Instruct patients (if age appropriate) and caregivers:
• To watch for signs of allergic reactions such as urticaria, shortness of breath, wheezing and angioedema since hypersensitivity reactions may occur to any of the vitamins or excipients contained in multiple vitamins injection (adult).
• To watch for and immediately report nausea, vomiting, headache, dizziness, blurred vision, especially if patients have renal impairment, as these may be signs of hypervitaminosis A.
• To report other adverse reactions such as rash, erythema, pruritus, headache, dizziness, agitation, anxiety, and diplopia.
• That the patients on warfarin anticoagulant therapy will be monitored periodically with blood prothrombin/ INR levels to determine if their dose of warfarin needs to be adjusted.
• About the significance of periodic monitoring of blood vitamin concentrations to determine if vitamin deficiencies or excesses are developing and the need to monitor renal function, calcium, phosphorus, aluminum and vitamin A levels in patients with renal impairment.
• That multiple vitamins injection (adult) should be avoided in patients with suspected or diagnosed megaloblastic anemia prior to blood sampling for the detection of the folic acid and cyanocobalamin deficiencies.
• That vitamin C (ascorbic acid) contained in multiple vitamins injection (adult) may cause false negative urine glucose results.
