Drug Interactions

Aldesleukin: Corticosteroids may diminish the antineoplastic effect of Aldesleukin. Avoid combination

Aluminum Hydroxide: Vitamin D Analogs may increase the serum concentration of Aluminum Hydroxide. Specifically, the absorption of aluminum may be increased, leading to increased serum aluminum concentrations. Avoid combination

Calcium Salts: May enhance the adverse/toxic effect of Vitamin D Analogs. Monitor therapy

Cardiac Glycosides: Vitamin D Analogs may enhance the arrhythmogenic effect of Cardiac Glycosides. Monitor therapy

Ceritinib: Corticosteroids may enhance the hyperglycemic effect of Ceritinib. Monitor therapy

Corticorelin: Corticosteroids may diminish the therapeutic effect of Corticorelin. Specifically, the plasma ACTH response to corticorelin may be blunted by recent or current corticosteroid therapy. Monitor therapy

Deferasirox: Corticosteroids may enhance the adverse/toxic effect of Deferasirox. Specifically, the risk for GI ulceration/irritation or GI bleeding may be increased. Monitor therapy

Hyaluronidase: Corticosteroids may diminish the therapeutic effect of Hyaluronidase. Management: Patients receiving corticosteroids (particularly at larger doses) may not experience the desired clinical response to standard doses of hyaluronidase. Larger doses of hyaluronidase may be required. Consider therapy modification

Multivitamins/Fluoride (with ADE): May enhance the adverse/toxic effect of Vitamin D Analogs. Avoid combination

Multivitamins/Minerals (with ADEK, Folate, Iron): May enhance the adverse/toxic effect of Vitamin D Analogs. Avoid combination

Sucralfate: Vitamin D Analogs may increase the serum concentration of Sucralfate. Specifically, the absorption of aluminum from sucralfate may be increased, leading to an increase in the serum aluminum concentration. Avoid combination

Thiazide and Thiazide-Like Diuretics: May enhance the hypercalcemic effect of Vitamin D Analogs. Monitor therapy

Vitamin D Analogs: May enhance the adverse/toxic effect of other Vitamin D Analogs. Avoid combination

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience itching, burning, or redness. Have patient report immediately to prescriber signs of high blood sugar (confusion, fatigue, increased thirst, increased hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), signs of high calcium (weakness, confusion, fatigue, headache, nausea and vomiting, constipation, or bone pain), signs of skin changes (acne, stretch marks, slow healing, or hair growth), severe skin irritation, skin discoloration, thinning of skin, weight gain, constipation, muscle weakness, or muscle pain (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
