      Drug Name Foscarnet Balsalazide
      Mechanism Nephrotoxicity Nephrotoxicity
      Key Mechanism Factor 1
Factor Name Nephrotoxicity
Factor Description The combination of drugs that can induce nephrotoxicity may increase the risk of kidney injury. When kidney injury occurs, the inability to remove excess urine and waste from the body can lead to high levels of urea nitrogen, creatinine, and electrolytes (such as potassium and magnesium) in the blood.
      Mechanism Description
  • Increased risk of nephrotoxicity by the combination of Foscarnet and Balsalazide 

Recommended Action
      Management Caution is advised when 5-aminosalicylate preparations are prescribed to patients who have recently received or are receiving treatment with other potentially nephrotoxic agents (e.g., aminoglycosides polypeptide, glycopeptide, and polymyxin antibiotics amphotericin B adefovir cidofovir foscarnet cisplatin deferasirox gallium nitrate lithium certain immunosuppressants intravenous bisphosphonates intravenous pentamidine high intravenous dosages of methotrexate high dosages and/or chronic use of nonsteroidal anti-inflammatory agents). Renal function should be evaluated prior to and during 5-aminosalicylate therapy.
