient to recognize and immediately report cushingoid effects and signs and symptoms of early adrenal insufficiency.
☞ Advise patient and significant other to immediately report depression or psychosis.
• Explain that drug increases risk of infection. Instruct patient to contact prescriber at first sign of infection.
☞ Caution patient not to suddenly stop drug (including ophthalmic forms). Instruct him to discuss any changes in therapy with prescriber.
☞ Tell patient to immediately report bleeding or joint, muscle, tendon, or abdominal pain.
• Inform patient that he may need higher dosage during periods of stress. Encourage him to wear or carry medical identification stating this.
• Tell patient to avoid vaccinations during therapy. Mention that others in household shouldn't receive oral polio vaccine because they could pass poliovirus to him.
• Caution patient not to take over-the-counter drugs or herbs during therapy.
• Teach patient how to use eye drops. Caution him not to touch dropper tip to eye or any other surface.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, herbs, and behaviors mentioned above.
