MONITOR CLOSELY: Coadministration of intravenous immune globulin preparations with nephrotoxic agents may potentiate the risk of renal impairment. Many commercially available intravenous formulations of immune globulin contain sucrose as a stabilizer. Immune globulin products, particularly those that contain sucrose as a stabilizer and administered at daily doses of 350 to 400 mg/kg or greater, have been associated with renal dysfunction, acute renal failure, osmotic nephrosis, and death. Factors predisposing to acute renal failure include any degree of preexisting renal insufficiency, age greater than 65 years, diabetes mellitus, volume depletion, sepsis, paraproteinemia, and concomitant use of known nephrotoxic drugs.

MANAGEMENT: Intravenous immune globulin preparations should be administered cautiously in patients treated with other potentially nephrotoxic agents (e.g., e.g., aminoglycosides; polypeptide, glycopeptide, and polymyxin antibiotics; amphotericin B; adefovir; cidofovir; tenofovir; foscarnet; cisplatin; deferasirox; gallium nitrate; lithium; mesalamine; certain immunosuppressants; intravenous bisphosphonates; intravenous pentamidine; high intravenous dosages of methotrexate; high dosages and/or chronic use of nonsteroidal anti-inflammatory agents). The manufacturers recommend administering immune globulin infusions at the minimum concentration available and at the minimum rate of infusion feasible in such patients. Clinicians should ensure that patients are not volume depleted prior to the initiation of immune globulin therapy. Monitoring of urine output and renal function tests, including the measurement of blood urea nitrogen (BUN) and serum creatinine, is recommended prior to the initial infusion and at appropriate intervals thereafter. If renal function deteriorates, discontinuation of the product should be considered. Patients should be advised to seek medical attention if they experience symptoms that may indicate nephrotoxicity such as decreased urine output, sudden weight gain, fluid retention, edema, or shortness of breath.

Food, especially calcium-containing food such as dairy products, significantly decreases the absorption of etidronate. For at least the first 2 hours after taking etidronate, do not eat or drink anything other than plain water, and do not take any other medicines including vitamins or mineral supplements which are high in metals such as calcium, iron, magnesium, or aluminum. Use only plain water (not mineral water) when taking etidronate tablets.

Etidronate and multivitamin with minerals should not be taken orally at the same time. Products that contain magnesium, aluminum, calcium, iron, and/or other minerals may interfere with the absorption of etidronate into the bloodstream and reduce its effectiveness. You should take multivitamin with minerals at least 2 hours before or 2 hours after the etidronate dose. Talk to a healthcare professional if you are not sure whether a product contains something that could potentially interact with your medication or if you have questions on how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
